Wireless Set Top Box; Red X 3
I'm having a problem with a single STB. I have 6 STB, some wired and some wireless. I have AT&T fiber. One of the wireless STB went out. The error at that time was "Set Top Box Does Not Match Account Settings". Multiple reboots of gateway and STB, did not fixit. All other STB and wifi were fine.
AT&T sent a new box (VIP2500). Plugged in, pressed WPS...connection successful. STB updated and now i get red X 3 error. Forced reboot (ok + down). I get one cog, progress goes fine, then two cogs. progress starts and ~20% of the way it stops and i get a red X3. This occurs with different TVs and different locations in the house. It occurs wireless as well as wired to the back of the Gateway.
What can I do to fix this? i have rebooted gateway a few times, tried different TVs, wireless and wired. I can't imagine that AT&T sent a defective STB. Is it something with my network? Is it something with my account?
Thanks and Happy Holidays!
