netgear ma311 failures (wi0 driver)

Hi,
 I bought a new netgear ma311 about two weeks ago and set it up as an
access point http://www.unixcircle.com/features/802.11b_freebsd.php on
my 5.0-RELEASE box.

 It is working very fine, when it works. It has crashed 3 times now
since I've set it up. When it crashes, the box is blocked and I can't
ssh in or login from the console. Sometimes pings get through, but
mostly not (all from a wired box, btw).

 Here are some of the logs:

 Here is the script that I use to initialize the card:

# ---------------------
#!/bin/sh
#
# configure the wireless interface
ifconfig wi0 inet up ssid my_wifi media DS/11Mbps mediaopt hostap

# set the IP address and netmask of the wireless device
ifconfig wi0 inet 192.168.2.1 netmask 255.255.255.0

# turn on wep
wicontrol -e 1

# add 128-bit wep keys (bogus keys just for this post :-))
wicontrol -k 0x24598530c7e81f36ec6fdcee19 -v 1
wicontrol -k 0xb69954545d9d17f7499527e873 -v 2
wicontrol -k 0x757904ed9cbc7acde7be04d817 -v 3
wicontrol -k 0xc514bfbeaa6abb24b86bd6ad81 -v 4

# use key 1 to encrypt transmitted packets
wicontrol -T 1

# choose a non-overlapping channel (1, 6, or 11)
wicontrol -f 6

# define the station name
wicontrol -s "FreeBSD_AP"

# bridge the wireless interface to ethernet
sysctl net.link.ether.bridge=1
sysctl net.link.ether.bridge_cfg="wi0 xl0"
sysctl net.inet.ip.forwarding=1

## EOF
# ---------------------

 I'm connecting to the AP with a netgear ma401 that's in a win2k laptop,
using the driver from netgear with their wep. If I can get this problem
to go away, I'm going to enable the IPSec (I already have it working
between win2k and racoon) and turn off wep. I just didn't want to change
anything until I know what is causing this problem...

 The fbsd box is also running:

 - routed -q
 - natd
 - ipfw
 - apache

 Many thanks in advance for all responses and advice.
