Don’t care about capsman just want the best performance.

No reply from Mikrotik yet 
Lately we have received couple of questions about Wireless-cm2 and Wireless-fp differences so thank you for bringing up this topic.
So wireless-cm2 package is made for CAPsMANv2, of-course, but sometimes there are few updates which we put only in wireless-cm2 package, generally they are very insignificant or made for specific request e.g. country regulation setting.
In normal conditions there shouldn’t be any differences. If wireless performance differs between these packages you should write to MikroTik support.
Special case is when UAPSD (Unscheduled Automatic Power Save Delivery) client is connected to AP then with wireless-cm2 other clients throughput may reduce, well that’s because wireless-fp even doesn’t have support for UAPSD clients.
