This is an offshoot of an earlier thread of mine ( C125 error for 3 weeks -- no end in sight -- cannot connect to Tivo service ) -- for some unknown reason, my Google Wifi will not allow me to connect to the Tivo service (Tivo Premiere XL). Tivo thinks ports 37/123 are closed -- they are not, as I have confirmed with Google Wifi, after using the app to open those ports. After a series (think a month) of multiple (too many to count, or at least to want to count) tries to fix my issues, I had tried going from wireless to ethernet, multiple sequential connections, etc, etc, etc...40 hours in all, I'm sure, including having Spectrum come out and test my modem and router... I replaced the Google Wifi with an old ASUS 68U. It connected immediately. Does anyone have any idea of what in the world might be going on? I am going to try switching one of the "children" points in for the main hub to see if that changes things, but I am at a loss in figuring this out.
