I think I messed up when trying to assign a static IP address to my HE C7. I had it working fine in a wifi setup, with wireless drivers and a wifi dongle. We had lost power momentarily earlier this week, and my hub's IP address got reset - so I thought I would assign a static IP address but that didn't work, and changed to DCHP and somehow messed up.
Back to right now, I see my hub is powered up, see a solid green light, my router config shows the IP address with name "hubitat" but the web browser just says the IP address is not reachable. I even tried navigating to 8081 port, still same issue. The "find my hub" shows that it has found my hub and shows an older IP address, but that has the same response.
When I try to "ping" the IP address that "find my hub" showed, I get a reply from a different IP address (first three numbers look the same but the last is different) although it says "destination host unreachable".
I can't seem to "reset" the hub unless I am in either the regular user interface or the diagnostics interface, neither of which I can get into. Is there anything I can do to get back into my hub?
Sorry for all the deleting posts, I was trying to reply and quote your message but that wasn't going my way.
@bobbyD Thank you for pointing that out, I was able to get back into the hub (details below), now I see what you mentioned in the settings that, "Static IP/DHCP configuration is for built in Ethernet port only. WiFi USB adapters always use DHCP." - so this is what most likely caused the issue in the first place, so I will stay away from the Static IP for now unless I decide to go back to Ethernet port.
After I posted I found an article where it mentioned that the hub has a hard reset button at the bottom that I didn't realize. After turning the hub off, holding that button down for 10 seconds, I tried reconnecting to power and LAN, but nothing really helped - the hub got green solid light, but wasn't able to connect to. So this time, I pressed the hard reset again while the hub is still powered and connected, this seemed to have done the trick - I was able to see my hub got discovered and got a new IP assigned, I logged into the hub using the existing security credentials and all the devices, rules and dashboard are still there!
Oh okay that is good to know, I think that is what I needed in this case. The post that mentioned this option said "it will reset the network back to DHCP" so I may have assumed it was a hard reset, but either way, it worked for my case so I am glad!
