I have an MTNL 256kbps unlimited account, and have been provided with a UTStar ADSL router. My connection dies automatically after a while, with the duration ranging from a few minutes to a few hours (usully averaging 1 1/2 hours, but fluctuating greatly). While the network continues to be shown as being connected, there is no data transfer. Restarting the computer is the only way to counter this problem, after which it works just fine for a few minutes (or hours) and dies again. I use win xp sp2. Please advice.
