~~~ theres a power saving option on the wireless adapter that is turned to maximum by default. To turn it off, right click my computer > properties > hardware tab > device manager then find your wireless adapter in the list under Network Adapters, right click > properties > advanced tab. Select Power Save Mode from the list on the left and select Off from the drop down on the right. Press OK and close device manager.
I have an acer laptop at work & the wireless switch slides across to the right & then springs back & slides across again to switch off - confused me at first too - but actually mine wasn't working at first, so I had a complicated conversation with the tech guy on the phone with me saying 'the switch won't stay on' meaning the wireless wasn't working & him saying 'it's not meant to', thinking I meant the switch didn't stay to the right. Glad yours is sorted.
