Now again some strange problem with MTNL.
Too many frequent DC with MTNL delhi , (I am using freedom 800 plan) but i dont think it has anything to do with plan. Looks like just MTNL issue, Link in the modem is stable but internet is disconnecting at fixed intervals frequently. It started 2-3 days back.
before this Ping issues on gaming server was my problem which I am facing till today.
