DSL connection issues

[aramtilak]

I am able to work on a single laptop with my ISP provided DSL router.

This was connected to a DLINK WiFi router - this started having WiFi connection issues - switches on and off.

I bought a D1500 DSL router.

DSL light glows OK

Setup is OK - kept everything default. 

But am unable to connect to internet 

The old DSL modem is unable to connect to any other WiFi modem now.

But internet works over ethernet cable from the ISP provided DSL modem - so I cannot ask for more support from ISP

Any ideas on what else to try

You probably need to supply the login details for your ISP, the username and password for example.

Look for the Internet Settings bit in the manual

You don't say which ISP it is, that could help someone who uses the same service to guide you. It may also be on the ISP's website.
