I'm running a total of 3 WRT610N V1 with eko 2.6 builds.

I've occassionally seen this message in the past, but since I've upgraded 2 of the 3 devices to 15943, I'm seeing it much more frequently:

Build 15508: happening every few hours
Build 15943: happening very frequently, about once every 10s

All devices are used as Access Points only, not as Routers. The WAN port is used as a LAN port by means of VLAN configuration.

I've not yet seen an actual problem related to the errors, just wondering.

Best Regards,
Olli

I too am seeing those messages. What's prompted me to come to this forum is that they're happening every minute now.

What's changed:
- I bridged my PC's wired + wireless NICs (wired is plugged into U-verse set-top box, which loses network connectivity almost once a week, require a power-cycle. WLAN connection provides a modicum of redundancy).
- My Linksys E3000 started acting "screwy" (hi-tech term there). Our laptops are randomly able/not able to connect to the G radio; N radio connections unaffected.

N.B. in the network switching world, you will sometime have the firmware/OS complain or "notice" that a packet is attempting egress OUT of a port for which the firmware/OS believes the MAC already resides.
