The dell computer says use the function key to turn wireless on so I can connect to wireless. However, it does not specify which function keys Fn and f7 or f8 or ???. How do I do this?
It depends on the Dell. On my (pretty old) Dell, it is fn-F2, it could be also fn-F8.
If you have installed all dell Utilities, pressing Win-X will let you enable/disable wireless from there.
