Arris modem out of sync - precisely 48 hours apart

The message coming in at the same time is because it happens only at times when the DHCP lease renews, which appears to be 48 hours. I don't know what it means, but I know that it is not impacting. I didn't have any packet loss when getting those errors myself. I don't know where official documentation from Arris is to elaborate on cause, but don't worry about those messages.

Oh well. Thought I might have something. Still don't know what's causing that computer to keep losing connection. Maybe I'll change out the wifi card this weekend.

Been seeing lots of this lately. Anyone else. A few people i know are seeing it also. Seems like internet just stops working. Along with the dhcp one

TLV-11 - unrecognized OID;CM-MAC=00:1d:d0:**:**:** ;CMTS-MAC=00:01:5c:49:6e:48;CM-QOS=1.1;CM-VER=3.0;

I get these sort of errors all the time, on my brand new Arris modem. These errors seem to lead to a loss of internet connection, resulting in the need to power-cycle...sometimes, the errors come and go without necessitating a complete restart, but they certainly have a negative effect on network performance.

In addition, I have nearly constant visual artifacts on all of my cable boxes as well. Some channels are intermittently black, most often Discovery/Learning, Speed TV, and the History Channel. Sound will often skip and sputter, and the cable boxes freeze fairly often (more than once a week).

I have had many technicians in my home, and the supervisor for my area is in my rolodex. They all claim that this is either normal operation - or that any one of a number of things are at fault. To date, they have blamed my problems on 1) electrical interference from wall outlets 2) stretched wires from hurricane Sandy 3) the cable box and.or modem being too warm 4) bad splitters 5)loose wires at box terminus 6) bad run from street to house 6) HDMI wire
7) electrical interference from a neighbors home 8) temperature fluctuation related to weather.

Cablevision's monopoly has insulated them from competition for too long. Whatever the root(s) of these issues, they have lingered for years, through multiple generations of equipment.

The DHCP Renew Warning has been discussed here previously. The warning can be ignored.

If you're truly having problems, send an email to Wilt (search the forum for his email address). He'll get you fixed up.

Nope, it's not that serious yet. When it gets worse I will

If it's only some PCs in the house and not others, don't bother Wilt because it's an in-house issue.

It's all of them, but not at the same time. I haven't changed anything in the house. I do suspect ill timed resets on the modem, because I had to refresh the wifi printer, and both NAS drives stopped communicating with the router. All of this happened in the same time frame. The router doesn't show anything unusual.

You have a problem with your own network.

You know, it's funny. On days when we see lots of video and audio dropouts on cable, we have more issues with computers that keep dropping connection. When we don't have dropouts on cable, we don't have them on the computers, either.

Just saying

FYI, I just checked the modem log, and the DHCP Renew Warning stopped a week ago. I haven't changed anything on our network. So what does that mean?

It means the DHCP renew warning can be ignored. Even if it was occurring every day, the warning can be ignored.

FYI i notice this everyday at 3:43am, going back to the 2/7/2013 and I am on static BOOL in Fairfield, CT.

Doesn't affect connectivity (maybe because we have to connections as well with failover) but just thought i'd throw that out there.

It must be magic!

I've gotten these every so often, along with T3 timeouts, for years.

Still don't know what causes it, but most of the time there's no issues.

Arris modems NOT out of sync - it's just DHCP renewal, doods
