R7960P repeatedly stops service for brief time

Router interrupts service frequently (a few times every day) for very short times (some seconds to one or two minutes), then resumes normal operation. This happens also on pure local connections.

R7960P Firmware 1.4.4.94, ISP COX, Modem SB8200

No LED color change (all white) when problem occurs, incoming (Modem) LED on router keeps flickering as usual. All Ethernet cables are Cat.6 and tested.

Symptom: Established connections to external and internal hosts freeze, browsers report "server not available" or similar. Clients are connected wired and wireless. Client OS are macOS and Linux.

These interruptions were originally observed on connections to external sources, but recently also between (all wired connected) macOS clients and an internal server also wired and on macOS.

Anny suggestions?

Thank you

  • Can you get to the routers web page when this happens? 

    Has a factory reset and setup from scratch been performed?

      Caught this internally only one, unfortunately, the router page was not reachable for a moment then.

      A factory reset was performed when reinstalling the router a while ago, firmware was then 1.4.3.88, and as I recall no disconnects had happened then. Unfortunately I missed that the auto-update flag was set. To my kind of observation, this problem may be associated with 1.4.4.49.

      I have (need) a substantial DHCP reservation table, so was hesitant for extra factory resets. But m

        Whenever something like this happens to hardwired devices too, I'm always starting back at the modem. Try hardwiring a PC into the modem and use it for a while (long enough to see if its the issue). 

        You can also pull the modems logs/connections links to see if its the issue

    Do you think going back to 1.4.33.88 might be worth a try?

    Thank you very much
