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.

Can't see your pics. Since you are a new poster, they need to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting them at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to them here.
Or copy all of the text of the status page and paste it into the body of your next post here.

Thanks, after removing the splitter I think there was only the two warnings at the top of the event log "Dynamic Range Window Violation" Most of the other one's with splitter in place were T3 and T4 warnings.
