Hello, I'm using windows vista home premium 32bit on my HP dv6226tx with latest updates installed. I'm having strange problem of connectivity frequently. After i browse for some duration or open more tabs, i dont know which reason, i can't open any website other then google,gmail.. Though i can connect and browse any site at same time on my ipodtouch. Both interner explorer as well as google chrome doesnt open any site when such happens but google,gmail works.. After i restart pc, it works again.. sometimes if i wait and dont restart, it starts working and again stops mostly. any diagnosis? wht shd i do? Thanks.
