To isolate the issue, the only 2 devices that are connected to my router through an ethernet cable are my computer and my C7 hub. I see both devices from my router network map on the same LAN.
The light is solid green on the C7 hub.
I have turned off browser extensions and my VPN.
when I use find my hub on Chrome, the C7 hub is not discovered.
I have also tried searching using the MAC address and IP through advanced discovery, but the C7 is still not found.
I also tried doing a reset using the tiny button under the C7 for 10 seconds. The light turned red, then blue, then green again. The issue was not resolved.
Finally, I have placed a warranty claim due to this issue. The dropdown on this warranty claim did not have an applicable reason, so I selected "I can't create an account". But if there is a way to get it to work, that would be preferable. I'm within the 90 days from purchase.
Don't panic (yet), as this very set of things happened to my brand new C7 when I got it a year ago. Eventually, it worked as expected, and I'm only sorry to say it did so of its own volition and not (IIRC) from anything I specifically did or that anyone told me to do.
Just telling you this so you know you're not the first, and that the green light is a good sign so keep trying.
Welcome to our community. And thank you so much for detailing the steps you have taken so far. It helps enormously to move closer to resolution. Please send me a private message with your new hub's MAC address. Having a warranty case on file also helps expedite your case if a replacement is needed.
