Ok so here is the story. I had a MTNL T-KD-318-EUI router with me so when i took Airtel BB[read Airtel BB] about 4 years ago i dint opted for a modem from them.Now The best thing about this modem was that somehow i was not affected by their FUP [may they wasn't able to track through this modem], But from the time i am using my friends D-Link modem i am capped every month, FUP limit hardly last 1 week now. But one day while trying to port forward i accidentally hit the factory restore button, and BOOM!! the internet was gone. I tried to configure it by myself but was not able to connect to internet searched a lot of forums but all in vain so i called up CC they weren't able to make it work, so they sent their "Engineer" to my place, he wasted a lot of time but finally gave up saying that This modem is not supporting from Back-end. I asked that if it was supporting till now how could it not anymore, he dint knew what to say.The best he was able to do was to make internet accessible by Bridge connection on this modem but i also have to connect my Net-gear WiFi router to this modem which it does not support on bridge connection because apparently you can only connect 1 system using bridge mode.Does any body here knows how to make it work/Bypass it again?I sincerely does not know what to do because i want to switch my BB as soon as there is a reliable BB/ISP here in Delhi, so taking modem from them will be like wasting my money.If i buy modem from Market am not sure it will support Airtel BB for how long if no good ISP shows up just like it stopped supporting with this MTNL TKD modem.
