I recently switched to AT&T U-verse and a few rooms in my house gets poor signal. The AT&T router is downstairs and a few rooms upstairs has issues. I want to connect a power line network and was wondering what would work? The AT&T router has 4 Ethernet ports. I would like to plug in a power network into one of the Ethernet and connect to my power grid then plug in a range extender that works on the power grid. The router does not look to have any ability to manage and range extenders so this might have to be something that works off my router (stand-a-lone ??).
The AT&T U-verse router is made by Pace Pic, Model 5268AC.
