Sorry for the winging. In the sta-side case you don't need "mode 11b"
if the ap is 11b-only; you only need it if you want to force 11b
operation when talking to a b/g ap. This can also be done by locking
down the channel spec with "channel 6:b" (works for both sta and ap
The mode knob just controls the set of channels placed in the scan list
and is mostly useful to constrain operation of multi-band cards and/or
to reduce scan time (which can also be done with the chanlist control).
There are techniques we could add to make scanning super-fast but they
require proper roaming support which isn't feasible w/ the current
quality of our drivers.
On the ap side there are "pureg" and "puren" knobs for constraining
operation as 11g and 11n channel specs are bi-modal (b/g and legacy/11n).
