Hi. Some brands of radios talk in their own proprietary 'language'. The ePMP radios by Cambium normally speak only 'ePMP's TDD' language. There are SUBSTANTIAL benefits to ePMP's proprietary language - - and in fact, the reason Cambium made ePMP, was to address the shortcomings with WIFI and other TDMA implementations.
But - in TDD mode, they don't interoperate with WIFI or other bands of radios.
That being said - there are lots of experienced users on the forums, and a number of us would be pleased to help you try to diagnose and rectify what problems you're running into. Post screen shots of your CONFIGURE -> WIRELESS screen as a start, and we can go from there.
No - a Force300 radio and a MikroTik radio will each speak their own different (and incompatible) language.
That being said - there is the 'ELEVATE'' software which Cambium has created for some UBNT and MTik radios. ELEVATE software basically replaces the UBNT or MTik software with a Cambium flavor of language. I don't know if that would work for your situation or not though.
If it was me, I'd be much more likely to just link Force300~~~Force300 and then MTik~~~MTik, rather than trying to figure out a way to connect incompatible gear together. Or I'd buy 1 more F300 (or 1 more MTik) to help simplify the link.
So, it (maybe) is possible that 'maybe' the Elevate software might be a way to accomplish this? But really, if it was my, I'd re-arrange the hardware so that F300's were pointing at F300's, and that MTik was pointing at MTik. :)
