I want some suggest about the best mini-pci card for 2.4 and 5.4-5.7 frq
I try cm9 and ubiquity sr5 but with other mini-pci card I have a lot of problem of signal quality and sensibility.
I want to try other card but I don’t now which ..
The best cards I have tried are the ones dirrectly from MT.
Not a plug, just an observation.

I’ve had really excellent results with SR2, SR5, and CM9. Perhaps you are not being anal-retentive enough with your cabling/antenna placement?
We still swear by the the CM9 as they seem to be the least problematic (for us)…for both 2.4GHz and 5GHz although sometimes a Senao 200mW card performs better for range with 802.11b in low noise areas.
A lot of people overlook using quality pigtails - this can make a huge difference, especially with the 5GHz band.
Apart from that I assume you just want to sell them (with several posts like this one in the last hours):
Can you give some facts/test results to prove your statement? 
Best regards,
