I moved my AT&T router to another room. I ran a longer cat 5 cable from the wall where the service enters the house. To a wall connection in my living room. From there I powered up the router and plugged to original cat 5 from the wall location to the ONT Broadband port. Now I have a green light for power and wifi, but to blinking red lights for broadband 1 and 2. Am I not able to add a longer cat 5 from the service connection at the wall?
