Tenda router not working with Idea broadband

[swapnilpingle]

I have been using tenda router for local ISP and it worked perfectly fine. Recently I switched to Idea broadband and my router is not able to connect to internet.
PS: Broadband connection has internet connectivity and it works perfectly fine when directly connected to laptop

Perhaps you need to release/renew the wan IP address as it may still be trying to use the previous isp's. You do this is the routers control panel applet.
