Thread: Dlink DSL-2640U wireless router

I have bought this router...and i dont know what i am doing wrong i cannot connect to the internet. when check the log. It say authentication failure.. Please help...

what is the login id u r using? try appending @a to your telephone number. Your password is your CA number.

ya have put that all correct...i get no error from MTNL's router..bt wen i try from the dlink m getting this "pppd[586]: User name and password authentication failed."
