Slow WiFi with RT-N66U and 374.43

Do you have a wireless extender/repeater connected to the router?

Nope. Basic wireless setup w/nothing special. No IPv6, VPN or Dual Wan, etc. being used either. Going on 15 hours now with .42 and no issues or no more error appearing. We'll see if we make it past tonight. Thanks.

In which case those messages are usually caused by a wireless client switching between the 2.4GHz and 5GHz access points.

Hmm. That's good to know. I'm using different SSID's for 2.4GHz and 5GHz and most of my devices are and have only been associated with the 5GHz band. I don't think it's a case of the client switching between bands as they aren't associated with the opposite band. The slowdowns are noticed on 5GHz.

Nope, my 5GHz radio is switched off.
I still see these messages, but not that much.

Then I'm out of ideas. The message relates to the forwarding database of the Ethernet bridge. eth2 being the 5GHz adapter (on the N66U).

So it's saying eth2 is seeing something that it has previously seen on one of the other interfaces. So unless you've got a device connected by wire and wireless at the same time...

For what it's worth ... I was running TomatoUSB for 6 months on my N66U and had no major issues. My best uptime was 70 days. Then I switched back to AsusWRT-Merlin (full NVRAM reset) and saw improved performance on the Wi-Fi, but a few days later, suddenly none of my devices could connect on 5GHz. The Mac Pro said it could not connect, but there were no errors in the console log. My AppleTV just gave a general error.

I checked the N66U's Wireless Log page and saw that no clients were connected on 5GHz, but the network otherwise appeared to be "up." The 5GHz light was turned on at the router itself. There were no errors in the router's log to indicate a Wi-Fi problem.

I rebooted the N66U and every device could connect again.
