can u remove ur password from router, & check pls?
is ur connection PPPoE?
here it shows PPPoE for me also
chk Airtel & Tata
Keep Alive didn't help
Tried configuring for PPPoE - didn't work.
back to step1 now
after setting PPPoE it didn't got subnet mask, Ip, DNS, etc details.
So it was not able to get online with PPPoE configuration.
