Re: Netgear CM1000 Modem Issues "Intermittent connectivity"

I got updated from the Firmware Version V3.01.04 to the Firmware Version V3.01.06 and now my CM1000 at least once a day gets a amber Internet connect light so it is only running at 100MB instead of the 1GB is always got before this update. To get my green light back and 1GB I either have to reboot or power off or disconnect the wan patch cable and then connect it again. Any one else having issues with this new Firmware Version V3.01.06?

not at all, i've been stable since the update. Have you looked at the modem event log?

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.

As soon as I said no problems, connection got sluggish, even my IOT devices started not responding, checked the logs, and this starts:

Re: Netgear CM1000 Modem Issues "Intermittent connectivity"

I figured out and fixed the orange Internet light issue and speed. The firmware messed up the commuications with the Router. I did a factory reset on both the Modem and the Router and that was fixed. We are still having issues with the TVs Pixelating on a daily basis plus now and then T3 tiemouts. The codewords are off the charts on a daily basis too. If you look just at the signals they are all within spec, so I feel it has to be a noise issue. The upstream was going instantly at times from 46 to 54dbmv but the maintenance tech fixed that. They just haven't been able to fix the noise issue. This round of issues is going on 3 weeks now and when it comes to my bill I'm going to expect full compensation.Uncorrectable codewords 5 minutes after reboot after maintenance 9-10-2018.JPG
