AT&T related help: U-verse TV support
U-verse signal has been lost. Only on active channel for a few seconds.
Modem: BGW320-505, installed two months ago. Set-top boxes: Cisco ISB7005, connected by ethernet cable. Since our modem was replaced two months ago, our U-verse TV channels freeze every few minutes on both our TV sets. Some Details: After frozen for a minute or so, an error message appears on the screen: “U-verse signal has been lost”. If we wait several minutes, the TV feed resumes. If during a freeze I switch channels, other channels work immediately. If I switch channels and back to the first it is working, even if I switch back within a couple of seconds. The freezing seems more frequent on some channels and times of day. Recently, in the evening, channel 1030 is unwatchable; it freezes for a few seconds several times a minute.
