Before you go out and buy a USB

Wi-Fi adapter, we highly recommend that you check out our quick guide below:


One of the first specifications that you’ll see when shopping for USB WiFi adapters is the 802.11 standard.This refers to the ability of the adapter to communicate with routers. Afterthe 802.11 designation, it’s usually followed by a g or n. So you’ll see labelslike 802.11g or 802.11n.

However, these are old standards. The latest one is the 802.11acwhich has a theoretical speed of 720 Mbps. One thing you need to know aboutthese standards is that they are backward compatible. So if an adapter iscompatible with 802.11ac but the router only supports 802.11g, the adapter willstill connect to the router but with slower speeds.

If you can, go for WiFiadapters that support the latest standards for a more future-proof purchase.


Modern routers nowadays utilize radio signals based on either the 2.4 GHz or 5.0 GHz frequencies. While these frequencies are usually plastered on the packaging of most wireless devices, there are still many folks who don’t understand their meaning.

Basically, 5 GHz frequencies are faster than 2.4 GHz frequencies. However, some routers (especially older ones) do not support 5 GHz frequencies. While 5 GHz bands are faster, 2.4 GHz frequencies have better range since they travel further than 5.0 GHz ones.

So which frequency is better?

It really depends on the user’s needs. In most cases, 5.0 frequencies tend to have lesser interference from other devices and offer higher connection speeds. Overall, it’s better in terms of connection performance. However, if you need better range, 2.4 GHz is theway to go.


Before buying a USB Wi-Fi adapter, it’s always a good idea to check if your computer’s operating system is supported. Otherwise, what’s the point?

Fortunately, most adapters nowadays will operate on the latest operating systems for Mac and Windows machines. Some adapters will even support Linux. If you are on Windows, there’s a good chance that your system will be supported unless you are using a very old version like Windows ME or something.

The best way to verify is tocheck the specs of the adapter before buying.


That wraps up our list of the best USB WiFi adapters that you can buy on the market. At first, it might be a little overwhelming to shop for an adapter, especially considering the number of brands and models out there.

However, if you have read this guide, you should have enough information to make an informed choice. In my opinion, it’s hard to go wrong with any of the devices that I have listed above but it’s always best to do your due diligence.

Hopefully, this guide has helped you buy an adapter that’s right for your wireless needs.
