ndis0: link down after idle time

I am running FreeBSD 5.3-stable and have had limited success with a
d-link DWL-G520 card, rev B3 (atheros ar5213 chipset). I had hoped that
I would have purchased a card with a supported native driver (ath), but
alas! The card was supposed to have used the 5212 chipset, which is
supported by the ath driver. The ndis driver will only bring the link up
if the media is forced to adhoc mode, which seems to be common from my
limited viewing of reports in the mailing lists. The card works well,
albeit only in 802.11b 11mb/s adhoc mode, but there is a major problem
that I can't figure out. After about an hour or so of idle time on the
link, the interface brings itself down and cannot be resurrected unless
I issue a command through ifconfig to bring the interface up again. Does
anyone else experience this problem and/or have a solution? Attached
below is all pertinent information I can think of:
