Hi Kapil

1. How many devices do you connect to TD-W8968 via wire or wireless?
2. For those who can't connect to TD-W8968's wireless, set a static IP on your device, then check whether it will work.
3."Modem keeps on disconnecting (auto disconnect is off) now and then (3-4 every 5 mins)"
You mean Internet drop?(Both wire and wireless?) What's the state of ADSL light and Internet light? And can you log in TD-W8968's web page then?

Have you tried to reset your router and reconfigure it?

1. 4 through wire and 10 through wifi.
2. I have checked with both static and dynamic IP, nothing solves my problem.
3. Yes my internet drops both wired and wireless, ADSL status link light goes off and internet light goes off as well. And then after about 5 minutes both lights come back and internet starts working. I can access my router page even when the Internet drops in between.

I have resetted the router many times and have thereafter reconfigured it, but no luck. But we didn't face any issues when we used Belkin N150 for a couple of days (for testing).

No one response till that is the service you provided to people.

what is the sla of your company.

Have you tried change some settings? For example: in Network-->DSL settings, change DSL Modulation Type to G.dmt.

Maybe it work, if not, maybe you should contact the shop where you buy it as it's broken :)
