RT-N66U dropped connections

[Vaporhead]

Hope ya'll can give me some info. I've been losing my internet connections for the last 3 months. Cox communications have been out at least 4 times and they keep saying their lines are good.

I logged into the router and get the following in the log. It repeats this numerous times throughout the day. What does it mean? Also, I reverted from the most current firmware back down to 3.0.0.4.374_4561 thinkin that would help, nope. Any help would be appreciated.

This indicates that the Ethernet connection between the modem and the router is dropping. Most of the time it's the modem that's crashing and rebooting itself.

 

[Vaporhead]

That's what I was thinking. They've replaced the modem twice already. I have all knew wiring in the house to this modem now too. Any chance some sort of interference could cause the cable modem to drop out?

 

[RMerlin]

Unlikely. Have you looked at the power supply and electrical plug where the modem is plugged? Could also be a defective port on the router.

Check the signal levels in your modem to make sure they are within spec.

I have good signals. Is it possible for the router to cause the modem to reset? I had to have this router repaired once before because the WAN port no longer worked.
