Please add a menu entry where one can select a wifi network.
I have installed 12.0-RELEASE on my Macbook 5,2 and was asked if I would like to get a DHCP address while in installer mode. But I was never asked to what wifi network it should connect.
Works for me. See "2.8.2. Configuring Network Interfaces"
(In reply to Vladimir Botka from comment #1)
The handbook says:
"If a wireless network interface is chosen, the system will instead scan for wireless access points"
This is not true, so I had opened this bug report.
SHALL: installer should scan for wifi access points or installer should ask me for the wifi ssid
IS: installer asks if I want to configure IPv4 on my wifi interface
This appears to be a problem with the documentation.
