Check the wifi setup in the router. If the encryption is TKIP or TKIP+AES, turn off encryption temporarily (IOW an open router, no password), "forget" the connection in the phone and connect again.

If that solves the problem, and you don't want to run an open router, change the encryption to AES and see if the phone works that way. (Forget the connection, then connect, so it's not trying to connect to an unencrypted connection, which is what it "remembers" from before.)

Depending on the router, that may still not fix the problem - Linksys still runs VERY slowly with Android, even with AES (VERY slow meaning about half an hour to download a small jpg file). My solution was a $40 Netgear WNR2000. Normally I wouldn't buy Netgear - I consider it "2nd level" in home equipment, but it's cheap and I get almost the same speed on my phone as I do on my desktop (and I think the difference is due to the ROM in my phone being a bit slow doing wifi).
