Seems to be good workarounddrixster, will putting the AP in a bridge and run your stuff off bridge?
Bridge is always up.
It's already investigating by Mikrotik support (Ticket#2008122966000358)we need your supout.rif file to see the cause of the problem, forum reading is not enough. also - forum is not a support system, we don't read every post.
Yes, on wireless too. But on WLAN I don't have as much IPv6 traffic. Anyway, I don't see any influence on router's load.
