I recently received my Pi Zero W and had problems trying to connect to wifi. When i installed RetroPie and went to WIFI to connect, no wifi SSID was listed. I used another SD card to write another image and it was the exact same problem.
I then used a friends Pi Zero W with both images and they listed the wifi SSIDs and connected fine.
I then check the firmware on both Pi Zeros and my one displayed Pi Model B+ and my friends had Pi Zero W V1.1
Is this something that can be fixed by updating the firmware?
