I was doing some tests where I change the AP's configuration
(enable/disable HT, enable/disable HT40, etc) on a somewhat
hacked 3.7.9+ kernel.
One thing I noticed is that if stations are associated using /a,
but I quickly reconfigure the AP to use /a/n mode (ie HT enabled),
the stations stay in 'no-ht' mode.
If I down/up the stations, they come up in HT mode.
Just a curiosity at this point...
Thanks,
Ben

You probably didn't flush the scan cache on the stations before
reconnecting after the reconfiguration.

No..I didn't..didn't do anything in particular to the stations
at all..just let them re-connect on their own.
Thanks for the explanation.
