How to configure DSL-2750U router with Reliance wireline broadband

Hi,
How to configure DSL-2750U router with Reliance wire line broadband?

some time it connects but just within few minutes it stops working.

If the broadband connection is working then I don't think there is anything to configure, it is some problem with your connection, which needs to be resolved by the service provider.

Please post your modem stats page screen shot. Your line seems to be the culprit. If you dont know what that means then give customer care a call and tell them that your connection drops every now and then and they will check your line quality and if they find the quality to be bad then will send some one over to chekc the joints at the junctions box and at your house aswell.

In the mean time you could try checking the joints in the cable inside your premises and make sure they are joined well and clean the terminals of your telephone cable that goes into your modem. Apart from that there is only so much you can do really.

Please go through this thread by Just4Kix : SNR Margin and Line Attenuation - What do they mean? This should give you an idea about what your line is capable of and what it is not.
