brcmsmac driver only works when sitting next to the AP

[Roland Vossen]

Hello Camaleón,

I did not see anything unusual in the provided 'ps -A' output.

I want to find out what the result of a scan is, specifically the RSSI. 
In that way I can judge if this is a signal reception problem.

Can you do the following:

- unload brcmsmac driver (or simply don't load it)
- 'sudo service network-manager stop'
	.. this gets network-manager out of the way, perhaps it is related to 
the 'resource/device busy' message
- load driver
- 'sudo ifconfig wlan0 up'
- 'sudo iw wlan0 scan'

Thanks, Roland.
