router security using guest access

My Linksys e1500 router has a guest access feature that I like using for times when I have visitors wanting to access the internet using their own devices (IPad). I have mine set up to allow only one guest at a time. Otherwise I could allow up to 10.

My question, is there any way you are more vulnerable leaving your guest access on when not in use?

The Guest network is a virtual network within your private network because it operates on a different IP address range (192.168.33.x). This allows your guests to connect to the Internet without becoming a part of your private network.

FWIW I have a ZyXEL NBG334W wireless router with a guest wireless network. In my case I keep the guest WLAN on 24/7 protected by a long ASCII key. I use the guest WLAN for guest devices (obviously) and for internet connectivity for my Wii game console and a DIRECTV wireless cinema connection kit (CCK-W). My guest WLAN is configured for up to 16 device IP addresses.

Provided you use a sufficiently long encryption key/passphrase and WPA2/WPA I see no reason not to simply leave the guest WLAN enabled.

The Linksys E1500 is a cheaper router. Paid somewhere around $99. The guest account is seen via SSID as an unsecured network. However, a password is needed to access the internet. I'm assuming it's similar to an open wifi (like Starbucks) where you'd be provided a password to get on the net.

I'm wondering how secure it is when not in use. Theoretically, could someone connect to the router and do mischief w/o accessing internet with needed password?

Have you tested that? I presume you have changed the routers admin password to something other than the default.

What happens if you use a program like inSSIDer on a wireless computer? Does the guest network showup as not being secured?

I would post to the Linksys forums for help with that question...

I would in anycase use a long password. The Cisco help page indicates you can use a max 32-character alphanumeric password...

FWIW my ZyXEL cost me $20 a few years ago on sale, including an 802.11g USB adapter for a laptop, so cost is certainly not a factor...

IIRC, the Linksys guest access is unsecured. In this case, unsecured means unencrypted (No WEP, WPA/WPA2 on that connection). You can force the user to enter a password, but that just grants them access to the net. Their data is still passing as clear data.

I just saw an E1500 in one of our local Walmarts for $60 FWIW...

Depends on how the vendor implements "guest" wireless. Truth be told, there's no standard for this.
Some just do a 2nd SSID. Others offer full isolation from your main LAN.

For $99, I'd expect something that "just works" and nothing more.

My 00000010bits.

Thanks for the responses. Not much chatter about this subject on the net at all. I will enable it when necessary and disable it for peace of mind. Was hoping that I could simply leave it enabled. But with no standard, the potential for exploit could be there.
