I have separate router and access point. I set up my guest WiFi with a 2nd SSID on the AP and used a VLAN to carry the guest traffic to my router over the same cable as my main WiFi. My router is pfSense running on a mini PC. I prefer this configuration, as it's more flexible. For example, I could have more than one AP. Also, most access points support Power over Ethernet (PoE) so that you don't need to have AC power handy, so you can position the AP for best coverage.

One other advantage of a guest network - they can be run at a lower (maybe obsolescent?) level of Wi-Fi security. As an example, my Eufy robot vacuum won't connect to my main network, but connects AOK to the guest network on my TP-Link access point.

This is the first time I have watched your videos and I have to say that I have never before, nowhere, found such a structured and informative speech! Congratulations!!! However, I wanted to ask a question about the security and the difference between these two networks (Basic and Guest). These two networks, do they not belong to the same transmission domain? Do they receive from the same address domain? From the same DHCP Server? How is the Basic WIFI network secure from the Guest WIFI? Since they belong to the same address space, i.e. the same LAN. Couldn't a malicious user still negatively affect the other computers belonging to the Basic WIFI? I apologize if the question is funny, I am in a beginner stage and trying to understand how the whole process works. Thanks a lot in advance!!! Keep up the good work! 😁

[@JJFlores197]

There's something called VLAN (Virtual LAN). When you enable a guest wifi, your router automatically creates a separate virtual network and creates firewall rules that prevent that guest network from communicating with your main network and vice versa. The DHCP server portion of your router is also configured to assign guest devices IP addresses from a different pool of addresses.

Another thing to put up is time limits. Very important thing I wished you touched upon. For example, you can set the guest network to be active only when you want it to, like from 1pm to 7pm, Monday to Friday. So outside of those hours nobody can touch your net.

Question, so I have an ASUS router, and they have a dedicated tab for 'Guest Network' however in a separate tab called 'Wireless' I can also add multiple 2.4GHz networks.

Just wondering whether setting up Guest Network will affect my network speed and latency and power consumption.

[@user-pe8mv2yi7l]

depending on the allocated bandwidth to such guest, if u set up a limit or upgrade your main you’ll be less likely to experience latency

[@cuspajzz]

Off course it will affect your speed because any WiFi network that you create on you router use/ share same bandwidth that ISP alocated to you. How much that is another story as @user-pe8mv2yi7l stated that depends on the allocated bandwidth to such guest network/ client plus how many guest clinets are conected and how many simultaniesly use max alocateted bandwith per network/ client.

[@weekendwarrior3420]

When I give my info to Aura, it's yet another entity who now has it. Then they can sell it as any other and not be accountable because, well, we know that many entities have this info, so it's impossible to know who sold it. And even if it doesn't, unless you exterminate your info simultaneously everywhere, it'll spread back, as weeds spread in the garden. So what's the point of Aura?

[@alap1983]

There's one more important use for the GUEST WiFi Network. Set the Guest WiFi to 2.4Ghz or 802.11b/g/n. Keep the security protocol or authentication to AES. Connect all IoT devices such as Smart Hubs, Smart Bulbs, etc to this Guest WiFi. This will isolate all these internet-enabled devices and keep them separate from the Home WiFi Network.

[@SlipperyBannana]

Can you explain this more? Why does it have to be 2.4?

[@alap1983]

@@SlipperyBannana Most iOT devices need VERY LITTLE bandwidth. Moreover, they are scattered throughout the house/office. The 2.4GHz network has good reach compared to the 5GHz. Moreover, ALL IoT devices that can work with WiFi work with 2.4GHz. This is to ensure reliability and compatibility.

Is it possible to isolate a 2nd router as a guess network so that guest can connect both wired and wireless?thank you! ☺️

[@JJFlores197]

I suppose you can, but it requires configuring a port on your main router so that all traffic coming from that port is only on the guest network. How you do this and if its possible depends on the router in question.

[@MrPir84free]

I have not seen that feature yet implemented any commercially available consumer wifi router; It can be with a home built system, but if a "guest" can select which port to plug into, well, so much for security.

[@h5_9n]

Thnx bro I've a question: If i made a guest wifi, will that affect my primary wifi, whether speed will be shared or something ? For example, if i just enabled the guest wifi without any device connected to this wifi, would that split the speed of my primary Wi-Fi

[@JJFlores197]

There won't be any performance loss by having the guest network enabled AND that there are no guests connected to it. If you have a lot of guests on the guest network, it will slow down your internet connection, but you can usually set speed restrictions on your guest network.

[@sairamkandukuri3412]

could you please make a video on Load balancer..?

[@wannabedal-adx458]

You said the router uses the same rules as a firewall to separate your personal network from the guest network. But I always thought of it like a VLAN. Am I wrong? Thanks!

[@JJFlores197]

VLANs and firewall rules generally go hand-in hand. You can configure your firewall to allow the guest VLAN, for instance, to talk to your main network. Or you can configure it so that they are isolated. Or you can configure it so that only a device inside of the home network can talk to the guest VLAN, but not the other way around.

[@MrPir84free]

Most consumer grade wifi routers that are out there run everything on a single subnet. As you get into more advanced setups, usually using a Wireless Access Point(s), well many of those will use VLAN's with separate subnets, different settings for each channel . So, not wrong, but not right in most cases..

Is there anything wrong????

[@JJFlores197]

You may need to configure firewall rules to prevent your guest network from communicating with the main network. Its my understanding that a guest mode automatically does that for you. But you may need to read the documentation for your router. I also believe that guest isolation is only used for wifi. In other words, if you have multiple devices on wifi on the guest network AND guest isolation is enabled, those devices won't be able to talk to each other.

[@MrPir84free]

Most guest networks can't ping other devices and devices on the primary wifi network. However, it's quite common for a device on the primary network to be able to ping and actually initiate communications with a device on the guest network. Some IOT devices require such, and it's built into a lot of consumer wifi routers.

[@phoneguy1015]

Are the 2 networks on different subnets?

[@MrPir84free]

That depends upon the setup; on most routers with the guest functionality, NO, the IP subnets are one and the same. On better devices, which is usually based upon VLAN's, YES.

[@user-ov1ly8bb1n]

[@karlstenator]

Hmm ,so when my Fridge or Vacuum cleaner come with wifi options... maybe it's best to sign them into the Guest network?

[@PowerCertAnimatedVideos]

No, that's not necessary.

[@MrPir84free]

Generally speaking, if the device requires internet access, yes. If the device needs to access the home network, for things like accessing a NAS, then perhaps not. The problem with MANY IOT devices is that your fridge or vacuum cleaner will NEVER get firmware updates, bug updates, software patches, and the like. So, in many cases, these devices should be on a separate network, isolated from each other. Most IOT devices are also WPA2, which has some vulnerabilities, so another reason to leave such devices, if possible, on a guest network. Consider them as UNTRUSTED devices. Although not covered directly, you should not use easily cracked passwords, use complex passwords instead, rather long as tolerable, and completely different than what is on the primary wifi networks. WPA3 should be the aim for your primary network. It's becoming more common to have a primary wifi network, a secondary wifi network for more susceptible devices, a guest network, and even a separate IOT network. I currently only use 3; a primary that is WPA3 only; a secondary guest that is WPA3/WPA2 which is for phones and work from home laptops/etc, and a third IOT which is 2.4ghz only WPA2 only. Each has its own name and each has its own unique long password.

[@interproservice]

But when you share your password who is responsible when one of your guests commit a crime using your network? It will make serious problems for the owner.

[@JJFlores197]

Well at that point if you can't trust your guests you have bigger issues.

[@MrPir84free]

A few things: 1. Technically- YES, you might be implicated; but in reality, who did the crime ? 2. Once configured, often the settings are never removed from the device meaning that the device has access effectively for life. It's probably a good idea to change your password for your guest network shortly after every use. That should stop the leeches... 3. You could eliminate some of these concerns by pushing the guest network out a VPN connection to somewhere else; VPN services with No Logging exists and are pretty common. It's not typical on most consumer wifi routers. It can be done though !!! My favorite guest network setup was a wide open network I configured back around circa 2005; the wifi was routed thru a m0n0wall router with a captive portal; I'd literally assign a username and password for access, which they'd need to use, and I could set an expiration date and time after which they could no longer use the wifi.. m0n0wall is no longer available I believe. But it ran for several years on an old white box Dell workstation, as a vm on XP (? ).
