    236236In the last 3+ years we've used various versions of madwifi (currently 9.3.3) in dozens of 5.8 Ghz multi-node installations. We've never come across the SB problem until our most recent installation which is running on 900Mhz using Ubiquiti SR9's in what turns out to be a very high-noise environment (indicated noise floor around -75). We were able to eliminate it there, by increasing the beacon interval to 1000 msec from the default of 100 msecs (iwpriv wlan0 bintval 1000). However with the high noise floor, and packet loss approaching 95%, we still don't have an operating system, but that's another story. We will try to address that problem by upgrading to XR9's. 
    237 Update: XR9s and horizontal polarity on the antennas took care of the interference problems for the most part. However it was still necessary to set the bintval to 1000 to have a stable system.
