Hello,

Recently I upgraded to 6.2-REL and have had massive problems with
our WPA-PSK AP in my office:

May 31 15:05:55 rebelion kernel: iwi0: link state changed to DOWN
May 31 15:06:03 rebelion kernel: iwi0: link state changed to UP
May 31 15:06:06 rebelion kernel: iwi0: link state changed to DOWN
May 31 15:06:14 rebelion kernel: iwi0: link state changed to UP
May 31 15:06:18 rebelion kernel: iwi0: link state changed to DOWN
May 31 15:06:26 rebelion kernel: iwi0: link state changed to UP
May 31 15:06:31 rebelion kernel: iwi0: link state changed to DOWN
May 31 15:06:39 rebelion kernel: iwi0: link state changed to UP

the iwi0 interface was from time to time nearly unusable. It turned
out that sometimes near our building other small companies
appeared on air. I don't really understand why they can be seen
only sometimes with


$ ifconfig iwi0 scan
SSID            BSSID              CHAN RATE  S:N   INT CAPS
mywifi  xxxxxxxxxxxxxxxxxxxxxx:0b   11   54M 56:0   100 EP   WPA
default xxxxxxxxxxxxxxxxxxxxxx:eb   11   54M 37:0   100 EP  
SCHLxxxxxxxxxxxxxxxxxxxxxxxxd6:cc   11   54M 31:0   100 EP  
SCHLxxxxxxxxxxxxxxxxxxxxxxxx21:84   11   54M 31:0   100 EP  
SCHLxxxxxxxxxxxxxxxxxxxxxxxx21:87   11   54M 31:0   100 EP  

and sometimes I only see my own one 'mywifi'. Any way, since I've
switched my AP to use channel 7 all is fine now. Just to let
you know in case others have the same trouble.
