CM1200 Spectrum Analyzer help

[Tonymontanaalb]

Hey everyone. Ive put in 192.168.100.1:8080 for the spectrum analyzer on the CM1200 modem and i get the following graph looking thing. looks like signal issues coming into the mdoem from the provider maybe?

Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Be sure to power OFF the modem for 1 minute then back ON.

1. why do you think you're having signal issues? 

2. got a screensnip of the cable connections page and the event logs?

[plemans]

did you check your line/connections? 

You don't have "errors" in your line per the screen snip (event logs tell us more......) but your power should be within 3.5dbmv of each other and you're running from -1 to 5.5dbmv. so a 6.5dbmv difference.

Also only 1 channel locked in? 

Whats you uplink speed that you pay for? 

[plemans]

Plus your upstream is quite high. making me think either you have something in the line. Whether that be an amplifier causing you to have higher downstream and upstream. (needs a higher upstream to boost the signal to the cmts from the amplifier).

im paying for 1Gb

[plemans]

what else is connected to the coax line? 

Did you remove splitters, amplifiers, and signal attenuators? 

Like I said, your power levels don't make sense between what your upstream is versus your downstream

You have a 1Gb on the UP? IF so, you should have more then 1 channel locked in for the up channels...

I haven't seen a single ISP have reciprocal speeds on cable connections. Not sure what upload speeds spectrum has on their 1 gig plans.

I guess. I know for my 1Gb x 50Mb I get 4 locked UP channels.
