Depends on the AP, some you can limit to only allow clients to connect at
given speeds or at specific modes, 802.11b or 802.11g, etc.

Some B/G APs can have clients connect on both B and G at the same time,
and those clients are blissfully unaware of the other clients connected
at the other speeds...

These APs will try to slice up the talk time to those APs at B or G at
the connected speeds, but retransmissions become a real problem.

To the point where its better to run two APs on the same channel, one
on B and one on G...

Thus spake the Lord: Thou shalt indent with four spaces. No more, no less.
Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
