Re: cm1200
The screen shots of the cable connections page and logs help with checking line issues.
Also, if you have any splitters, amplifiers, attenuators in line, remove them.
check the line for kinks, damage, corrosion, cheap/bad/loose connectors.

Re: cm1200
I am having the same problem. ISP came out and checked the signal, reterminated the coax, and removed a splitter. It seemed OK for a couple of days before service dropped again. If I unplug the modem and plug it back in service is fine for a while. When the connection is down the upload light is flashing. Just got off the phone with Netgear and am trying a factory reset....

Re: cm1200
What firmware version is loaded on the modem?
Who is your ISP?

Re: cm1200
What speed UP and DOWN do you pay for?
I'm seeing only 16 channels locked in which means that you not paying for a high speed tier like 1Gb and something slower, or your paying for 1Gb an the ISP has not ensured the modems is locking into 32 channels which some ISPs need for 1Gb speeds.
I see lots of errors on the modems logs something the ISP should look into...

with an ethernet connection to the modem. It works great until it drops.

Re: cm1200
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 them back ON.
