Adaptar state not found in registry

I usually access internet by wireless in my laptop. Whenever I access the
net after a few minutes I loose the net access. Whenever I check the windows
firewall settings after I loose the connection it always displays that
windows firewall internet connection sharing is not workingOn looking through
the properties of the wireless network connection . when I try to configure
the wireless adapter it shows adaptar state not found in registry. I have
been told to use the device manager to uninstall the wireless adaptar and
reboot the system. I t has been working after I reboot but I have facing the
samre problem repeatedly. This way I have uninstalled and rebooted the system
many times, about 46 times. I would like to fix this problem permanently. Any
suggestion and solutiioons are very much appreciated.
