Hi,Thanks for the reply.Port forwarding issue is resolved, however, frequent hanging of connection still persist.I dont know what is wrong with the connection. I had a talk with BSNL people also but they were unable to help me.When the connection works fine, it works fine for 10-15 minutes but then after 15 minutes or so the connection hangs again and some sites open and some does not. Downloads and torrents are working fine.I tried other dns servers as well but in vain.Tried gdmt also. But i do not see any change. What should i do now?Please help.
