We're going to assume you want the easy way, but will explain how to go about doing it the hard way if you don't like the easy way. There are two ways you can upgrade a laptop's Wi-Fi: the easy way and the hard way. That's certainly true if your laptop doesn't support 5GHz Wi-Fi, and upgrading it can make a huge difference if you can be relatively close to the router. You might even be looking to upgrade so your laptop matches the Wi-Fi speed of your router or mesh system: the latest models can be significantly faster than older ones, and since most people keep their routers for a long time, that can can lead to quite a speed boost. Whether that's a flat refusal to 'see' any wireless networks or simply a very slow connection, it is a problem, that's surprisingly simple and inexpensive to solve. If you're having problems connecting to the internet, you might suspect the Wi-Fi in your laptop to be the cause.
