Ever since we swapped out a bad Belkin router for it's replacement, I can't get 1 of the 4 wireless computers that run off it to work right. The other 3 run great. I get an internet connection, but then a few minutes later it drops. First the network says "limited connectivity", then "local only", then it's back to "local and internet". It's an HP G70-460US laptop, windows vista svc pk 2, Atheros AR5009 adapter. Belkin had me remove & re-add network, change router channels twice. I ran diagnose network adapter, reset adapter, check adapter drivers are up to date, uninstalled last windows update, disabled norton firewall & antivirus. Nothing is working. H E L P !!!!
