CM1000v2 Cox Dropping Internet Connection
Good morning folks. I have been having an issue with my Cox service for quite sometime. The internet will just "vanish", but the Eth0 & WiFi will continue to work fine. At first, thought it was our r...
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Power is too high:

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.

FURRYe38 - I love the "canned message" on all your responses - LOL. With the amount of times I've read it, I can almost repeat it my memory - LOL HA HA HA I read that a couple months back before I called in for service, and the contractor did in fact test with his meter, and said everything's okay. Now whatever that means, who the hell knows.
Also, there are no splitters or anything. I have a line that goes from the Tap in the Ped about 5 yards tops from the house (which is the line the contractor replaced), to the J-Box which there's only two lines in there. One for the Cable Modem which is right inside the house from the J-Box on about a 4 foot line through the wall, and the other connection which is UNPLUGGED is to the On-Q box in the laundry room, which is unplugged because we don't use anything Cox other than the modem right inside the house from the J-Box. The tech unplugged the Splitter in there and just threw a barrel connector on the lines.
So you are saying the levels I posted in that PDF are too high? What should they be roughly, for someone who is only about 5 yards tops from the Tap with no other devices in line from the Ped Tap to the Modem?
Yeah sorry FURRYe38. I saw your link, read it as I was typing, and completely forgot to take that out of my post.
So if Cox comes back and says, "Oh - those are completely acceptable", then I guess it just stays sending too much power (two times the acceptable amount according to Netgear), and we just deal with the internet vanishing every couple days... UGH!
I mean I don't know what else to do other than wake up Mon, Wed, and Sat and power cycling the modem to get it to last a couple days.
Now granted, with the amount of new housing and businesses growing here in North Phoenix, they are constantly adding / reconfiguring head-ends, so I guess best case scenario, is open another T-Ticket and ask for an In-House tech this time?
