I have a Dell Inspiron 6400 and sometimes after I use it for prolonged times the wireless light will switch off and I will be disconnected from the internet. This has nothing to do with the router as other computers can work fine and mine does as well once I restart it. The issue is that it does this automatically when it shouldnt for any reason. It also doesn;t let me access the wireless network connections as it is frozen and nothing pops up. I can do this when I first boot up my computer or am not having this issue. Is there any fix for this? Please advise, thanks

Press those keys at the same time and you should see a pop up window and check if the current status is on. If it is on, uninstall/reinstall the wireless driver in device manager. and restart your computer. If this didn't work. You need to do re installation of your operating system.
