Pixelation issues on wired Uverse cable boxes. How to solve it with use of the Ethernet IN port
I have a problem with pixelation on an ATT wired Uverse cable box that is 3 floors away from my router. I have had this diagnosed by ATT Technicians multiple times. They reset my network and get everything in sync but over time the pixelation returns. I have grown tired of the constant resetting and visits. They have replaced my router twice and checked the wiring multiple times. I discovered a "fix" by accident when I used a TP link power line extender to extend my wired internet to provide stability for my PC so I could use it for work from home activities. It turns out that the power line extender technology also extends the Uverse signal through your power lines ! I was shocked to find out it really does ! When I connect an externet cord from my power line extender to the Ethernet IN port on the back of my wired Uverse cable box, disconnect the coax that traditionally carries the Uverse signal and reset the wired cable receiver box.... perfect picture... no pixelation... no coax feed of Uverse required?
My question. Is ATT aware of this? Apparently ruining coax over long distances, where it may pick up interference, causes Uverse to stay in an out of sync mode. Using power line extenders to extend your internet seems to resolve this !
