I use bsnl broadband connection via an ADSL wired modem of BSNL.It works perfectly.However when i connect the ADSL connector in the WAN port of a newTPLINK wifi router which i have recently bought it is not detecting the ADSLconnection wire and the WAN port is not blinking.However the port is detecting connection provided by alliance broadband which i checked from my neighbour....I even tried changing the IP from 192.168.0.1 to 192.168.2.1 but its not working.. Its reporting a problem regarding IP conflict after the change.....What can be done?? please help.
