No authentication.
All devices running OSPF are supposed to be use the same NTP server, but
this certainly something I will check.

Basic questions but needs to be asked:
* does ospf have authentication keys set?
* system clock 100% in sync across all your devices?

Subject: [Mikrotik] Customer Traffic Stops
I have about 3 APs that have customers with the same issue. All the APs
in the network are MT ROS 3.30. CPEs are all MT, but various version,
predominately 2.9.51, 3.11, 3.30.
All APs are running OSPF and are on the backbone. At each tower there
is also an OSPF area for the tower. All APs on the tower are in the
tower area. Most CPE on a tower are running OSPF and are in the tower
area. CPEs that are not at ROS 3.30 are running RIP to the tower.
Occasionally and at random issues, traffic will stop flowing to/from one
or more customers. Usually going into the AP registration and dropping
the registration corrects the problem. Sometimes that does not work,
but disabling the AP wireless interface for 5 seconds and the
re-enabling in clears the problem.
It is probably not a hardware problem as all the hardware on the AP end
of the worst offender has been replaced and made no difference.
One AP has 2 radio cards on board. Only one exhibits the problem. The
other never has. (I do not need advice on not putting two radio cards on
the same card. This worked for a long time and only one site is
configured this way.) The other 2 that I know have the problem do not
have multiple radio cards on the routerboard.
Two of the offenders are running 10MHz channels, the third is running b
only.
Processor utilization on all routerboards stays below 30%.
I am looking for some suggestions for things to look for. It seems
really odd that 3 of 60+ APs would have the same symptoms and the rest
never do.
