When I try to connect I get a message saying 'No connections are available'. There are connections, the other computer and my phone connect just fine.
I found something suggesting I reset the driver in Device Manager, but when I check there's nothing about wireless in there, I just get:
avast! Secureline TAP Adapter v3
Bluetooth Device (Personal Area Network)
Bluetooth Device (RFCOMM Protocol TDI)
LogMeIn Hamachi Virtual Ethernet Adapter
Realtek PCIe GBE Family Controller

So, what? Is my driver missing? How do I fix this?
