I doubt you have a modem failure. I've
never had a modem fail, and very few do - rather they are usually
replaced because 1) someone missed a level issue somewhere, 2)
they were blew out with lightning, or 3) you wanted a docsis 3.x
modem for better speed.
You probably have some coax teetering on the verge of being crap somewhere, like a central conductor sucking out, and just barely left conducting. Hot in the day, cold at night, think about what that does to metals, ie expansion/contraction, work hardening metals. Some just snap in the insulation. AZ is rough on coax with extreme heat as east-coast extreme cold is. I still say you have a bad connection between the modem and your ped (outside). Take the modem and a laptop to your external box if you can, remove any splitters direct to the line, power it, and check your levels on the internal page there. If they don't improve, the issue is from the ped to your house, not inside. Or call cox and have them check your levels as you do, you might need "advanced" support to do that as the first-level folk are barely sentient these days to speak full sentences. Last time was the aforementioned missing/undocumented splice in my coax outside at the neighbor house became an issue, cox told me to replace my modem after checking at my house by a contractor. Begrudgingly I did, got a new docsis3.0 at the time, and same shite, random drops and 30% packetloss after an hour. That's when I got an escalation, and a cox field tech supe came to my house ready to tell them to start trenching my street to replace it (my ped is across the street, yay). He checked at the outside, and found levels to be terrible still, and literally had to dig up my yard and my neighbor's to find the missing joint. Replaced the ends, new joint connector, and my connection was rock solid again. Anything spotty like that is a physical issue in coax, I will put money on it. Been dealing with cable modems since working at @Home in 90's. Getting a 3.0 modem has advantages too - the 2.0 channel space was legacy from old analog days, working around old crap and left to die, and the 3.0 channel space is net-new, though any new modems are such and use that these days. Newer 3.1 units use the 24/8 downstream/upstream channels for better throughput (newer tech uses channel bonding to span physical links for more bandwidth), which is being deployed to give gig-capability, downstream at least (max upstream is ~245mbit/s). -mb On 02/27/2015 09:14 PM, Mark Phillips wrote:
