Re: Signal Level Check for Xfinity Connected CM1200
Hi can someone advise on whether the downstream signals look acceptable? Ive had occasional drops (few times per month) tied to SYNC Timing Synchronization Failure errors. I read that +/- 7 is the ra...
Thank you. I note that the levels I showed you are with a 6 FPA attachment. I just added a -10 FPA on top and the numbers now look like this as a result. It’s definitely a signal with too much power downstream. Thanks for confirming my suspicions. I also have the cable company (OPTIMUM) coming over tmw to replace the exposed coax outside my house (extreme cold cracked the coax and can see the metal sheath) and the splitter connections that they are responsible for is corroded. They DONT maintain anything unless they have to 🙂 Go figure.
Now the power level is a bit to high for upstream. A cracked line would cause major issues. I'd hold off on more changes until they fix the line because you'll probably have to redo some things once you have a solid signal coming in to the home.
