I installed GhostWall, it worked fine at first. After rebooting I got an error that the driver couldn't initialise. I figured that might be an odd instance, so I rebooted again, same problem kicked in. I uninstalled, and now after rebooting my WLAN LED doesn't go on anymore, and I can't scan for networks. It beats me why GhostWall would have done this, but, that's the order of events... Any ideas?
