Comcast upstream power too high
Upstream power levels that are too high will affect a modem connection's consistency. As the levels increase, the modem's ability to connect to the provider decreases, which may cause the modem to power down or disconnect.The modem status will show the downstream SNr (signal to noise ratio) which usually should be above 30, mid to upper 30's is good, over 30 usually means you've got too much power anyhow, and under the 2530 range you're gonna start losing packets. comcast upstream power too high
The downstream power level being between 13 to 15 is high. This is something you will want to get in touch with the internet provider on to have this adjusted closer to zero as possible. This would indicate possible cable plant issue. Once the signals are adjusted, you shouldn't be having the connection issue.
Apr 15, 2014 In general if the upstream value is your problem, Comcast shouldn't charge you as it relates to something within your network. Your upstream power level is too high. It's supposed to be within 50, and with you being right on the border I bet that's causing an issue. Ask for a tech to come out and they should see that. I had an issue where there was a kink in the line and if too many people were on the downstreamupstream would to go hell. Had to have them fix it to resolve it. Also, if you're using 2 splitters that'll cause an issue.comcast upstream power too high Aug 02, 2013 I thought I would share my fix for constant dropped connections on my cable modem. Faced this problem for about a year and finally got it fixed! This is only a fix for high upstream power
