on 802.11b the signal works only for 5 or 10 meters, if I use o Mini pci
prism sl 2511 mp plus 2.10 I have a very goor and long range of a lot of
Km… Why? Is a problem of setting of minipci ?? it possible to have a correct setting of wireless on mikrotik interface?

CM9 has less output power that PRISM, can you post your wireless configuration so we can welp you more? a tell us what type of antennas, pigtail, etc do you use, and what version of MT you have installed.

How I can do for the CM9 minipci?

First upgrade to 2.9.12, then try again with the CM9. The CM9 is atheros based chipset so the configuration is diferent. Post the results after the upgrade

I have upgrade to 2.9.12 but I have not a good test!!!
I have the problem too…
If I test by minipci Wireless miniPCI-Module Compex WLM54G ??
