Where do I get this patch?  I am willing to try.  I am using ubuntu 
10.0.4 LTS.

Please add it.  It works great for me.  Jounie recently added it to 
wpa_supplicant.  I think I am using version 0.7.1. or 0.7.2? with this 

freq_list=5180 5200 5220 5240 5260 5280 5300 5320 5745 5765 5785 5805 5825

I have done detailed throughput testing and in my environment at work 
this gives me consistently 2x better throughput besides allowing me to 
troubleshoot either a 2.4ghz or 5ghz issue at my choosing.

No ...haven't tried, and won't bother until it allows forcing 5Ghz.  If 
you do add this feature to NM I would love to know when it is available.

Win Vista, and Win7 do this now on a per SSID basis.  Mac OS still lacks 
this ability.

Very nice.  Thanks for the info.
