FreeBSD 4.9 wi0 not working

[Michael Sierchio]

Box A:	FreeBSD 4.9-RELEASE AP, Netgear MA401 (Prism) card in hostap
mode, authmode shared -- this works with Box B, WindowsXP client but
not FreeBSD client -- driver?

The same Box B hardware (incl. the same Netgear MA401/Prism)
running 4.9-RELEASE works with the above AP if I set the authmode
in each to OPEN.

If someone can explain, I'd be grateful, or at least
simulate gratitude with all my heart.
