    v16 v17  
    5555I managed to cause a SBP by changing channel while interface was up. To fix it, change channel on start-up before interface is up and it appears to be fine.

    6157After suffering repeat kernel panics on my SMC WPCIT-G, I have done the following:

    7470Turning off background scanning with an 'iwpriv ath0 bgscan' removed all stuck beacon messages from my server.  My configuration is set-up with only one VAP in master mode running hostapd on a gentoo amd64 box.  I was getting about 200 stuck beacon messages per minute before turning off background scanning while idle.  I have not had a chance to test under load yet.

     73I stopped getting those "stuck beacon" messages after setting the following commands: 
     74 iwpriv ath0 bgscan 0 
     75 
     76 iwpriv ath0 protmode 0 
     77 
     78 iwpriv ath0 rssi11a 11 
     79 
     80 iwpriv ath0 rssi11b 11 
     81 
     82 iwpriv ath0 rssi11g 11 
     83 
     84 iwpriv ath0 bintval 500 
     85 
     86 sysctl -w dev.wifi0.diversity=0 
     87 
     88 sysctl -w dev.wifi0.txantenna=1 
     89 
     90 sysctl -w dev.wifi0.rxantenna=1 
     91Changing the channel to 8 increased the speed. I've set mode to auto (iwpriv ath0 mode 0). HostAP is running in "G" mode. Turbo mode is enabled.
