I'd like to setup a guest network using WEP -- I know it's an insecure protocol, but I have an ancient device card that doesn't support newer protocols.

However, when I go into control panel for setting up a Guest Network, Wireless Security options are just "Disable" and "WPA2".
So, is it possible to setup WEP just for Guest network (for testing)?

alternatively, I suppose I could just Disable security on Guest network, and try to restrict bandwidth or days/times (to reduce unauthorized access).

or change my regular 2.4Gz network to use WEP (since it's supported there)
and continue to use WPA2 on my 5Ghz network (since that what most of my other devices use)?
