Copy this script and enter your Wifi credentials:

import network
station = network.WLAN(network.STA_IF)
station.active(True)
station.connect("YourWifiName", "EnterYourWifiPasswordHere")

Now you need to open a REPL to MicroPython via USB.

If your Wifi is within range of the board and the password is correct, your should see output like

>>> import network
>>> station = network.WLAN(network.STA_IF)
