Do you just plug in a new router?

Written by Editorial Team | Last Updated: August 2026

Replacing an existing home router with a new unit is generally a straightforward process that involves unplugging the old device, connecting the new router's WAN port to your modem or ONT using an Ethernet cable, and powering it on. However, successfully establishing internet access may require running a quick initial setup wizard via a mobile application or web browser to configure administrative passwords, update firmware, and establish your personalized Wi-Fi network name and security credentials. If your internet service provider uses MAC address authentication or specialized VLAN tagging, additional configuration steps might be necessary.
