I have found the senao/engenius 200mW (MMCX) card to be fine.
Note, almost invariably, the Firmware will need to be
upgraded or downgraded to work on m0n0wall.
The only Senao F/W "known" to work is the Primary/Station
releases 1.1.1/1.5.6 - note, use the How-to, don't break the card.
I found the most practical approach for me was
to use (I hate...) Windows XP laptop.
Engenius provides a program, it can probe current F/W, etc.
My m0n0wall now reports the following....
