After recently upgrading my acer laptop from the factory standard Vista to Windows 7 x86, for the first 4 weeks everything worked great (Wireless was working).
Recently discovered that the wireless capabilities have been turned off, and windows 7 would not let me turn them on. the troubleshooter says to switch the wireless switch ON 'can be found on the side of laptop' but this model does not have any such switch.
Have tried everything. from re-installing drivers, system restore to a complete system format and no success has been gained.
Please try the below mentioned steps and check if you are able to switch on the wireless capability on your laptop:
1. Press <Fn> + <F3> to bring up the Launch Manager window panel.
2. Locate the Wi-Fi toggle switch in this interface.
3. A red toggle indicates the device is off. Click the red toggle to turn it to green to switch the wireless device on.
