High Upstream Channel Power and T3/T4 time outs
Hi maybe someone can help me, over the past year I'm having increasing T3/T4 time outs with loss of connection 5-10 times a day. I spent hours on chat with Xfinity and they told me to connect the modem directly to the drop coaxial cable - which works and decreases the errors, and also reduces the modem upstream power from 51-59 with splitter to around 47 without. They spent most of the time trying to up sell me on renting their gear and adding more TV I don't need. The 3 way splitter connected my modem and 2 TV's, now to watch TV I have to go outside and attach the splitter, which I think is a ridiculous solution. I also tried only connecting one TV to the splitter and it was better but still too frequent T3 errors, and upstream power above 50. The photos are from after disconnecting splitter so you can see the upstream power decreased to 47, the error logs show the time outs prior to disconnecting the splitter. Thanks for any help, I'm strongly considering switching to RCN. Also the modem is Netgear cm1000 (recommended by comcast) and I also have a Netgear Nighthawk router.
