CHEAP WI-FI MESH ALTERNATIVE with fast roaming OpenWrt Wi-Fi Access points

[@OneMarcFifty]

*IMPORTANT UPDATE* : If you don't see the 802.11r options in the luci Web interface then please go to system-software and *_install the package wpad-basic_* . Then you might need to reboot the device. By default OpenWrt has a light or mini version of wpad installed that doesn't have that option. Sorry I forgot to mention that step in the video.

[@hir3npatel]

I guess both APs must be openwrt ideally then, since most other firmware don't let you set 802.11r or such roaming settings?

[@OneMarcFifty]

Honestly- I don‘t know. It may be that modern APs have it on by default or maybe they call it differently...

[@keylock32]

Hi, I don't see wpad/or wpad-basic in software menu only wpad-mini, my old router is using 18.0.6.9 build and this is the latest and last update for it since it only have 4MB rom, how to install it?

[@OneMarcFifty]

@@keylock32 You will need wpad-basic or full wpad. Please check this article: forum.openwrt.org/t/cannot-install-package-wpad/49417/3 In 18.06 the option should then be visible in Luci. If it is not then you may add the directive in your /etc/config/wifi manually : option mobility_domain 'e612' #same for all APs option ieee80211r '1' option ft_psk_generate_local '1' see here: www.reddit.com/r/openwrt/comments/515oea/finally_got_80211r_roaming_working/

[@keylock32]

@@OneMarcFifty Unfortunately there's no free space left in software packages for wpad to be installed, even after removing lot's of opkg, it still doesn't do much, the left over space by default is only 64kB, Imanage to uninstall lot's of thing and get 250kB, and wpad requires 455kB, I gather the information the fast roaming mainly only for router which had 8MB Rom or bigger. I guess that's the main reason why they no longer supports 4/32 routers anymore. My old router is WR740N and I also had unused WA701ND I want to try this method unfortunately this is just hardware limitation, the option is showing up just fine for my main router Gl.Inet MT300Nv2

[@kerembildik9997]

4 years ago, I moved from a small house, WiFi worked well. Then I moved to another house with 2 floors and that house had adsl. I only had 1 modem which our ISP provided. Then I changed our ISP and this ISP didn't provide a modem. I bought a modem, that didn't give much performance, then a repeater, another repeater, Powerline adapters, swithces etc. I recently bought Zyxel multy U 3 pack (because it was the cheapest mesh wifi) . I sold it today because the only way to change settings was a phone app. Which doesn't work without internet. It's a garbage. Tomorrow I'm going to buy a Xiaomi 4a giga version. I'll build a mesh network with 3 of them in the future. By the way, I appreciate so much for this tutorial. It'll help me a lot. Like your other videos did. Thank you.

[@OneMarcFifty]

Many thanks for your feedback! I am sure glad this could help you simplify things ;-) 6 SSIDs sounds difficult to manage;-)

[@WoMaNA4]

Hi Marc, well illustrated and explained! I want to clarifiy that using different ESSIDs for APs on each floor, e. g. WLAN-0, WLAN-1, WLAN-2 (which was my original intention) disables the roaming or FT feature. So all APs for roaming must have equal ESSID, pre-shared key and mobility domain. WLAN-EG (EG in Germany means "street level" floor ) made me think that your APs would use different ESSIDs for the floors they are located at. At 05:09 when you show the WIFI analyzer we can see that it is not the case. So friends from Germany do not think too much about what "EG" could mean ... just give all APs the same ESSID :-)

[@OneMarcFifty]

Awesome comment, many thanks - and... actually very well observed ;-) you are right that "EG" was intended to be the abbreviation for ground or street level. When I initially set up my Wi-Fi I had 3 of them: UG (basement), EG and OG (upstairs). But once I figured out that life is so much easier with just one of them I just arbitrarily kept EG. I was just too lazy to rename it because I would need to go to every single Wi-fi device in my home and change it....

Open-WRT looks very powerful but also much harder to configure than Unifi but that may just be because I'm used to it.

I am building a large wireless network for a large agricultural application. I'm using ubiquiti airmax gear, which works well but it is a terribly walled in ecosystem. I am toying with the idea to install OpenWRT on all the hardware to enable better integration with end devices and get rid of Airmax. You asked the question, so I thought I would give you an answer. Currently the longest distance to an end point I am sending data wirelessly is 68km!

[@OneMarcFifty]

Wow - 68 Km ? Is that without any relays in between ? What's the data rate over that distance ? Which frequency band ?

[@rediculousman]

@@OneMarcFifty I have one 35km P2P link that operates at approx 90Mb/s and then the final distance is from the access point to the station. That link is about 15Mb/s as I don't need that particular one to be very fast, I only used a mid range radio. It's in a remote area, so interference isn't an issue, but line of sight is. I am operating in the 5GHz band.

Great video! Used this to setup my 3 GL Inet B1300s which were previously setup with mesh using the original firmware (which is based on openwrt 15). They each have a hardwired ethernet cable so I figured that I actually didn't need the mesh and it bothered me that they were using such and old version of openwrt. They're working great so far. I still may tweak the signal strengths but I'm happy with how it's working. Also, I will add that originally I wasn't able to put my 5GHz wifi channels side by side... after trying to use channel 52 I found it just wouldn't work. After setting my country (Canada) I was able to use channel 52 and set them all up side by side.

Hi John, you're pointing out one of the crucial settings here - the country code. This always needs to be set to the same value on all Wi-fi interfaces in order to have things like DFS work correctly.

[@aakashmaroti1891]

Correct me here if my understanding is wrong, 802.11r alone will only help me reconnect to an access point faster AFTER my signal has deteriorated significantly. Probably something like 802.11k or 802.11v or a controller or something else altogether is required for a seamless and timely handover.

[@OneMarcFifty]

The client will decide when to roam. 802.11r makes the roaming faster as it avoids key re-negotiations. 802.11k would accelerate further as it would maintain and publish a list of potential APs to roam to. Either way the device should start roaming before the signal gets really bad. But it depends on the client.

[@aakashmaroti1891]

@@OneMarcFifty Super! How hard will it be to get 802.11k also in the mix? additionally does it require some special hardware or are most wifi routers and clients compatible? Also, thanks a lot! This saved me a lot of unnecessary purchases!

First of all, THANK YOU so much for your videos! Not only they’re instructional and precise, but also engaging, simple to follow, and the fact you include chapters is great for coming back to them for future reference and follow along. Now, to the topic at hand, yes, I’ve been using a mesh since I moved from a single all-in-one modem/router/switch/WiFiAP to a Google Nest set with two satellites. Then, as I was willing to upgrade from AC to AX speeds, I swapped to TP-link Deco set, with three X60 nodes. Their performance is OK (definitely an improvement over Google’s Nest’s) but I just HATE they can only be configured via a phone app, with just a flimsy, stripped-down web portal! I’ll see if OpenWRT or pfsense are compatible with the Decos and let you know how it goes. I do think I’ll try B.A.T.M.A.N. because I live in a rental property, where I simply can’t get wires in a proper fashion.

[@OneMarcFifty]

Hi Bernie, awesome feedback, many thanks. Let me know how you get along with this ;-)

[@Yutaro-Yoshii]

I once tried re-purposing an old router as an access point in my home (tldr, didn't work). I kept the OEM firmware and just changed the password to match the main router/AP. But this didn't work because as mentioned in the video, devices hang onto the APs even when it gets faraway. Next we tried installing a mesh router with an attached repeated. This also did next to nothing to improve the connectivity. In the end, we ended up changing the provider and bought a big router/AP, and now everything works smoothly. The fight may have been long, but in the end, I got many spare network hardwares to play with (and do experiments installing openwrt etc), so I'm not complaining.

[@OneMarcFifty]

Many thanks for your feedback ;-)

[@federicosirica3696]

Thank you! Good advices! I've also noticed that when I test the internet speed with iperf3 between 2 PCs on the LAN is important to specify the tcp window size (when using tcp for testing). If I don't set it to a larger value than the default one I can't reach full speed.

Using 2 routers means you're using double NAT, which can make some things more difficult. It also means you'll break IPv6, if your ISP provideds it. I put my cable modem into bridge mode and use pfSense for my firewall/router.

[@OneMarcFifty]

Hi James - yes, very true. IPv6 was actually the reason for me to change this. My ISPs Router wouldn't do Prefix Delegation on the LAN side. Unfortunately I could not put it into bridge mode, so I had to buy a DSL modem. Since then I use a VIGOR 166 modem and it works like a charm.

[@Mentaloow]

You don't need double NAT.. you just need to configure OSPF or BGP.. then no need for NAT until your internet gateway.

[@James_Knott]

@@Mentaloow I doubt most users are capable of setting up OSPF or BGP, if they've even heard of them. I have my CCNA and never had a need to do that, though my router/firewall (pfSense) supports them and I also have a Cisco router here.

Hello Mark. Great explanation. Could you explain how you positioned your APs especially the 70 / 8db and how you came by the information.

[@OneMarcFifty]

I positioned one of each on each floor of the house. I tried to position them in the middle of the house with all antennas upright in order to have a sphere covered parallel to the floor. The info is from reading whitepapers from Apple and Microsoft - I just googled for it 😉

[@stephenbutler3105]

One more question. I noticed that you don't use the WAN port, and that the OpenWrt dump AP article seemed to indicate not to use it. Correct me if I am wrong, but this is simply because by default that port is not bridged with the LAN in the switch. I mean I believe there is nothing stopping us from using the WAN port in a dump AP configuration if we set it to untagged on VLAN 1. In my dumb APs I have deleted the WAN interfaces as I won't need them. The main router handles the WAN. So I assumed you can bring the port back into the LAN switch to provide another physical interface that could be used.

[@OneMarcFifty]

Your assumption is correct. It’s just a port on the switch like all others.

[@BradleeEdmondson]

Great video! Can you explain more about why you chose FT over the air, as opposed to FT over DS?

[@OneMarcFifty]

Hi Bradlee, short answer: I didn't see any roaming improvement with FT/DS and it worked with FT/OTA ;-) Long answer: Initially I set this up for FT/DS but I couldn't see any improvements in roaming time. Checking the logs on the router I got error messages saying the preauthentication did not work. When I switched to FT/OTA all of a sudden things worked. Digging a bit deeper I could not find the corresponding parts of the source code as the relevant commits on git were more related to passing the parameters to hostapd. git.openwrt.org/?p=openwrt%2Fopenwrt.git&a=search&h=HEAD&st=commit&s=802.11r for example. In a nutshell, with FT/DS the necessary FT information would pass over the cable from the old to the new Access point while with OTA it is negotiated between the client and the new AP. I might dig a bit deeper into this in the future but unfortunately many articles on the web are very Cisco-ish so I think I would need to have a look into the hostapd/wpad source code in order to fully understand how this is meant to work rather than just try and error. I have a couple of ideas though such as FT/DS might not work properly if the 1st AP is already out of sight plus I would need to maybe Wireshark the communication between AP1, STA and AP2. But as I said - once it was working I did not really dig deeper.

[@BradleeEdmondson]

@@OneMarcFifty Awesome answer, thank you! I also found lots of the easily searchable content on this to be Cisco-specific, so I'm glad it's not just me. In any event, I switched over to FT-OTA and it seems like roams have been going fine in my small two-AP OpenWRT environment. Thanks!

I was fine one network but with kids bringing school hardware home and friends, i want to keep them off the LAN.

[@OneMarcFifty]

Thank you for your feed-back J B. It's going to be a tough call in your config scenario as your AP is "AP only" ("dumb") - hence you can't do the firewall stuff on the AP but in your case it's presumably going to happen on the pfSense. Now in order to mirror LAN/Guest etc. config from pfSense to OpenWrt you will have to use VLANs or multiple wires, i.e. define the firewall zones in pfSense, assign interfaces with different VLAN IDs to each zone, tag them out to the AP and from there map them to SSIDs. I will deliver two videos (Firewall with OpenWrt, Guest Wifi) that will cover these, but presumably not with pfSense. If you want to talk this through, feel free to join my discord server - I am doing Video chats Sundays at 9AM and 6PM Berlin time and we can go through it.

[@OneMarcFifty]

Hi Amin, it is possible to connect routers Wi-Fi only - that would be a Mesh. I am still thinking if I should do an episode on this or not - real Meshes ( I mean other than just repeaters) IMHO only make sense for many nodes. You can't use the suggested config here and just add a Wifi Backbone. That's not possible because you can't bridge Wifi in STA mode. w/r to the capabilities - if you run "iw list" in a termina and the capabilities list "mesh point" then you have good chances that 82.11r is supported, even if the two are not directly related - just an experience.

Hi, this could be doable with stock firmware but it depends on a lot of factors (brand, model, etc...) - fast transition just accelerates roaming - simple AP operation would work as well, just roaming would be slower or not occuring if you want it to.

Finally I found someone who mentioned that a Pi will never be a good access point because it doesn't have built in networking hardware. Then I got an EspressoBIN but that was also challenging. One of he R,Pi's finally died. So I just recently got a couple Alfa WiFi access poits and after a few long days over two weekends I got OpenWrt loaded on them. I haven't setup 802.11s yet, I'm enjoying the improved WiFi so much. Also I don't want to experiment with the WiFi that I'm currently using. So I bought a pair of Ubiquity AP AC PRO Gen 2 access points and I'm working on getting OpenWrt loaded on them and I plan to test out 802.11s and batman-adv on them first.

Hi Josiah, many thanks for the feedback ! You might want to try the luci interface that I have submitted to the OpenWrt LuCI project: github.com/openwrt/luci/pull/5698

[@albert-janscholtalbers3529]

It works . It seems you only use LAN side of dumb ap. Do you have example to use WAN (Internet) as upstream, so on an R7800 you can use Internet, p1,p2,p3 and p4 and Wifi?

[@OneMarcFifty]

Hi, you can assign the wan port to any interface just like any other port. On some hardware in the switch menu, on some hardware with OpenWrt >=21 with DSA

[@briancoverstone4042]

I use a VLAN attribute through a radius server to tag each wifi client with a separate VLAN. Unfortunately, the fast roaming doesn't seem to work properly for these clients. I'm wondering if I might be setting something up incorrectly?

Hi Brian, difficult to say without knowing the details. Maybe join the discord server and describe the situation in detail there ?

[@arunkhan4951]

@OneMarcFifty Great video ❤ it. Excellent point on disabling dhcp, dns on the dumb APs before adding the AP device to the network 😅 Please clarify a couple of things 1. How are the "dumb" APs connected to the gateway device, Ethernet cable hub, and spoke topology? I have followed the hub and spoke (Ethernet wired) and enabled Wi-Fi fast roaming. The setup works like a champ. But I would like to hear your thoughts. 2. Are Wi-Fi fast roaming and Wi-Fi mesh mutually exclusive? Do one or the other. 3. For dwellings where running Ethernet cables to the dumb APs is not feasible, what's the best way to achieve Wi-Fi coverage in all the corners of the dwelling. 4. Apart from Linssid (desktop), what app would you suggest for mobile devices (Android and iOS) ?

[@jurczykpawel]

Hi, could you please advise if both networks (2,4 and 5 g) should have the exact same configuration? I mean config related to 802.11r Fast Transition and DTIM Interval?

[@OneMarcFifty]

I have configured both the same way w/r to Fast Transition, i.e. I can roam between the two. I have not yet investigated further w/r to DTIM. I assume you could set those to different values and maybe nicely "advise" a client to roam back from 2.4 to 5 GHZ if the 5GHz signal gets stronger. But as a next step we will try and do that with 802.11k and 802.11v.

[@andrewbezzina87]

I think its important to mention that not all clients support 802.11r. I have been doing some research and found the for example all macbooks (except the latest with apple silicon) don't support it. I am afraid that this could cause issue for me if enable it, I just bought an Archer A7 to go with my C7 but now I am having second thoughts and wonder if going with mesh instead will be better. I wonder if anyone else has more experience regarding this.

[@OneMarcFifty]

Hi Andrew. A mesh is just a connection of Access points over Wi-Fi. the Fast Roaming is a feature that you can use over a mesh or over a wired solution like the one shown in this video. If you can use Wire then prefer it - it's better. Usually laptops, phones etc. have no problem if the AP provides Fast roaming. Some Micro Controller devices do however. For this I'd suggest using a separate IOT SSID without Fast Roaming.

[@andrewbezzina87]

@@OneMarcFifty thanks for the advice. Do you think it could be worth using different SSIDs on the 2 routers but on the same mobility domain to still have fast roaming but also the ability to force which router to connect too if the device does not transition automatically?

[@remkm1715]

@OneMarcFifty I was just looking for this. the moment i enable 802.11r Fast Transition My Macbook air M1 does NOT want to connect to the AP. I am in dire need for FT im my house though. love to hear solutions to try. love your channel.

I have 1G ISP fiber with static public IP. I would like to have many hardwired APs in a large house. What are tradeoffs within the same budget? AC vs AX, mimo 2x2, 3x3, 4x4? Or just maximize number of APs sticking to the cheapest devices providing AC1200+1G eth+ openwrt?

[@OneMarcFifty]

Hi Tomek, first I'd ask myself the question what I would prefer and/or try to achieve. Is it better coverage of Wi-fi in the corners of the house ? Or is it maximizing the bandwidth for one user ? Or better usage for many clients ? First case - add a bunch of cheap APs and spread them everywhere. Second use case - go for a powerfull AX AP. Third use case - add a small number of AX APs. Plus of course see if everyone needs to be on the same SSID etc.

[@tomeks666]

@@OneMarcFiftymy experience so far is that even a relatively cheap AC1200 router can put through +900mbits as long as you are connected to it with 1g ethernet. At the same time it it hard to get speetest over 600 through wifi even standing 1 meter from the router on wireless. WLAN speed goes down very quickly with the distance. I would just like to get a feel of 1GB regardless of which part of the house I am in. For now I am testing many cheap access points connected with 1gb eth. I do not know what would happen if I used a powerful router instead, but aren't powerful routers constrained with the same transmit power limitations as the cheap once? What does it actually mean powerfull?

[@OneMarcFifty]

Usually people would describe a router to be more powerful if it has a stronger CPU. For your use case you would before anything else have a router with at least 4 antennas in the same band - so presumably a device with 6 or 8!antennas (preferably external)

[@fastjp72]

Does the 2Ghz & 5Ghz both have to be same protocol like N or can 2Ghz be N while 5Ghz is AC for the fast roaming with fall back between both frequencies? Thanks great video! 👍🤔

[@OneMarcFifty]

Hi, it should work with N/AC mixed but I haven't tested it.

[@pisanchez94]

I have the following scenario, I have a router that manages the entire lan with Mikrotik's RouterOS, it does not have WiFi (R1) and two access points with Open WRT, they are connected with cable, roaming works, or R1 must also necessarily run OpenWRT

[@helmanfrow]

Hi, I have a question not related to this video: My sister is using a proprietary router for the kids' Wi-Fi. I rather dislike it but the firmware makes it relatively easy to restrict and grant access to the kids' devices from a phone or computer using a browser interface or an app. Neither OpenWRT nor pfSense make this easy, even with extensions. I can get by using advanced firmwares but the other adults in my life cannot. Do you have a FOSS solution for EASY parental controls that normal people can use? I'm considering upgrading her to the Firewalla purple. Also proprietary but it seems more robust than what she's using now.

Hi Marc, thanks for sharing this video. I have been looking around to buy a good WiFi 6 router that can be setup in the way you showed in this video. I haven't been able to come across any good options. The newer ones don't seem to be supported on OpenWrt. Any recommendations on which routers I can go with that would support 802.11r? One thing interesting that I have noticed is that none of these routers support 802.11r. Seems like that is an option supported by OpenWrt's firmware but not by the default firmwares (?). I almost feel like I might need to buy those expensive enterprise routers. For context - I'm trying to setup WiFi across a 4-story house (~7000 sq.ft). The house is made of concrete walls.

[@OneMarcFifty]

Hi Varun, this table view of the OpenWrt ToH gives an overview of all Wifi 6 supported devices openwrt.org/toh/views/toh_available_16128_ax-wifi I have made good experience with the Belkin RT 3200, but I know people are using the Xiaomi AX 6000 more and more. At the moment it's snapshot though. For a larger house like yours you might need one for each floor though.

[@sergsqr]

Thank you very much for such comprehensive material, I have never used the 802.11.r standard before. I currently have three simple access points (DHCP and DNS on another device) in the 2.4 GHz band on channel 1 (40 MHz wide), channel 8 (20 MHz wide) and channel 10 (20 MHz wide). I have a delay of more than 2 seconds when switching from the first access point to any of the other two. Can you tell me how to improve it?

Hi great video and I bout several mi 1g and tp link 1975 routers to build a very large mesh. Can I ask if the fast roaming applies to open wit's mesh set up?

[@blucobalt8688]

Can the ssid be the same for 2.4ghz and 5ghz across both access points and fast transition still work between the bands and access points?

[@OneMarcFifty]

Great question ! Yes it can. I am actually doing this at home. the only problem is that if your client moves away from the AP then it will presumably roam to the 2.4 GHz. Once it gets back into the reach of the 5 GHz it would not automatically roam back. I really need to look at Band steering for this.

[@emenny81]

Your video was very helpful, I had some wifi problems and I decided on getting some HUAWEI ax3, the coverage is very good but I have tons of problems with HomeKit. These HUAWEI routers are very limited to a point you can’t even set your own dns server on the lan side. I don’t use the mesh portion of the ax3s I just have everything hard wired like you do. My question for you is mdns supported on openwrt? Since you have an iPhone do you have any HomeKit devices ? And if you do, do you have any problems connecting to your devices while being inside your home ? I keep getting the dreaded no response on multiple devices and it’s driving me nuts!!!

Thank you so much for your guide! I have bought Linksys EA7500V1 yesterday. And what I've noticed, that even this quite good router with ac and MU MIMO works almost the same as the cheap one from ISP. It's about just 55 Mbps even on 5 GHz on my xiaomi Mi 9 (it's sports ac) while I've got about 95 through the cable on the both routers. And what about the MESH - I've tried just Tenda shitboxes. They give about 30 Mbps from 300+ even when devices is very close to the shitbox, connected by the Ethernet.

[@OneMarcFifty]

Hey many thanks for the feedback and sharing your experience !

[@itsmith32]

By the way, OpenWRT firmware is much more better. Since installation I've increased wireless speed up to almost ISP maximum. Also it's allowing to use it with only 7 db signal power out of 100 which is much more better for the health.

Shouldn’t the antennas on each AP be oriented 90deg from each other so that they’re in different planes to prevent interference?

[@OneMarcFifty]

It really depends what plane in space you want to "illuminate" with Wifi. In my case each AP is on a different floor, so the planes will be the store of the house really. W/r to antennas on one single AP, they should all point to the same direction usually because either they are used to form a beam (in the case of MU-MIMO), and the interference between the antennas is actually used to achieve this. On older APs one antenna is set to receiving and one for sending.

[@multibatmam1]

Hi! First, I would like to thank you for this amazing video, it is very well divided and explained! I just have one question, in the configuration of the dumb APs, could I use a static IP adress instead of DHCP client (using the main router IP on the DNS and gateway of the dumb AP)?

[@archie591]

@OneMarcFifty thanks for the tutorial again! I was wondering if there is a specific router feature I need to look for to ensure this setup will work with any openwrt router? thanks again!

[@OneMarcFifty]

It's not really a listed feature (like when you run iw list) - like the 802.11s or beamforming etc. From what I can say is that the "usual" well supported drivers such as Mediatek or Atheros would most probably support it, i.e. if you stick to MT7516, MT7915, ath10k and the like then you should be fine.

Love the videos! I've got a main router Netgear R8000 running Shibby and 2 old WRT54G-TM's with Tomato-ND as APs for IoT devices.

Nice feature AddOn for a guest network: establish a wireguard client to a VPN service like azire, mullvad etc, and route the guest traffic over the VPN service. this must be done failsafe, so if VPN service is down any reason, guest network does not have WAN access. and of course, no access to other zones or router services.

Hi sir Marc. Thank you for your very educated video. I just had few questions and quite controversial did you research if wifi is safe for us? Is it not cancerous? I see some routers settings like in Ruijie saying Health mode and when I clicked the description it will just lower the transmission power of the wifi. Do you think will all wifi bandwith safe 2.4Ghz, 5Ghz and the future 7Ghz? Thank you

[@OneMarcFifty]

Hi Mark, I am afraid that I can't really answer that question. It is true that the total amount of radiation that we get with Wi-fi, Cell phones, Microwaves etc. may be considered concerning. I do not know to what extend. However - reducing the power on your Wi-fi might also be a good idea with regards to better Wi-fi coverage. It is actually better to have overlapping low-power cells than just one mega-boosted Access point if you have multiple Wi-fi clients. In that perspective, Fast roaming can actually help you reduce the transmit power of one single station.

[@markpelayo]

​ @OneMarcFifty Wow I really appreciate your lengthy and juicy reply. Thank you sir Mark! I'll take note of that many low power rather than 1 single high power wifi.

Hi Andrei, not really - you would never be connected to two APs at the same time, nor would an AP connect to Wi-fi of another AP. Loopbacks happen when you have more than one way of getting from A to B which is not the case in this setup.

Can this be implemented on a AP which broadcast multiple SSIDs(VLANs)? I have a TL-WA1201 to cover my entire house, but there are weak spots that want to improve. I don’t want to use a mesh system because of the price and because I have segmented my network in 3 different VLANs (main, IoT and guest networks).

Hi, absolutely. That's one of the main benefits when you use VLANs. You would just have to define the interfaces on the AP and map the different SSIDs to the corresponding interface (which in turn is tied to one of the VLANs)

The only thing this configuration doesn't give you is centralized control over all the APs which is important if you need to have a separate kids' network that can be quickly and easily shut on and off. But I asked about this on the OpenWRT forum and someone suggested creating a separate network and SSID for the kids and managing access control using VLANs and firewall rules. It's a little complicated for the normie adults in the house but I'll give it a shot. The ideal solution would provide independent access control for individual devices, but that's hard to do outside of something like Unifi / Omada / etc.
