Reseting modem and router several times per day.

Download ChannelsFor several months I have been having to reset my SB6190 (24 x 4 bonded) and Netgear VSF318G WiFi router after I lose connection. My router only operates at 2.4 Hz. When it happens, I can't even log on to the router or modem. I'm thinking there are 2 problems here. First, my router is getting shut off by WiFi noise of some type and second there is a problem with my service.

I read the signal explanation file posted and it seems my Upstream signal level is a bit high floating around 50+ dBmV and 15+ dBmV Downstream. There are a lot of uncorrectables.

I have internet only service and use TV streaming boxes, T-Mobile WiFi connected phones, Kindle books, DirectV ethernet. Using 300 service.

I tried posting picture of modem pages but didn't seem to work or I did not do it correctly.

Try a direct copy and paste of the signal levels and log page instead of a picture. This has worked for me in the past.

Unfortunately, I saved them as jpg files so I can't copy text from them. Need the correct format for "source" on the insert from image icon. Already dropped signal and had to reset since I posted.

I need the specific format to enter the "SourceEvent Log" of the jpg in order to make it work, since I tried C:\folder1\foolder2\file.jpg and it did not work. Would be nice if field label had example.

Incidents are random and seem to not be related to anything I was doing. In one case, modem dropped to half speed (3rd light dropped from blue to green when router was not powered on and nothing else was either.

Router has latest firmware installed from Netgear. Modem firmware is supposed to be latest as reported by TWC, which has total control of firmware installation as reported by modem manufacturer (Arris brand SB6190).

Re: Reseting modem and router several times per day.

Also, the line underground from street to back of my house was replaced a few months before this started happening after a contractor accidentally cut it. I don't use TV service, so internet is only connection. Problem seemed to start after subdivision across main road from my subdivision experienced a major power outage.

Re: Reseting modem and router several times per day.

Tech showed up and measured signal at -3 at the street/tap and is placeing maintanance call. Showed me his ability to see signal drops over past 2 weeks, which begs question why did the person I called did not see same information. Now waiting for repair.

Re: Reseting modem and router several times per day.

ALL OF YOUR LEVELS ARE WAY OUT OF SPEC AND IT"S WHY THIS WON'T WORK!

DS too low, S/N bad, too many correcteds/uncorrecteds and probable ingress as well.

 US Levels are at max and 2 channels are missing, trying to rout available power to the 2 remaining channels.   modem s/b in the -8 to +10 DS range and US must be below 51 dB on all 4 channels with + 49 or lower being optimal.

 

 There is either an open splitter in line, a corroded connection, or the line is bad, You should not have 12 dB of loss unless there's 300' of line between the street and the modem.

Verify the line runs straight from the outside grounding block to the modem and there's no wall plates with splitters behind them or somewhere hidden. Connect the modem directly to the outside grounding block to measure levels there.

Re: Reseting modem and router several times per day.

Tech showed up at 6 pm. Measured 9db at the box on my house and 3 db at the street. I have a long run of about 200 feet. He replaced the connector on the house end of the cable. Said it was Spectrum problem and that someone would come fix it. This morning, after an appointment I checked and my 4 uplinks are back and running at the following:

Corrected/uncorrecteds much lower. Seems to be working faster than before. No time-out errors in log. Log is empty after tech left. Only thing I did not like was the phone support person(s) I spoke with (except most recent) should have seen the signal drops and called someone out months ago.
