New phone line connection cable
The home wi-fi router began to fail intermittently on Friday. That night, I called AT&T tech support and was told, after going through several diagnostic procedures with them, that the router needed to be replaced.
I was sent a new router on Monday. Upon installation, the "Broadband" green light only flickered and never came up fully green despite my going through several diagnostic steps suggested in the accompanying literature and on the Smart Home Manager app.
Since the new router seems to also be failing, should I try a new connection cable from the wall jack to the router?
