Re: [Signals] 13dB Jump in Upstream Power Levels after Service R

I think you should be worried. A visit from a tech can get accurate numbers and may be able to diagnose the problem. Upstream of 50 dBmV, which may go >50 dBmV depending on temperature and other factors, may cause lost internet service. My experience is just that, but modems vary in sensitivity to upstream power levels, so your mileage may vary.

To get your upstream signal to noise level you need to call Comcast. That number may be important.

What's your downstream numbers - signal strength, signal to noise ratio? You can have great numbers for these and if upstream numbers are like yours, you may have problems with internet.
