nfs over wpa_supplicant random hangs

[Rett D. Walters]

Hello:

I am using wpa_supplicant 0.5.7 on both ipw2200 laptops and madwifi 
laptops with an Orinoco AP-4000 access point.   Every thing seems to 
work ok with a WPA-PSK setup except accessing an NFS server on the wired 
lan.  Sometimes NFS works, other times it just hangs when trying to 
access the server shares.  If I shut off WPA-PSK and remove 
wpa_supplicant, everything works fine.   The laptops are linux 2.6.18 
(gentoo 2006.1), and the server is 2.6.19 (gentoo 2006.1).  I am using 
NFS v3 over TCP. 

Is there any tuning on the nfs or wpa_supplicant that can be done to fix 
this?

Here is the client side supplicant config

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=users
#eapol_version=1
ap_scan=1
#fast_reauth=1

network={
ssid="RTWNetwork.com"
scan_ssid=1
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
psk="....."
priority=5
}

network={
ssid="RTWNetwork.comLR"
scan_ssid=1
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
psk="....."
priority=5
}

Thanks,

Rett Walters
