I help out at a local school, where they provide wi-fi for students use on their own device.
One student purchased a new Acer e3-112 notebook and it cannot see the school wi-fi network.
It connects to wi-fi at home and can see my iPhone hot-spot. The school network is fixed to 802.11n and the network adapter is a Broadcom 802.11n Network Adapter.
The notebook runs Windows 8.1.
I've changed the driver from Broadcom to MS and also changed the user logon to local.
