ISP Change

Hi - I’m sure this question has come up many times, but I can’t find a step-by-step guide, which would be great. Basically, I have just moved ISP’s, to a fibre broadband provider, which has resulted in a new router. I have Home Assistant running on an Intel Nuc unit, and now obviously none of my smart home items work as connection has been lost between by HA instance and the NUC. Just wondering what I need to do, to update the NUC (which is currently displaying the command prompt) and the app please?

I just changed ssid and password on new router, to the settings of the old one. After that, everything just worked as normal.


The easiest way is to set your new router to have the same ip address space and wifi SSIDs as the old router then restart everything. No changes to HA.

This. I’ve changed hardware more often than I can keep track of but I always keep my IP network and wifi the same and never have problems.
