How Can I Add Wifi to a Desktop PC?

You have a few options for connecting your desktop PC to your wireless network.

Not all desktop PCs come with built-in wifi, which makes total sense—why wouldn’t you just use an Ethernet connection for a system that’s going to mostly sit under (or on) your desk? It’s still good to have options, especially if your desktop PC happens to be located in an area that is difficult (or annoying) to access with a cable, and adding wifi to a system that doesn’t have it is easy.

You have a few options for connecting your desktop PC to your wireless network: you can use a USB wifi adapter, install a dedicated PCIe wifi card, or upgrade to a new motherboard with built-in wifi. (We suspect most people will go for the easiest options—numbers one and two.)

The convenient option: USB wifi adapters

A USB wifi adapter couldn’t be any simpler to use, assuming there aren’t any quirks with how your operating system recognizes or uses the device. Simply plug it into your desktop or laptop. You might have to install some drivers to get it up and running, but giving your system wireless capabilities should be an easy plug-and-play routine after that.

Since it’s a USB adapter, you can plug it into any working USB port on your system—on the front or rear of your system, and USB 2.0 or USB 3.0, too. (Though you might want to try USB 2.0 if you encounter any issues with a USB 3.0 port on an older desktop.)

The disadvantage of a USB wifi adapter is that you might find yourself bumped offline should your system go to sleep. You’ll want to play around with Window’s settings for sleep mode (sometimes, the answer might be a not-so-obvious choice ). You might even have to jump into your motherboard’s BIOS to make sure there aren’t any settings that are kicking off your USB devices when your system sleeps. You could also just disable sleep mode entirely, which isn’t the worst idea.

Additionally, USB wifi adapters can be hit and miss with their performance . Make sure whatever you buy is at least rated for speeds your router can support—don’t buy a cheap wireless-n adapter if you just purchased a brand-new AC1200 router, for example. And know that an adapter isn’t a guarantee; you might still have spotty connectivity wherever it is you’re trying to connect your system, or the adapter might not be as strong as it sounds on paper.

If you know your system is always going to need wifi access, you’re better off investing in a PCIe adapter with dedicated antennas. While these aren’t guaranteed to always beat USB adapters for performance in every situation, odds are good that you’ll encounter better speeds and lower latency (at least, compared to a tiny USB 2.0 adapter).

Best for connectivity: PCIe wifi adapters

PCIe wifi adapters offer the same kind of connectivity you’d find on motherboards with built-in wifi. They generally tend to work better than USB adapters—the tiny ones, at least—giving you more stable connections across longer distances (and better throughput). They’re also great if you know you’re going to need to use most of (or all) or your system’s USB connections. Offload your wireless adapter elsewhere so you have plenty of space for that flash drive, gaming mouse, or humping dog .

There are only three real downsides to PCIe wifi adapters, and they’re relatively minor. First, these devices can be a little more expensive than USB wifi adapters, depending on what capabilities you’re looking to get. Second, you’ll have to install them in your system. That shouldn’t be a problem for most people, but it can be daunting for newbies. Finally, depending on your motherboard’s configuration and how much other hardware you’ve stuffed inside your system, you might not have room for a dedicated PCIe wifi adapter. If so, it’s back to a USB adapter for you.

Best if you’re already upgrading your PC: A wifi-enabled motherboard

If you’re planning to upgrade your PC anyway, and you suspect you might need wireless connectivity at some point—even if it’s just to have a simple backup solution if your Ethernet connection ever gets wonky—consider shopping for a motherboard with wifi capabilities built in. Some might even come with external antennas that connect to the rear of your motherboard and allow you to position them wherever you want (like on your desk), rather than having them shoot directly out the back of your desktop PC. It’s a minor point, but one that might get you a slightly stronger signal (or work better for your desk setup).
