I believe I read somewhere that 802.11b standard supports larger MTUs =
than 1500.
I know basic ethernet MTU is 1500 but even my crappy old Nortel 8603 =
routing switch supports up to MTU 1960

Any corrections appreciated

Because the maximum size of the data poriton in a frame for 10Mbit and =
100Mbit Ethernet is 1500.

Not unless they change the standard. I believe 1Gbit Ethernet is =
slightly different but would have to look up specifics.
