Problems with my wireless adapter. Help?

Every time I've gone to play minecraft multiplayer, my computer just shuts off and starts back up without warning after about 5-10 minutes. After rebooting, my computer says it has recovered from a serious error, and that wireless networking was the cause of the issue. My drivers seem to be up to date. my model is a Netgear WG311v3 802.11g PCI adapter. What should I do?
