Use Second Router As Guest Network

Many home routers offer a "Guest Mode." This isolates your guests onto a separate Wi-Fi network, and y'all don't have to requite them your normal Wi-FI passphrase. But Guest Style is ofttimes insecure.

Guest Way isn't ever bad — D-Link, Netgear, and ASUS router seem to do information technology correct. Merely, if you take the type of Guest Manner we've seen on home routers from Linksys and Belkin, yous should never utilize information technology.

Why Guest Mode?

In theory, Invitee Mode is a fine idea. Rather than having guests connect to your normal Wi-FI networks, a router with Guest Mode volition host multiple Wi-Fi networks. Guests who visit your home tin can connect to the guest network, which can have a separate passphrase from your normal Wi-Fi network.

This allows you lot to keep your normal Wi-Fi network individual. It also keeps guests from accessing your network file shares and other sensitive data. Even if they're feeling snoopy or have malware installed, all those guest devices will be isolated from your normal Wi-Fi network.

Rather than gaining access to your entire network, devices connected to the Guest Network only get access to the Cyberspace. Guest Mode settings may also allow you lot to limit the number of devices that can connect to the guest network. So far, this is fine.

The issues are immediately obvious when you enable guest mode, or when you connect to a network configured for Guest Mode. Y'all'll see that the separate guest network is probable an open Wi-Fi network. In other words, it'south not protected by the normal Wi-Fi encryption that secures your main network.

This means that any network traffic travelling over the guest network is sent "in the clear," and is vulnerable to snooping. It's just like connecting to a typical hotel's Wi-Fi network. The connectedness is unencrypted, and anyone nearby tin snoop. Modern operating systems volition fifty-fifty warn you about this when yous connect.

But there is a password that guards admission to the Net. After a device connects to the Guest Way network, it sees a login page. The user has to provide a passphrase or the device doesn't get Internet access.

This provides more protection than hosting a typical open Wi-Fi network, but not by much. The Wi-Fi login page is generally unencrypted — you can tell because in that location's no HTTPS or lock icon on the address bar. If you connect to the guest network and provide the password, it's besides sent unencrypted to your router. Anyone snooping on Wi-Fi traffic nearby can clearly see the Guest Mode countersign every time information technology'due south typed in, and they could use it to access your guest mode network without your permission.

The default Guest Mode countersign on Linksys routers seem to be "BeMyGuest", which is besides insecure — many people will utilize Guest Mode without changing this.

How Some Routers Offer Secure Invitee Modes

Some router manufacturers avoid this problem by actually using normal Wi-Fi encryption in guest mode. All they have to practice is host an entirely split Wi-Fi network with the typical encryption — generally WPA2 encryption — that you should be using on your main Wi-Fi network.

We've seen D-Link, Netgear, and ASUS routers provide proper guest networks in this way. They create a separate, encrypted Wi-Fi network and isolate information technology from the main network. The most important thing is that encryption is available.

To examination whether it's safe or not, merely enable Invitee Way on your router. Try to connect and see whether information technology's an open Wi-Fi network that allows yous to connect instantly, or a closed Wi-Fi network that your operating system requires as passphrase for before connecting. If you run across an operating system password dialog, information technology's secure. If a web browser pops up and asks for a password, it'due south insecure.

Guest Mode is a nice idea, but it's far from completely necessary. If you want to utilise Guest Mode, be sure that your router offers a secure encrypted invitee network — not an open, unencrypted one. With an open guest network, your guests could have their Wi-Fi usage snooped on and your Guest Way passphrase could be easily eavesdropped on and captured, assuasive anyone nearby to proceeds admission to your Net connectedness.
