Thanks for the reply @geek2nurse , but part of the reason for posting on a public forum is so that the GF Community will have access to see the type of problems that are happening to others and [hopefully] someone who had the same problem can share some advice to get to a faster resolution.
To clarify, the Black Lid Cable was suggested to rectify the “constant scanning” problem that is now a known issue. The fact that my machine now takes 30 minutes to come online (each and every time…right at 30 minutes) was not clear to me when I opened my support ticket via email. And the response from support was “As for the offline issues, I see that your Glowforge was able to successfully connect to your network and our servers today. …” to which I responded with the additional information that became clear after the initial support ticket was opened.
It seems like there are many issues that GF support doesn’t want the community to have access to as in this recent example where you can find no public post of the resolution: Offline- Troubleshooting Day 2
