Thats the bug! I've upgraded all the way to 6.11 but cant get away from it!
I'm not doing anything fancy with the CCR but this is exactly the bug I'm
experiencing. When I switch over to my 1100 the issues go away. I hope
Mikrotik gets this fixed soon! Thanks for the post!

After scratching my head for a day I just figured out what is causing these
support calls where nothing seems wrong except the user cannot get online.
Turns out the CCR I have routing this part of the network is experiencing a
bug in the ARP table. For whatever reason, customers would get an IP
assigned but that IP address had a different MAC attached in the ARP table
on the CCR. Delete the entry manually and it immediately adds the correct
one it and everything is fine. The ARP timeout is set to the default and
lowest possible 30 minutes.
A forum search for 6.x ARP bug found this report of the same issue.

Just a heads up for anyone running 6.x out there. I am on 6.5 on this
router and I am not changing it due to the other stories about later
versions. I will keep an eye out for a bug-fix first.
It would be interesting to see if setting:
/ip dhcp-server set dhcp-server-name add-arp=yes
If that at least works around the problem, then you may be at least a
step in the right direction.
