Hi @Peterpop
Most people, when setting up a new router, just accept the wifi setup on the new router or at best change the SSID and password to suit themselves, However, if you go a bit further, you can get away without having to reset any devices. What you have to do is interrogate your old router (probably in LAN settings) for connected devices and you will get a list of all connected devices, their IP addresses and MAC Addresses. The MAC Address is the unique hardware identifier of the device. So in your new router you first change the IP address range to the same as your old router, change the SSID and password to the same as your old router and then somewhere in the menu (probably LAN settings) you can assign IP addresses to MAC Addresses, also known as reserving IP addresses. If you then enter these in the same as the old router, your devices will never know the router has changed, This will also save you needing to reinstall your printers on your computers.
