Modem Problems?

Question

My modem connected to ADSL line keeps on restarting itself what might be the problem and what can i do.

Answer 1

Sounds like a basic hardware failure, such as the power supply electronics or a number of other things could be failing. If the modem itself is stuck in an endless reboot cycle, and powering if off for a little while and back on does not fix this, you'll have to contact your service provider for a hardware replacement, or if you own it, hopefully you have the receipt so it can be returned for a replacement.
