TV PIXELATION since bandwidth upgrade
Looking for any assistance here with my Uverse tv service. July 6 weeks we upgraded our bandwidth from the 18Mb tier to the 45Mb level. Since the upgrade we have had the following issues. When we record a single program and try and watch another channel the tv signal the picutre and audio pixelate and become unwatchable. As soon as we stop the recording the pixelation clears up and everything works fine. As part of the bandwidth increase we have a new gateway and now because of the pixelation issue we had a new box sent. The new box was installed on Jul 13 and once AT&T updated the software and reset the gateway everything worked fine until July 19. Last night the problem started again. We have reset the receiver as well as gateway and are still having the issue. As long as we only record one thing and watch said program it's fine. The internet has had zero issues since the upgrade only the tv signal. We had no issues like this before the bandwidth upgrade and are quickly losing faith in AT&T.
Anyone else have an issue similar to this?
