Constant Internet Outage/Cable Modem Needs Reboot
I have the following log messages as it constantly disrupts my internet service. It continues to repeat the critical error messages.
The cable modem is Arris SB6141 and my home service is 100Mbs service. Its connected to Apple Airport Extreme AC for WiFi and NAS.

Called service and got really unhelpful go dos over the phone - unplug, disconnect, wait for 15 seconds, and so on. No real solution.
The problem happened several months ago, while there were some large maintenance activity, then started being more reliable but then this past week, it has been a mess.
Any ideas to fix?
Thanks in advance.

What are your modem's signal levels? Can find them at 192.168.100.1
Also, what firmware is your Airport running? Apple recently released a patch 7.7.7 that fixes a few things, including Cox IPv6 issues. See post here and see apple support article here.

This is the Cox signal, not the modem. It has to be. I have the same problem with the netgear N450 straight from Cox.

Please stop copy/pasting the same post in multiple threads. Just because your having a problem doesn't meant its effecting everyone in the entire country. This is a public national forum. Please don't post misinformation.

The Airport Extreme firmware is the latest released this past week, 7.7.7.
As for signal level, S/N is all at 38dB.

I'm not sure what you mean by this. I just registered yesterday and this thread is my first ever post here....
If others are posting the similar issue, then its clearly not a unique problem and not misinformation as you claim.....
Clearly not everyone is having the issue but there are some that are. How nice for you that you not having to deal with this issue....

He was talking about Angelpie's comment, which she has copied/pasted into multiple unrelated threads.

Are there any splitters on the coax cable that connects to the SB6141? Have you run a test without the Airport to see if the connectivity issues continue? Connect a device directly to your SB6141, reset the SB6141, and then get back online for a while. Can you describe what happens when you notice that your connection has dropped?

There is no splitter. Goes from wall to the modem. Its my modem but Cox installed it when I signed up for the service 14 months ago.
I have never connected directly to the modem. The indication of a problem is that nothing updates on the website/cannot goto a new site when it goes down. It logs the same error messages as posted originally but the status shows that the cable modem is Operational.
Unfortunately, since the problem is erratic and periodical, I never know when its working or not....
Its configuration is:
IPv4 Only

I'd suggest trying a connection directly to the modem just to make sure there isn't something going on there. If that doesn't work it may be time to see about having a tech come out and troubleshoot further.
