We just reset our home Linksys router because we forgot the password. We set it up fine using WPA2. It worked immediately on all computers.
We have one Vista laptop. When we first set up the reset Linksys router, this Vista laptop did work. It connected to the WAP and got Internet.
Now, though, it doesn't. It can still connect to the WAP, but connection says local only. I run IPCONFIG and it has all the settings (default gateway, ip address, dns servers), however I can't even ping the default gateway (so the linksys router).
