Tuning Adapter Reboot Issue New Tuning Adapter UPDATE
It's just about a month since Cox updated my Tuning Adapters with the new dual frequency adapters. In the last 30 or so days, it has rebooted twice, for a very short period of time and did not trigger the "tuning adapter not connected" on the TiVo. Other than that, it has worked flawlessly. I would imagine TiVo will be releasing the new adapters sometime in 2023 subject to availability. They have not been in touch with me to see if I have had any issues but did give me the email address of the person in charge of the issue to report any problems which I have yet to have to do.
For those who asked I am in the Phoenix Metro area and the Chandler facility.
