I've been having static on my uverse Phone for the last week or so. I've tested a different phone plugged in and even directly to the modem with a new phone line. Does my signals below show a possible signal issue?
I haven't really noticed a issue with the TV & Internet but phone has gotten hard to hear people sometimes.
More than likely an aging analog telephone adapter in the modem. Engage tech support and make sure you let them know it's still staticy even with different phones plugged directly into the modem.
