It is a big headache. We all know about BSNL's Night unlimited. It was never been easy to deal with it. Earlier we need to reboot our modem at 2.00 am and 8.00 am. Now after server upgrade, new errors are popping up. We can use Imran's Broadband Helper utility or batch files to reboot. Imran's even reconnect.

Procedure:

Control panel > Network connections > Choose you dialler > properties > Options tab > check the box " Redial if line is dropped "
