We've covered a lot of ground this week: why your WiFi slows down, where to put your router, why a guest network is worth setting up, and how to spot unauthorized devices. Today I want to leave you with one specific action item that most people skip, and that can quietly protect your home network with just a few minutes of effort.

Change your router's admin password.

What is the admin password?

Your router has two passwords. One is the WiFi password, which you enter on your phone or laptop to get on the internet. Most people know that one. The other is the admin password, which you use to log in to the router's settings page. This is what controls everything: your network name, your WiFi password, your guest network, your connected devices list, and more.

When your router was installed, it almost certainly came with a default admin password. Something like "admin," "password," or "1234." The brand and model of your router, and its default login credentials, are publicly available online. Anyone who can guess or look up your router's brand can potentially log in to your router's settings if you've never changed this.

This isn't just a theoretical risk. On a home network where you've had multiple people connect over the years, or anywhere that you've had guests, contractors, or neighbors access your WiFi, the admin password is the last line of defense for your entire network configuration.

How to change it

Log in to your router using the steps from Thursday's post. Once you're in, look for a section called "Administration," "Settings," or "Router Password." Create a new password, something you haven't used anywhere else, and save it. Write it down somewhere safe.

That's it. A few minutes of work and you've closed a door that most people leave wide open.

This week has been about understanding what's happening in your home network. Most of these things take care of themselves once you know where to look. But if any of this raised questions or you'd like someone to check that your setup is solid, that's exactly what PCRescue is here for. A remote session is quick, easy, and done from the comfort of your own home.
