I have a windows vista PC and an XP laptop . I m using adsl connection for internet . I have directly connected my vista PC through LAN cable to the wireless router for internet access and laptop is connected through wireless on the same router. now, whenever i shutdown my wireless on the laptop i am able to surf net on my PC but when both are switched on I am unable to surf net on any of them but the twist is i am able to chat in yahoo messenger and gmail on my laptop but not on my PC when both are switched on. while troubleshooting i found that PC and laptop both can ping any website address simultaneously. CONDITIONS : 1. BOTH ARE SWITCHED ON : ON LAPTOP ---- can chat thru messenger , can't surf the net, responds to ping . ON PC -------- can not chat, can not surf, responds to ping 2. WHEN LAPTOP IS SWITCHD OFF ON PC --- connects to internet properly. no problem. how can get proper connectivity on both ?
