Is your wifi 5g or 2.4g or is it dual band? If only 5g is available, you need to provide it a 2.4g access point.
Are you using two different devices? One mobile device that is in airplane mode so as not to use cellular data an can only connect to the Glowforge’s wifi adhoc network. If you are your mobile device is using your wifi network to connect to the internet, you really don’t have to be in airplane mode. Just connect in the settings wifi area and find the ad hoc network. Have a laptop or desktop computer handy that is connected to the internet and can log into the app.glowforge.com.
Once you are on Glowforge XXX (found in the settings place of your mobile device), then in your wireless device’s browser, app.glowforge.com/setup should be where you are. It will identify your own network. You are looking for your own wifi network SSID at this time, not Glowforge XXX.
CLick on your own home wifi network name.
Once you are able to put the password the Glowforge is connected and then it normally passes you off to your normal network, unless you are still in airplane mode and then I don’t know that it will bypass that setting and connect to your normal wifi.
At this point go to app.glowforge.com and log in on another computer connected to the internet. You should see the Glowforge there.
If you need to do this all again, shut off the Glowforge, Turn it back on. Press the white button for ten long seconds until it starts to teal.
