Re: Wireless network with bfwm sometimes works and sometimes doesn't

Thank you so much for the hint, now I understand what the debug option does. I have actually tried it, but, because `man ifconfig` says "this turns on extra console error logging", I incorrectly assumed that it would output to stdout or stderr, not to the system message buffer. Then, calling ifconfig from xterm, I couldn't see any debug output and wondered why the option does nothing.
Anyway, here is the result of `dmesg | grep bwfm0`. Vodafone-7D3A_5G is the one I try to connect to, Vodafone-7D3A is same router but different frequency, as for the others, I assume that they belong to my neighbours:

I would appreciate any suggestions.



Show us what is printed in dmesg with debug enabled when it fails to 
connect.



Among other info it shows scan results. Does your AP appear in the 
list?
