Router Doesn’t Work After Replace New Modem – AT&T Tech Support Sucks

THE CAUSE: private IP address conflict, the new modem’s and the router’s first 3 octets are the same i.e 192.168.1.X

THE SOLUTION: change your router’s third octet of its IP address to something between 2-254 such as 192.168.2.1

So I have offered the fix right up front for those who don’t give a rat’s ass about my miserable story. If you have some free times and don’t have anything better to do then feel free to continue reading my frustrated experience.
