First thing to do would be to go into the router and look at its device list, chances are they've just changed IP addresses. If you find them, assign each of them a Static IP address so they don't move again.
Go to your portal and you’ll be able to see what current IP is.
But, as recommended, you should reserve the IP address in your router (check your router manual as how this is accomplished is not at all standard). That way, the router will always assign the same IP address to your hub.
I found it and fixed it! Thanks for the help.
The HE before had a IP 192.168... and now it is a 10.120.... number, I tought an IP always was a 192 number. Can I change it back to the old number? Not that it is important
Thanks for the support, I have a feeling I'll be back
That sounds like you need to do a general setup with your router first before doing the intermediate stuff. The router is responsible (in the typical household) to handout network addresses. You need to tell the router what pool of addresses to give out. Most commonly it is the 192.168.1.xxx range but you can pick whatever you want. You'll need to go through your router's setup process then after you're all setup go back in and reserve network addresses for your devices. Personally, I have my entire network reserved so I know exactly what devices are connected and how to get to them but I'm a little anal that way.
There are several large ranges of non-routeable IP addresses that are used for Private networks. 192.168.0 and .1 are probably the most common subnets used by consumer devices, but the router may be configured to use any of those others by default. As @wecoyote5 suggested, you may need to do a first time setup on your router.
Selection of an unusual Private network space can be useful as a simple security "defense in depth" technique as it might confuse the really amateurish script kiddy! Ok, maybe not, but it sounded good...sort of like hiding your SSID....
