00:00:00.000 --> 00:00:04.080
So you're hosting a party and your guests all need Wi-Fi because even though the point of

00:00:04.080 --> 00:00:08.560
having them over is to socialize, they still can't be separated from TikTok for more than five minutes.

00:00:08.560 --> 00:00:12.560
And before they arrived, you were fiddling with your router settings because you're a cool kid

00:00:12.560 --> 00:00:18.000
like me and you saw an option called enable guest network. So what does that setting do

00:00:18.000 --> 00:00:22.720
and is it designed for occasions just like this? I think it might be. The main point of a guest

00:00:22.720 --> 00:00:27.360
network is pretty straightforward. It allows anyone connected to it to access the internet,

00:00:27.440 --> 00:00:31.520
but prevents them from accessing any other devices on your network.

00:00:31.520 --> 00:00:35.760
So no need to worry about your guests printing out rude messages like they usually do.

00:00:35.760 --> 00:00:39.760
But how exactly does your router keep your guests away from your stuff?

00:00:39.760 --> 00:00:43.840
Pretty much every router out there uses internal software rules to determine

00:00:43.840 --> 00:00:49.520
what network traffic can get sent where. A guest network is usually a different sub network,

00:00:49.520 --> 00:00:54.000
sometimes on a different virtual LAN, from what the rest of your devices live on.

00:00:54.080 --> 00:00:58.000
After your router sets up the subnet and possibly a VLAN for your guests,

00:00:58.000 --> 00:01:03.120
it simply enables a rule forbidding traffic from the guest network to your main network.

00:01:03.120 --> 00:01:06.880
Most consumer grade routers don't require you to go fiddling around with things like

00:01:06.880 --> 00:01:12.400
rules and subnets and VLANs on your own. Just click enable guest network and it takes care of

00:01:12.400 --> 00:01:17.120
all that in the background for you. It's so nice. Typically, once you enable the guest network,

00:01:17.120 --> 00:01:22.480
your router will start broadcasting another SSID, that name you see in the list of Wi-Fi networks

00:01:22.480 --> 00:01:26.400
on your computer or phone that will make it obvious that it's what your guests should be

00:01:26.400 --> 00:01:30.800
connecting to. But you can always change it to whatever you'd like. Maybe something a little

00:01:30.800 --> 00:01:35.280
sassy. You might assume that it's all right to leave your guest network open so visitors don't

00:01:35.280 --> 00:01:39.760
have to go through the rigmarole of punching in a password. After all, the traffic going over

00:01:39.760 --> 00:01:44.560
the guest network can affect your main network. So what's the point? Well, there are a couple of

00:01:44.560 --> 00:01:49.600
huge points, actually. One is that without a password, any stranger that's close enough to your

00:01:49.600 --> 00:01:54.480
router, say if the signal extends outside your house, can connect and do god knows what over

00:01:54.480 --> 00:01:59.440
the internet, which could be traced back to you if it's illegal. But even if that doesn't happen,

00:01:59.440 --> 00:02:03.520
not having a password could leave your guests open to having some of their internet activity

00:02:03.520 --> 00:02:09.360
spied upon or their data stolen as someone nearby could easily see any unencrypted data sent over

00:02:09.360 --> 00:02:14.480
an open guest network. Don't take these risks, assign a password, and if you want to make things

00:02:14.480 --> 00:02:19.440
simple on your guests, you can even generate a QR code with free online tools that you can print

00:02:19.520 --> 00:02:24.080
out and folks can just scan it to join your password protected guest network without a bunch

00:02:24.080 --> 00:02:29.760
of hassle, which will definitely make your party an official cool kid party. The other big thing

00:02:29.760 --> 00:02:35.120
we want you to know about is a common limitation of the guest network. What if you want a guest

00:02:35.120 --> 00:02:39.440
to be able to access part of your home network? This can be a real issue if someone just wants

00:02:39.440 --> 00:02:44.320
to throw a video up on your TV using Chromecast, or if folks are trying to game with each other

00:02:44.320 --> 00:02:50.400
over Wi-Fi, especially as guest networks usually also prevent guest clients from even seeing each

00:02:50.400 --> 00:02:54.640
other. In these situations, you'll likely need to do some more advanced configuration if your

00:02:54.640 --> 00:02:59.840
router allows it or just give your guest access to your main network. Hopefully you've made friends

00:02:59.840 --> 00:03:04.160
you can actually trust. And I knew I could trust you to finish this video. Thanks for watching.
