It kinda sounds like WiFi issues to me. If I were you I would follow the advice given by Glowforge staff in a recent similar posting (I’ve pasted it below). If that doesn’t help, you might want to post your issue in Problems & Support.
I’m so sorry for the trouble.
The most common solution to Wi-Fi challenges is to restart all the devices involved in connecting to the internet.
- 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 work, we have two more suggestions that often make a big difference:
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.
I hope this helps. Please let us know if you’re still having trouble.
