I have experienced this problem a number of times in the past few weeks. I get logged on and am assigned an internet IP address. However, I am unable to browse and various softwares complain about the absence of an internet connection. Is this a problem with their gateway?Usually, the problem gets solved in a few hours or overnight, but lately the problem seems to occur more frequently and is prolonged.In fact, I am unable to browse since exaxctly 10.00 AM on Sunday. It is now 9.30 PM Monday, but the problem persists. I am posting through my backup MTNL connection.Has anyone experienced such problems?
