Advertisements About a month ago, Roamio reported V52/53 errors and either 65-70% or a "-" for signal strength on all tuners. SNR is 24-27DB across the board as well. Side note: throughout this ordeal, and starting a few weeks before the tuning issues, I've had sporadic cable modem outages (pings drop, but modem doesn't log any signal problems). Charter came out and said everything was fine, so I called TiVo. TiVo said call Charter. I waited a few days, forced network connections, did multiple hard reboots, and ultimately things magically got better. Fast forward a few weeks. I had Charter come out to look into the sporadic Internet outages. Aside from cleaning up two noisy lines (something behind the wall plate - can't say I believe it had any impact), the tech added a -7db splitter between the line in and my 8-port powered amp (4 ports in use). He said the signal was actually too strong ("15"?) for the modem, so he knocked it down. Immediately after the tech left, the TiVo tuning issue was back. "It's the splitter!" you say. Nope, I removed that and put everything back the way it was and TiVo was still angry. Same signal strength and SNR with or without the recently added splitter on the line in. I suspected the splitter installation or cable maintenance might have caused signal issues at the TiVo, so I had Charter out again. The tech confirmed that signal to TiVo was "40" with an adequate SNR. He also confirmed the signal to my modem was solid as well (+/-2). He said things couldn't be more perfect. So after a loooooong chat with a TiVo supervisor last night (sorry, Jack), they suggested I have Charter out again, but to also have them call TiVo to get their super-secret proprietary specs to measure the signal right (can someone explain this to me?). One last thing to add to all this is that I started having MoCa issues. I'd never had a problem with it, but after the tech left after installing the splitter, the coax light on my MoCa adapter does not stay consistently lit. I plugged a mini directly into the adapter and it did light, so the hardware doesn't seem to be the problem. I checked MoCa diagnostics on my Roamio and I noticed the nodes bouncing from three to four to three every five seconds. After tracking the MAC that kept falling off, I found it was one of my minis. I powered off that mini and seemingly everything is fine MoCa-wise now. Alongside all of this, I emailed TiVo Margret and she provided an update to RC21, which I installed this morning to no avail. To summarize, my problems are: 1. TiVo reports no or low signal, but Charter says the signal is perfect. 2. Internet connection is intermittently down (5-15 minutes every few days). I know this forum isn't for that, but this is still something that could help point to a solution. 3. MoCa has been unreliable - possibly due to a Mini having issues. Help!
