FreeBSD(AP) to WinXP(client) connections dropping out?

Hey Ppl,

Having some issues with a FreeBSD(4.8REL) Gateway to a WindowsXP(PRO) Client. Im using 802.11b wireless D-Link 520 PCI Wireless card on GW/AP. Seems to work fine until larger downloads or transfers(samba) occurs. At this stage connection unavailable displays on WinXP client and echoed to terminal is:

On boot ifconfig shows:

channel 11 authmode OPEN powersavemode OFF powersavesleep 100

using following start-up script /usr/local/etc/rc.d/wireless.sh:
#!/bin/sh
ifconfig wi0 inet up ssid spollard media DS/11Mbps mediaopt hostap
ifconfig wi0 inet 192.168.0.1 netmask 255.0.0.0
wicontrol -f 11
wicontrol -s "SpollardAP"

Once dropped ifconfig shows :
wi0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::205:5dff:fe5b:c6f6%wi0 prefixlen 64 scopeid 0x3

anyone else had this problem or could point me in direction for repair?

From google, I'm assuming from the wrieless lists on FreeBSD.org:

Take a look there, maybe it'll help jumpstart your search.
