    I'm really glad google brought me here. I've been trying to find out the cause of this for months. Asus tech couldn't answer my question.

    My question is. I've been chasing a router reboot issue. It likes to reboot under heavier usage. I have the AC66U and I would get crazy numbers like this snipit from my log

    could this have been adding to the workload and causing my reboots? I've gone through 2 RMA's and they actually sent me different ac66u all have the same issue. And all were tested good by Asus.

    I think I'll enjoy the site.

    my transfer speed has gone up from 1.5MB/s to 12.5MB/s wirelessly.. so I'm guessing this was putting a lot of extra strain on my router and could contribute to the rebooting

    I think I just found this - I was installing the latest ASUS firmware, and I switched on IGMP snooping on both the 2.4Ghz and 5Ghz 'professional' tab in the wireless settings. I got a heap load of these exact messages - switching the option off didn't suppress them until I rebooted the router.
