OctoPi on RaspPi 2B with USB Wifi adapter won't connect


#1

What is the problem?
I have a Raspberry Pi 2 Model B, which doesn't have built in Wifi. So I got a USB Wifi Adapter that is compatible with Raspbian per the Raspbian wiki. It can see the wifi networks around me using the iwlist scan command (there are too many around me and it prints the networks to the screen too fast to see), but won't connect to my own after editing the network supplicant file.

What did you already try to solve it?
ifconfig to see if the network adapter was working
Edited the wpa-supplicant file in nano on the RaspPi to confirm everything was correct

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)

OctoPrint 1.3.10
OctoPi 0.16.0

You'd have to make sure that your local zone is 2.4GHz rather than 5GHz. You might try using a local keyboard/mouse/monitor on the Pi so that you can run commands like ifconfig to see what's going on. If you get a RUNNING flag associated with your wifi adapter then that's usually a good sign that it's been issued an IP address by your router.
