I just got a new Orbi router and am having trouble with connecting to my hub through it. It finds the Hubitat through findmyhub.hubitat.com, but when I click on it I get a "This site can't be reached" message. Is there something that I can do to make this work?
It appears your computer and hub are in different IP ranges. That makes it difficult to get them to talk.
I assume you have a gateway device from your internet provider in your network. It is setup to issue IP addresses to devices on your network. Your Orbi needs to be setup in AP Mode to ensure it doesn't conflict with this. Here is a picture of where to find this in the Orbi configuration.
As Wayne points out this is likely the root of your problem. It creates a situation known as double-NATting and has the potential to cause other issues as well. One note - when you flip your Orbi to AP mode anything that had previously been issued an IP address by the Orbi will get a new one issued by your gateway device. Some may require a bit of fiddling to trigger this process.
It took a day for it to take, but after holding the button for 7 secs and leaving it, the hub was found at 192.168.1.xx! Another afternoon later, I was able to get my philips hue hub talking to it (and everything else). Thank you guys SO much for your help!!
