Look for a wireless icon similar to the attached picture on the keyboard, it locates usually among F1 to F12 keys, if you don't see anything similar from F1 to F12, then try looking from 1 to 9 keys. Once it's located, press and hold down the Fn key on the keyboard and press the key with the icon (i.e. wireless icon) simultaneously for a couple of seconds, this will turn on and off the wireless function of your system. Let me know if you need further help with the model number of your emachine. Good Luck.
Try looking in the program list for the program that starts the wireless. Click Start/Programs and look for the program that drives the wireless and open it.
Maybe you don't have your wireless turned on. Look on both sides and in front for the Wireless Switch and turn it on.
Also once the wireless switch is turned on there are keystrokes that can toggle the wireless on or off. Normally you would Press and Hold the FN function key located at the lower left of the keyboard, then hit the correct F1 thru F12 key that toggles the wireless. The correct F1 thru F12 key to hit will have the wireless signal icon )))) on it. Or it might have the icon of a tower with the wireless signal icon )))). Normally the screen will display Wireless On or Wireless Off when you toggle the wireless.
Look on both sides of the computer and in front of the computer for a switch that controls the wireless.
Once you turn it on your wireless should come back. Also once you have the switch turned on there is another way to toggle the wireless on and off by hitting a set of keystrokes. If you Press and Hold the FN function key at the lower left part of the keyboard, then hit the key that controls the wireless (F1 thru F12) you can toggle the wireless off and on. The correct F1 thru F12 key will have the wireless icon )))) signal on it or it might have a tower with a the wireless icon )))) signal. Once you Press and Hold the FN key, then hit the correct F1 thru F12 key to toggle the wireless a message will probably appear on your screen that says Wireless On or Wireless Off.

Please mention whether you are using Notebook or a Desktop Computer. If it is Notebook please let me know the make of the Notebook as there will be a driver for the Function Keys to work. If it is desktop computer try using another keyboard to confirm if the issue is related to hardware of the Keyboard. For both the Wireless Keyboard of the Desktop and Notebook Keyboard it is required to press the Fn Key and the Function Keys (F1 to F12) together in order work.
I just had exactly the same issue. I found the answer on the HP website, but to save you looking for it, here's what you do:
1) Go to the BIOS for your machine. You'll do this by interrupting the startup sequence. On my Presario CQ42, I had to press ESC while the machine was starting.
2) Once in the BIOS, use the right/left arrow keys to move to the System Configuration tab.
3) Use the up/down arrow keys to move to the Action Key setting (Enable/Disable) and change it from the current setting.
4) Save and exit the BIOS.
Once your laptop finishes the boot-up, the F1-F12 keys should function the way you were used to.
