Here is an alternative(just thinkin' out loud)....
I am guessing you don't want to invest at this time in the additional expense of Cisco devices; right or wrong?
Per my diagram below:
- You will need, a box that you can install IAS and possibly a CA(Certificate Authority) on.
- If you dont have one and just wannt experiment, download vmware server(for free) and you can beat it p all you want.
- If you do not have a managed network switch, you will at least need multiple NICs in your server. Two NICs, one for the Guest LAN and one for your Corp LAN
- Try this out
- The IAS box will house your usernames and passwords for access.
The bottom line here, is that the Linksys AP will HAVE to connect to an external db for authentication.
