Netgear CM100 random resets

Anyone have a CM1000 that randomly resets? This happens like 2-3x a day sometime.  Log shows errors like this:

Re: Netgear CM100 random resets

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

Re: Netgear CM100 random resets

Thanks for the quick response!

 

There were a lot of different power levels under downstream and upstream...

 

So I think what you're looking for is:

Downstream:  -2.9 dBmV

Upstream:43.8 dBmV

SNR: 38.9 dB

 

If not, see below.  

Thanks!
