>Description:
wpa_supplicant(8) isn't working reliably.  using a simple wpa_supplicant.conf
against Linksys AP and stressing the network results in dropped connections
after minutes (or seconds, when using specific traffic).

my /etc/wpa_supplicant.conf:

 network={
         ssid="klozet"
         bssid=00:12:17:dd:27:6e
         scan_ssid=1
         key_mgmt=WPA-PSK
         psk="testing key"
 }

running wpa_supplicant:

so far so good, network seems to work just fine:

now i try to open few bookmarks at once in tabs in firefox, tunnelled via ssh

and the newtork link drops.  to bring it up again it's necessary to kill
wpa_supplicant(8), bring the interace down and up (several times) and start it
again.
>How-To-Repeat:
set up a basic WPA configuration,
start wpa_supplicant(8),
generate multiple http requests at once over tunnelled connection,
see network go down

 also one interesting datapoint, when this happens another WPA client on
 the network, a Windows XP machine, gets disconnected from the network as
 well.  i can't tell whether this happens because the firmware of the AP
 is buggy and what i see on the NetBSD client is just a result of it or
 whether it is caused by the NetBSD client.  unfortunatelly, i can't test
 against a different AP now.   there are newer firmwares available for
 the router (WRT54G v2.2), the current one running is v3.03.1 and v4.00.7
 mentions: "Resolves issue with enabling TKIP after enabling WEP" which
 is rather vague and can apply to my situation.  the AP is not
 technically mine but i'll try to upgrade it tomorrow and report back.

 regards,
