Actually I was gonna write about MikroTik but thats not true. I also use 
MikroTik and it doesnt support all the frequencies. It doesnt even have 
country selection. I think StarOS is able to unlock the cards somehow. 
But MikroTik shows only the frequencies that the card can support. For 
example in MikroTik, I am not able to use channel 14 of 802.11b but in 
StarOS its visible with the same card. I never tried if it works though.
