[himadri_sm]

i have three desktop PC's & 1 netbook.....the desktop PC's are connected via a wired connection & the netbook is connected via wireless.i have a belkin g wireless router ( model no- F5D7234-4-H V5).the netbook is a dell inspiron 1210 running windows Xp Sp3 & the PC's are all running windows 7 ultimate.the problem is when i connect to the internet wirelessly on my netbook...the internet connection drops in all the PC's & also the netbook.no site will open..& it shows "URL is not valid & cannot be loaded"...but when i disable the wireless connection on the netbook, the internet connection remains fine in the PC's & i can browse everything.the connection also drops if i connect the netbook using a wired connection.that is, the internet just disconnects the moment i try to connect with the netbook. sometimes, the connection comes back for a few minutes & then goes away again......sometimes only google will open.its like the connection comes & goes but for the most part, it is mostly gone. what should i do to solve this problem?

buddy try a fresh install of Win Xp SP2. SP3 is famous for some notorious problems (me, friends & relative experienced).
