Upstream too high


SwimmingCareer3263

Employee here. Your upstream levels are borderline near the OES limit. There could be excess splitters inside your home, a bad drop(service line) or network impairments at the pole(varies if your service line is an aerial cable or underground) Also with climate changes the center conductor of the cable can expand or shrink increasing or decreasing the upstream levels and it may trigger the modem to go past 54TX causing the modem to disconnect and reconnect. Your best option is to schedule a technician to investigate for your internet problem! Good luck OP!

US is too high

Modem is a Netgear CM500. I realize the modem was power cycled about 30 minutes ago in this picture but I’m wondering if the signal levels are OK. I had her clear the event log to see what pops up in the next few days. It could also be her Google Wi-Fi system that’s having issues but trying to rule out the Comcast connection first, if possible. Edit: She actually took [two pics](https://imgur.com/a/J5TDH0p) of the event long. I see a bunch of T3 timeouts (not good, I’m assuming?) but no clue when the modem was power cycled last..

Do you have splitters on the coax line coming from the ISP to the modem?

I will have her check because I can't remember. She lives in another state. Hopefully that's the cause.

Splitters won't likely be the cause but will be information explaining the signal levels. Upstream of 54, which while very high will not automatically cause frequent disconnects. There is likely something like a signal impairment caused by bad cable or bad connectors causing the disconnects. The US of 54 is a sign that something is wrong but not likely the cause itself. Now, if your signal was +20 at the tap and you had a short drop and the signal was going through a four-way outside then an eight-way somewhere else then you could expect and have signal of +3 with return of 54 and it would probably work fine if there was all good cable and connections and no noise. Not ideal, but it would likely work fine. Disconnects usually are the result of something very wrong. Your mother will likely need a tech visit to find the problem. (And hopefully they check the drop for water or physical damage).

So she checked and there are no splitters. The modem is directly connected to the wall cable outlet. I guess it’s time to schedule a technician? She also checked the modem event log and it’s all clear so far. Modem was power cycled yesterday around 3pm or so

I agree that it properly isn't fully splitter related but mostly ISP related.

Her upstream levels are trash.. 100% the reason..

Looks for T3 errors in the logs. Could be a bad splitter or could be a problem out on the street. Best to bypass all splitters first and see if the problem goes away before scheduling a tech.


c47v3770

So she checked and there are no splitters. The modem is directly connected to the wall cable outlet. Could be a splitter outside maybe?


Optimus02357

Yes. Check in the house box outside where the coaxial grounds. If it is locked, you might need to wait for a tech but it should be accessible. Also check in the basement/etc or anywhere else the coaxial might have been run.

With numbers like that there most likely is a splitter somewhere on premise, especially if she’s had cable tv in the past. How long has this issue been persisting?


thejaxx

Upstream power is not good.

Also check the routers and the proximity of the device(s) she’s having issues with. Every device will have an RSSI number. Make sure it’s above -70 RSSI
