I accidentally, via the admin page, set my C8 hub to connect via WiFi. I can no longer access the hub. It has been connected via Ethernet cable using a reserved IP address and has worked fine.
This is what I've tried to fix the problem.
Removed the reservation from the router.
Disconnected the Ethernet cable
Rebooted the router
Pressed the button on the bottom of the C8 for 10 seconds
Used Find Hubs from my PC, which is on the same network as the hub (Ethernet cable).
Entered the MAC Address of the C8 on advanced search and when searched, the result was the hub was found via the reserved IP address. I thought this would be deleted via the button press on the bottom of the hub. (I cannot remember if I set the reserved address in the hub).
I HAVE NOT unplugged the hub in fear of corrupting the database.
A network reset, which it sounds like you tried, should work, but maybe it didn't actually reset: did you see the LED change colors after you held the button? I believe it's supposed to blink, but you should definitely see it turn blue and (eventually) back to green as the hub reboots, just as you would if rebooting from any other method. If you don't, try holding for closer to 7 seconds and see if that changes anything.
When I press the reset button, nothing changes with the LED. I stays green and doesn't blink. I also tried the 7 second press and that didn't make a difference either. Thanks for responding.
In that case, the network reset is definitely not working. Consider playing with the timing a bit more or using this as the one excuse you can use to pull power and see if anything changes (including the ability to reset if you still can't reach the hub) after it comes back up.
I'd also see if you can reach the Diagnostic Tool at any of these IP addresses. You can use that tool to reboot the hub as well, among other troubleshooting that may get you back into the regular interface.
I tried your suggestion of timing the button press, and it behaved the same way. So I pulled the power and plugged it back in after close to 10 minutes. Ran Find Hubs via the MAC address and it returns the reserved reservation. I pressed the button on the bottom of the hub and waited 7 seconds and this time the LED acted as you described.
I ran Find Hub and entered the MAC address and this time I noticed the connect to Hub button could be pressed so I tried it. It Connects!!!! I looked quickly at the logs and other parts of the system and it look ok so far.
I can't thank you enough for your help. Just one more question... How will I know if I corrupted the database? Thanks again
The hub will notify you if it knows (possible if it's really bad), or if you notice odd problems like apps not working as you expect (when the devices they control are still functional), you may have clues about smaller problems. A reboot using the "advanced options" sections to automatically perform soft reset as part of the reboot is an easy way to recover from that; for anything major, which it sounds like you're past, you'll need to restore a known-good database. It's a good idea to download these from time to time (or have Hub Protect to store them in the cloud for you), but the hub also stores the last several for you -- created according to your schedule in Settings -- and one of those should also work.
Despite all the warnings you'll, this is still pretty rare (but so easy to prevent that your caution is warranted), so I wouldn't worry about once when everything appears to be working fine afterwards. Glad you're up!
