Xfinity Internet is Constantly going down and staying down

Latest update. Looks like the power went down?

Actually, it went up. It's now closer to 0 dB which is better. -7 dB to +7 dB is the desired range. Did you do something to improve the connection quality ? If not, it shouldn't be making such wide intermittent fluctuations itself. It the connection more stable now ? What do the *Upstream Power Level* numbers look like ? Please post them all.

And the upstream power is on the high side to being out of spec and it may be intermittently fluctuating even farther out of spec. There's no wiggle room. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.

In an effort to try to obtain better connectivity / more wiggle room, check to see if there are any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage from Home Depot, Target, Wal-Mart, etc. Splitters should be swapped with known to be good / new ones to test.

Also check the coax cable for any damage such as cuts, nicks, abrasions, kinks, sharp bends, etc.

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two-way splitter connected directly off of the drop from the street / pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.

Good luck with it !

Comcast updated our Internet in our area. Supposedly, about a couple of months ago, and now it goes out all the time. I get weekly text from them saying their Internet is down and they’re trying to fix it. This is affecting my work and my school. Now that everything’s on Internet it’s pretty difficult to do work or school when you have no Internet

This is the annoying text I get every week, when the internet goes out. Since the supposed update to Comcast in our area, good luck with working from home or doing on-line school. It’s out weekly for hours. Before the supposed update, it never went out, maybe once a year. If this keeps up, I’ll have to research the other companies. Can’t have my internet continually going out. Work and school has had enough of the excuses. See the below text. I just got it again tonight.

This has been what is happening to me as well. Internet on and off - no one seems to be addressing it in a timely fashion.
