AC1600 C6250 Internet connection drops intermittently

Question

I purchased this cable modem back in early July and within the last few weeks it seems to be dropping the Internet Connection often (3-4 times a day). I took a snapshot of the Event Log and Cable Connection power info to see if that could shed any light on an issue. If I reboot the router the connection comes back, but it's annoying when I'm in the middle of doing something online and I have to do this. Is there any solution or do I need to try and return the unit?

who is your ISP? ( I am guessing it is not Comcast).

you Upstream (US) power is reaching its limit (51 dBmV) and your ISP does not want to enable extended US power for your device. Most likely the issue is on your line by the ISP and they need to tune your cable to reduce the US power from the Modem.

yes, mention them that you need to REDUCE YOUR UPSTREAM POWER. Ideally it should be in low 40s but yours is MAXED out to 51dBmV.&nbsp;&nbsp;It the same event log what you posted before but unfortunately you posted partial screenshot. I need full screenshot.&nbsp;&nbsp;if COX does not help you, PM me.&nbsp;

Any suggestions? I've lost connection so far twice in the last 6 hours.&nbsp;

I use Cox Communications. Should I call their support and mention what you wrote about the incoming power via the cable connection?&nbsp;Is there a place that the Event Logs exist in file form? I just see Event Logs in the Administration&gt;Event Log window. Here's a snapshot of what I am seeing there.
