I'm attempting to select a T43p and am concerned that
I don't really understand 802.11 compatibility.  It is
obvious that a machine with 802.11abg hardware is
compatible with wireless connection points/routers/etc
that use any of these protocols.  But, if a laptop is
stated to have only 802.11g would it be able to connect
to other hardware that was only 802.11b compatible, for
example?  In otherwords, can the 802.11abg fall back to
the other protocols on its own, while the 802.11g would
depend on the other end of a connection to include its
protocol?

I look forward to your answer(s).

Thank you!
