When your internet was set up, the router most likely came with a default admin password, often something printed on a sticker on the bottom. Plenty of homes never change it. That is worth fixing, and it takes five minutes.
There are actually two passwords on a router. One is the Wi-Fi password you type into your phone and laptop. The other is the admin password that logs into the router's settings. It is the admin one people forget about, and it is the one that matters most.
Default admin passwords for common router models are listed all over the internet. Anyone who gets onto your network, or in some cases from outside it, can log in, change your settings, redirect your traffic, or lock you out. A strong, unique admin password shuts that door.
It is also a good moment to make sure your Wi-Fi uses WPA2 or WPA3 security, to rename the network if it still shows the brand of the router, and to update the router's firmware. Those few changes make a real difference to how safe your home network is.
If logging into a router is not your idea of a good afternoon, we can sort it and check the rest of your network at the same time. See our wireless network setup service.
