Acer Aspire 1810T network switch


I got an Acer laptop which has a network switch at the bottom.
I usually turn it off, but turning it on does not work and it turns itself on sometimes after I turn the laptop off for a while.

How can I turn the network card on when I need it and leave it off when I don’t?

The driver is iwlagn and the card is WiFi Link 100 series.
