Intermittent Connection

What do the modem's signal stats look like ? Try getting them here; http://192.168.100.1

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

Is this with a WiFi connection ?

Downstream Channels 33 channels, All locked, Power Levels -2.0 to -4.2, SNR 40-42 dB

Upstream channels 6 channels, All locked, Power Levels 45-46

Incidentally my modem can only be reached with 192.168.0.1

Waiting on your reply. Told you my network is wired , WiFi is an option with my modem but it also is intermittent.

The signal stats sound o/k. Are there any modem component error log entries being shown ? If so, please post them as well. A screenshot of them or a copy and paste of all of the text will do.

No , I have not received any modem error messages in any logs. I have checked all my wiring with a cable tester, checked all configurations of my computers. I am beginning to suspect the the problem might be Comcast cables inti my home. I just bought a new modem MG8702 approved by Comcast and installed. The problems still persist of intermittent access to the internet. I am having problems just taking care of any internet  interactions to the point of insanity and frutration.

The signal stats are o/k but perhaps there is noise ingress into the line(s) somewhere.

There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.

I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They will be able to poll the CMTS to see whether or not everything is in the green zone, see your node / cable plant and modem health, and also see a history plot for the modem. You should get a reply here in your topic. Good luck !

This is my at least 10th attempt get Comcast to fix my problem of intermittent connection. My internet drops at least 100 times per day and has been doing this for several months now. I contacted Comcast by phone and talked to Tiffany 5 days ago. She said they would trubleshhot all my outside connections first and then get back within 72 hours. It has now been 5 days and no respose from anybody. This must be fixed or ww will have to find another provider. This has been going on so long now, it is hard to believe that Comcast is doing absoultely nothing about it and has not gooten bvack with me as promised. I think they owe me a big, sifnificant refund of money.

I'm going to try re-escalating this.

I finally got Comcast to come out. The subcontractor seems to think my signal is good but I still have intermittent or no connection on my 3 computers and laptop. I have tried wired and wireless, get the same bad result. No one from higher up in Comcast has made any attempt to contact me. This is totally unacceptable and must be fixed or I need to find another slower provider before I lose my mind.
