$20 to anyone who fixes my vista wireless internet problem?

[tox0tes2]

****I WILL SEND A CHECK FOR $20 TO ANYONE WHO GIVES ME ADVICE THAT FIXES THIS PROBLEM****

I have a newly built computer that I assembled last night and the wireless is not working. When I try to connect, it says "connecting to the network is taking longer than usual" and then after awhile it says "connection unsuccessful"... then I hover over the network icon in the taskbar and it says "unidentified network: local access only"

I cannot open web pages. I have filtered through many pages of google results on this problem and nothing i saw fixed it.

More details:
windows vista ultimate 64bit sp1
brand new linksys wireless-g pci adapter with latest drivers
linksys wireless-g DSL router
wireless network does not have any kind of encryption

(no WEP, etc.)
DHCP enabled

two other computers in the house work just fine with the wireless.... one with xp home 32bit, and the other with vista home premium 32bit

Do you have MAC Filtering enabled? I have seen it many a time with XP where people will attempt to connect and get a similar response when their MAC is blocked on the router. If this is the case, add the MAC to the list of MACs able to access the router.
