Hello, i have an emachines m6811 and periodically when i restart it the antenna will be off. When I click on it and click enable, I get an error message that i have to turn it on with the harware control switch... I have no idea where this is..I know its a matter of using the keyboard but i cant remember what. can anyone help? Thanks

You could have just gone to your support website and downloaded the manual.
Here's the link for your laptop manual anyway.

also woody he may have to go in his BIOS and setup the wifi features there too so that way he won't have to keep turning the switch on and off manually
