Just flashed a microSD card for my new Pi 3B+. I left the Pi untouched and plugged in via ethernet for a couple of hours before I messed with it, per the instructions in the txt file.
Everything appears to be working fine except wifi. I hit the Network tab, Interfaces, added wlan0, entered in my SSID and password, set method to DHCP, Saved, Applied, and wifi doesn't work. What am I missing?
System dashboard reports kernel 4.14.30-v7+
I'm aware that performance might not be great over wifi (and it's a Pi) but I want to see for myself.
