# I have no wireless network when I wake up my computer

If you have suspended your computer, you may find that your wireless internet connection doesn't work when you wake it up again. This happens when the wireless device's drivers don't fully support certain power saving features. Typically, the wireless connection fails to turn on properly when the computer is resumed.

If this happens, try switching your wireless off and then back on again:

1. Fare clic sull'icona a destra nella barra dei menù e selezionare Impostazioni di sistema.

2. Open Network and select the Wireless tab

3. Switch the wireless off and then on again

4. If the wireless still does not work, switch on Airplane Mode and then switch it off again

If this doesn't work, restarting your computer should make the wireless work again.
