If the Wifi is stuck, it sometimes helps to do these tips from the Troubleshooting section:
Try this first:
Restart all the devices.
Turn off the computer, phone, or tablet that you’re using.
Turn off your Glowforge.
Unplug your modem.
Unplug your Wi-Fi access point.
Wait one minute, then plug everything back in and turn them back on.
If that doesn’t do it, try the more labor intensive fixes:
Improve the signal path between your Glowforge and your Wi-Fi access point.
Wi-Fi signals need a clear path. Remove physical barriers, and move devices closer together:
Move your Wi-Fi access point up high and make sure it’s in an open space. Avoid locating your Wi-Fi access point on the ground, under a desk, in a cabinet, or in a corner where its signal can be blocked.
Relocate your Wi-Fi access point closer to your Glowforge.
Move your Glowforge closer to your Wi-Fi access point.
Install a Wi-Fi range extender closer to your Glowforge.
Run an ethernet cable and install a second Wi-Fi access point next to your Glowforge.
Reduce electronic and Wi-Fi interference.
If your unit is near other devices that use Wi-Fi or a large number of electronics, temporarily turn off other electronics and devices in the area.
See if any of those tips get you going.
