I've just tested on a RPi3 A+ on 9.2.0 and all works as expected. So it's possibly not an LE issue? Try installing Raspbian and see if the wifi works there (If not, it's possibly a H/W issue)
Can you try 9.2.1 and set the Wifi on the startup screen and see if that works. (make sure you choose the RPi2/RPi3 image.
Yes, the log files will be readable on any Linux based system.
NOTE: Check that your RPi A+ looks exactly like the image. It doesn't seem to have a wifi chip. So it's probably a RPi 1 A+ which doesn't have wifi.
This is an RPi3 A+
