How to Pick the Best Bluetooth Adapter for PC

Picking the best Bluetooth adapter is pretty easy. If you want to connect a certain device to your desktop or laptop but don’t have a Bluetooth adapter, pick a dongle that supports your device. Gaming controllers, for instance, are troublesome when it comes to Bluetooth connectivity. For maximum compatibility, check to see what devices are supported on the manufacturer’s page. For instance, Asus specifically states that their dongle is compatible with PS4 and Xbox One gaming controllers, so that means that you can connect said controllers to your Windows-based machine put of the box with no additional drivers.

That being said, there are other factors that can influence your decision. Let’s take a few minutes and go through them, as they all will affect one aspect of your experience.

Range

If you’re like me, popping some tunes turns a shower or a bath into an instant jamming session. Having a dongle that’s capable to go through a few concrete walls and closed doors means that your dongle needs a strong signal. With better range, your tunes will sound clearer and crisper even if you go to the bathroom.

Of course, this rule applies to different applications. Sure, if you have a wireless keyboard or mouse, range probably isn’t that important (unless you’re planning on pranking someone), but if you’re constantly on calls, then having good range means being able to keep your call quality crisp while you’re moving from room to room.

Price

There’s no reason you should pay too much money for a Bluetooth dongle. If you own a desktop and want to splurge some money, then go for a Bluetooth adapter (basically a board that you mount on one of the expansion slots). Bluetooth adapters work better, with more range and bandwidth for data transfers.

That being said, if you’re looking for a cheap alternative or just want something to use with a wireless speaker, then don’t spend a lot of money. Look at a few products, most of them are similarly priced, and pick the one that has the best connectivity and range for your needs.

Compatibility with Operating Systems

If you have Windows 10, then this shouldn’t be an issue for you, but if you’re running an older operating system or a version of Linux, then you need to make sure that your future dongle either supports your OS out of the box or has drivers that unlock it. In a nutshell, check the manufacturer’s page and go through their list of supported systems. Before installing the dongle, download the driver and run the setup.

How did you get the TP-Link to work plug and play? I wound up having to uninstall all the old bluetooth drivers to get it to work like that and even after doing that only audio worked. The Amazon page is full of comments by people with the same issue. I happen to have an old Toshiba Stack disc that allowed everything to work, like with my old adapter, but it’s for Windows 7, so I’m sure I’m missing some benefits of the new adapter.

Hi Adam. We are sorry to hear that you had problems with the TP-Link BT adapter. It should work plug n play and a lot of users comment that it does. Unfortunately, there are always some particular cases when the hardware and peripherals don’t work as intended. There isn’t much we can advise here other than just contact the manufacturer or return the product.
