recommended miniPCI 802.11a/b/g card for Soekris net5501 running FreeBSD 8-STABLE?

[Graham Menhennitt]

I've been trying to get reliable wireless AP functionality in my Soekris
net5501 (http://soekris.com/net5501.htm) box for some time now. In the
past I've reported a problem with it
(http://www.mail-archive.com/freebsd-stable@freebsd.org/msg105623.html)
that causes it to report "ath0: stuck beacon; resetting (bmiss count
4)". I can minimise this by increasing the count but I still get the
problem and the wifi connection is patchy - dropped connections, and low
transfer speeds. So, I think the easiest solution is to get a better
card. Can somebody please recommend any such miniPCI board.

My existing board is a Wistron Neweb CM9 miniPCI wireless card,
802.11abg which is based on the Atheros AR5004 chipset.

Some cards that are easy for me to get are the Wistron Neweb DCMA-81,
5006 Super AG Atheros 6G which uses Atheros AR5414, and Senao NMP-8602
PLUS-S / EMP-8602 PLUS-S which uses AR 5006. I can probably source any
others that anybody can suggest, too.

I'm not after super speed or range, just reliable performance in a
net5501 running FreeBSD 8-STABLE and acting as a wireless access point
using WPA2.

Thanks for any assistance,
  Graham
