I have been having consistent stability issues with linux and I believe my wireless card is the problem. I have a d-link GWL-510 802.11g pci card. It has no driver for linux, so I am using ndiswrapper. To begin, this is what I run to get my card running:

ndiswrapper -l ( I do this to check if the driver is loaded)
modprobe ndiswrapper
iwconfig wlan0 essid home142 channel 8
dhclient wlan0

This allows me to connect to the internet and it all works ok for about 3 or 4 minutes, then my system freezes.

The last line before reboot in my syslog says:
Wireless event too big (373).

Any suggestions for why this would occur? I'm using the newest version of ndiswrapper and I am using Ubuntu.
