I have been reading too much community forums trying to get LELA to work. I just changed my security from WPA to WPA2. Downloaded the patch on the XP machines. All is fine on the XP side. Now my Vista machines cannot connect. "Windows cannot connet to XXXX The wireless network security key is not correct. OK I'm not totally dumb but I entered the key, a combination of 11 characters. I can see the passphrase when I look at the router from my XP machine and can see the passphrase on the Vista machine when I click Display characters so I know they are the same. This is true for connecting to both the router and access point.
Using a WRT300N as the router and a WRT150N as the access point.
