Daily Motorola modem reboots, T3 timeouts, upstream power level issue?

Hi Chris - that's kind of what I was thinking. Let me know how I can facilitate.

Other thoughts for the record:

• I've read elsewhere that heat may degrade signal on older coax. Since my modem resets around the same time every day I started wondering if some older cabling is getting hit by the sun at that time. I've looked around the house but haven't found anything obvious.
• I've also read that signal amps with active return may resolve the problem, but didn't want to go there without checking the basics first (such as a visit by a technician).

Thanks for the help.

God luck, took me a year, three gateway upgrades and cox blaming faulty equipment to fix the problem. I did everything they asked for a solid year and it ended up being the trunk/node. they much rather have spent over 30 hours in field tech services rewire a house 2x then to ever check the Node/ Trunk which is what T3/T4 is referring to. 

My node was split about a month ago and have experienced zero of the problems I had before. Good luck getting someone who actually wants to work for you on the phone. It took me a year of headaches and dropping service to finally get someone on the phone to escalate the issue. 

Thanks for chiming in Diskrete, and sorry it was such a hassle. This was my own fear having been through something similar with other service providers.

The Cox tech came out this morning and replaced my coax connector from the wall to the modem. He also disconnected some old splitters I didn't know were out in the box. Since then there have been no new errors in the modem's logs, including during the time of day when the modem was rebooting itself. It's only been a few hours, so it's too early to tell if it's truly fixed, but the initial indications are good.

Don't spend any money and don't listen to Cox when they try to tell you that the problem is on your end.  The problem is with their signal.  Mine drops out constantly and I like many others have spent a small fortune trying to fix a problem that wasn't mine to fix.  There either needs to be some kind of real resolution to this, or there needs to be a legal remedy.

Don't know if this will help but my Motorola was slow and intermittently dropping the connection every 10 minutes or so. Tried everything I knew and then noticed that I have moved some boxes near [on it] and when I took them off the modem was very warm.

Put it in a well ventilated place, cooled off and since then [4 days] zero problems.

Update:

• The outage I was getting about the same time every day hasn't recurred.
• Still seeing errors but way fewer. Less than 20 rows in the logs and only a few T3-timeouts since repairs done on 5/23. No log entries whatsoever since 5/24 (currently 5/27)
• Signal levels are improved and holding steady. Downstream levels hover around zero dBvM. Upstream consistently in low-to-mid 40s.

New hypothesis: Old splitters were diffusing the upstream signal just enough to trigger modem reboots. Why it was daily around the same time I can't be sure. Possibly when the sun hit the box on the house? I may never know.
