So I have a Tivo Bolt Vox, a Tivo Premier, and a Xfinity X1 box. The X1 box stopped working, so I went to Comcast and exchanged it after troubleshooting over the phone. The new box didn't work either. Comcast came out and determined that my signal strength was too low. They installed a signal booster and well as a POE filter. All devices were working, but before the technician left, my Tivo Bolt stopped working. They technician spent the next two hours trying to fix it, but had no luck. I have had multiple conversations with both Tivo and Comcast trying to figure out the solution. Whenever I talk to Tivo, they always ask me what the value is for "AUTH". Auth does not even show up on the cablecard screen. I have verified that the cablecard is authorized. All of my devices work on the outlet that the Bolt is connected to, including the Tivo Roamio. The Bolt will not work on any other outlets in the house either. I have tried 3 cable cards, tried pairing the cable card after bypassing the signal booster, nothing seems to work. I've looked online and it seems like there are others with similar problems, just not sure what the solution is. I'm supposed to have another Comcast technician come out today, but not sure what they can do since I'm told that I have the correct signal strength. Also spoke with Tivo yesterday. They are sending out a replacement Tivo to try that. I wasn't real happy that they are charging me $49, but at this point I'm willing to try. Been a Tivo customer for almost 20 years and have never had a problem. I really doubt that the replacement will fix the problem, but going to try it. Anyone else have this problem? any ideas? I like challenges, but this is starting to really tick me off!!!
