If you’re like most people, you probably have a Wi-Fi signal that’s not as strong as it could be. In this article, we’ll show you how to fix a weak Wi-Fi signal on your PC. First, make sure that your Wi-Fi network is up and running. If it isn’t, you can try resetting your router or changing the password. Next, check your computer’s Wi-Fi connection status. If it says “not connected,” then try reconnecting to the network and see if that fixes the problem. If not, then you may need to update your computer’s firmware or install a new Wi-Fi card. Finally, if all of these steps don’t work and you still have a weak Wi-Fi signal, then we recommend using an app like AirBnB to find a nearby hotel with better Wi-Fi conditions.
This Hack Won’t Solve Serious Wi-Fi Problems
Before we dig in, let’s get one thing out of the way. The Wi-Fi hack we’re about to share is a simple way to get better Wi-Fi reception for your computer.
It works for desktop PCs, and it can even work for some laptops, depending on how you get Wi-Fi on your laptop. But what it can’t do is make Wi-Fi out of nothing.
If the signal from your Wi-Fi router at the location of your computer is extremely weak or not even present, then that’s a bigger issue you need to address first.
We’d recommend using these tips to improve your Wi-Fi signal at the router and then, if necessary, move on to dealing with the signal strength where your computer is located. You might consider upgrading your router to get better coverage not just for your PC but everywhere in your home.
How to Get a Better Wi-Fi Signal at Your PC
For the purpose of this Wi-Fi-enhancing trick, we’re assuming that you have a setup similar to the Wi-Fi setup found in our tutorial on adding Wi-Fi to your PC.
Whether you added a Wi-Fi card to your PC, the motherboard came with a Wi-Fi card built-in (like the MSI motherboard I used in my Fall 2021 rebuild), or you’ve been using a Wi-Fi dongle on your PC or laptop, you can follow along.
There’s a simple way to get a better signal: use an extension cable to move the antenna or dongle where the signal is stronger.
Why is this so effective? It gets the antenna above the stuff blocking the signal. Let’s say your PC is sitting on your desk and your Wi-Fi router is a few rooms over.
The metal shielding in the computer itself can mess with the signal (which is why desktop PCs have external Wi-Fi antennas). The metal shielding in your computer monitor doesn’t help, either. Even your body absorbs some signal if you’re between the antenna and the router. Everything else between the antenna and the router also dampens the signal and, in our homes, the majority of all that “stuff” is about desk height.
So if your router is on a side table in the living room and your computer is on your desk across the house, there’s a whole lot of waist-height junk between the two antennas.
Simply unscrewing the antennas off the back of your PC, attaching extension cables, and then screwing the existing antenna into extension cables can help you get the antennas up and away from the radio-blocking stuff.
The connection points on Wi-Fi antennas are standardized and use a connection format called SMA (SubMiniature version A)—it looks a lot like a little miniature version of the coax cables you use for your cable box because that’s exactly what it is.
You can use a 3-foot extension to get it on top of the PC case or a little up the wall, or even a 10-foot extension to get it all the way to the ceiling.
You can even replace the existing antenna with this extension + base for a more convenient way to place the antenna high up on the top of your case or a nearby shelf.
If you’re using a USB Wi-Fi dongle, you can use the same trick. You can use your existing Wi-Fi dongle and pair it with a high-quality USB cable. They even make USB extensions specifically for optimal dongle-mounting—which isn’t a phrase you get to use every day—that position the dongle in a vertical orientation on a small stand.
Or, especially if your particular USB dongle is a bit old and out of date, you could opt to buy a new Wi-Fi USB dongle that includes the extension like the TP-Link Archer TX20U or the ASUS USB-AX56, both of which support Wi-FI 6.
However you approach the problem, though, the goal is to get the Wi-Fi antenna higher than your computer and better positioned to get a direct “line of sight” shot at your Wi-Fi router with minimal stuff blocking the signal.
