OpenWRT - Bandwidth Limiting for LAN & WiFi - SQM QoS

[@AntonPopov_]

Hi, great content! As I was watching the video and especially the end I think a video on Firewall rules would be very interesting. I know you mention there's a lot of topics suggested but you speak a lot of vlans or just different LANs and having proper isolation between them would be nice follow up.

[@VanTechCorner]

Yup soon I will make a video about VLAN isolation/ Guest WiFi. (by right device from different shouldn't be able to communicate with each other but I don't know why they can on OpenWRT)

[@pcpc-r1c]

I understand it correctly, using this qos i can set up speeds for each ports ? Similar than mikrotik simple qoe and bridges ?

[@blaichan5689]

What is your router model and what is your recommendations the best budget router wich include usb port. Thank

[@osst12]

So, for file sharing between pcs, will I get full gigabit from my gigabit router by setting speed to 0 with sqm. My router isn't powerful enough. And turn on sqm, say 100mbps, for certain ports and wireless device which the router can handle?

[@VanTechCorner]

Hi, SQM will just help to prioritize/control the traffic. Your router should be able to handle Gigabit througput first.

[@epic1hit]

can you make a video how to use SQM AutoRate plz

[@ruslan_voyager]

Why did you create lan-unterface if f.e. device is already connected to lan2, why not just to use existing lan2 interface? Why did you assign new ip for new interface if it connects to wan anyway? I made this settings as you described in video but in the end there is no internet on other lan ports except lan1 and I cannot connect to devices by ssh from pc(which is on lan1 port).

[@VanTechCorner]

Actually I have answered your questions in the video, it is at 10:28. You mentioned that LAN 2 has no internet, does it received the IP address from the new DHCP server?

[@ruslan_voyager]

​@@VanTechCorner Ok, I see, I didn't have to create additional interface, and also I just had to restart sqm service after creating rules. I have a question if I have to set "fq_codel"(which is by default) or "cake" in "Queue Discipline", is there any difference?

[@VanTechCorner]

You can watch the previous video "SQM QoS" where we talk about the basic concept of SQM. The default value, cake and piece_of_cake.qos would be good enough to go with. If want to know about difference, here is the technical document that can help with openwrt.org/docs/guide-user/network/traffic-shaping/sqm-details

[@anshraj5916]

you are a god from india

[@tristanjsa]

Hi man, first of all want to thank you for making these vids on OpenWRT tutorials, they're really helping me out! I wanted to ask if I need to change the settings for Queue Discipline and Link Layer Adaptation tabs on SQM to that of the same settings I put on my WAN SQM instance? Or in other words, do I need to change those tabs at all (like change default fq_codel to cake again and such), or just leave it as is?

[@porkbelly872]

Use cake and piece of cake if possible. You get better distribution of bandwidth among the users in that particular interface. Fq_codel falls apart in terms of per host fairness when one user starts torrents or a large steam downloads that opens up a lot of connections. You should be okay to leave others as it is.

[@ofiefrahmad6963]

please make a video how to limit the bandwidth of each IP or Mac in Openwet? ,

[@cabonk3273]

Hi ,i do follow your configuration on the dumb ap. Now im wondering what do i need to setup if i dont want all devices connected on the NORMAL SPEED LAN to access the login dashboard but all networks connected in the high speed lan will be able to open the login dashboard

[@VanTechCorner]

Setup guest / 2nd LAN and set the limit for the interface with sqm qos, and limit access to LuCI with firewall rule. Just like what I did for guest network.

[@ramiaddas1437]

can you apply rate limiting based on MAC address of the wireless client instead of vlan and interfaces ? all my clients are wireless clients and i dont want one wireless client to take all the router bandwidth which will make the connection slow for other wireless clients.

[@VanTechCorner]

Hi, I got your question and will take a look on this!

[@king4053]

​@@VanTechCorner I think with NFT QoS it's possible and good for huge number of users because I think you can assign a bandwidth on a range of IPs using CIDR. I haven't really looked up into it though because I've read somewhere that it has compatibility issues running with alongside with SQM which I prefer for it's automatic handling and lower latency.

[@kajape2967]

Hi can we create also a bandwidth per port in newifi

[@VanTechCorner]

Yes, basically you just need to create different interface with different port (either using the switch page or manually assign it), and then set the limit qith SQM QoS.

[@diegofenner1333]

Hi mate. Could you please explain on another video how to create a time schedule bandwidth limit for a LAN client? Example: limit phone speed at night.

[@oussverde]

interesting and interested

[@j0efil]

Hi, this a great tutorial very easy to follow. However, this only limit the bandwidth per Interface. Do you have a way how to limit the bandwidth per IP or per Client? Thanks!

[@VanTechCorner]

Hi, you can take a look at this, there is example available openwrt.org/docs/guide-user/network/traffic-shaping/packet.scheduler#examples

Bác có thể làm video hướng dẫn cài đặt và test sqm-autorate trên mạng LTE được không, rất cảm ơn bác.

[@kakangbagus1536]

SQM don't work after reboot, how to fix?

[@VanTechCorner]

Hi, did you fix it? If not, please check if you enable the SQM on the Start up Tab?

[@XemmanX1]

sir please i need help why when i speedtest using my phone in my wifi i have high ping in my pc ? but when my pc speed test my ping is too low ? how to fix this ?

[@VanTechCorner]

We can assume that the high latency caused by wireless connection, either by your phone or your WiFi router. Try with another the phone and if the ping is still high, it is something wrong with the AP of the router and you will need to work on this.

hi bosku..Mi 4a Gigabit router+firmware openwrt, how to setup limit speed other user connected on wifi? tq from sabah..

Hey, I got your question on the group.

[@kennynugraha]

Very Helpful video! but i was wondering how to limit bandwidth per ip address by using SSH Command? what i mean how can we configure it by using ssh command not by using luci GUI?

[@VanTechCorner]

Hello, we have the list of SQM config values. You can check it out here openwrt.org/docs/guide-user/network/traffic-shaping/sqm_configuration

[@AndyBaedal]

Hi Van Tech, thanks for a very informative video for a beginner openwrt user like me. I have a question, what if we want to setting bandwidth with minimum speed instead of maximum speed? E.g: total bandwidth that is available: 30 down + 15 up. - Setup for main ssid: minimum 20 down + minimum 10 up. - Setup for second ssid: unlimited. (So the idea is the second ssid will getting the reduced speed only whenever somebody using the main ssid) Is it possible?

[@NicolasMorais]

Yes, it's possible. QoS has many specific settings, and I'm sure that one of them will meet your needs.

[@YORDANSERGEEV]

How can I contact you in personal message. I want some one like you that knows these things to help me out with my cudy router... I can`t manage it on my own... if you need to be payed I`m up for it... just to get this router to work.

Мне очень жаль, но я не понял, как ты понизил скорость wi-fi

[@VanTechCorner]

Tak farham Malayu bro. I guess you are asking about install OpenWRT on DLink 842-C2, right. Sooner there will be a video ;)

[@mohdasri4736]

@@VanTechCorner yes right

[@ViperSTR]

Unfortunately, openwrt reduces the internet speed on the router, if it is on a router or a factory operating system, it is full speed and we have a lot of problems that you cannot receive full speed on openwrt. The speed on the router is 980Mbit, but on the same router with openwrt 400-500Mbit! !! Why should it be like this?😨

[@VanTechCorner]

Is it after you enable SQM QoS, or before? Did you enable software offloading on the Firewall? Can I have the model of the router?

[@martingregson7136]

What your videos should say is "only watch if you are an expert and already know what you're doing!!!" For god sake man simplify them stop with the acronyms they are confusing most people don't know what they stand for and put off viewers

[@VanTechCorner]

Not really on expert level, but one should have at least basic understanding about OpenWRT before they want to configure advance stuff, either with LuCI or CLI. Most of my videos are based on the official document from openwrt.org and the URL is available at the video description.
