Quick question: How’s your Wi-Fi on your computer? A lot of people might find that older machines just don’t get the speeds they could. A lot of that might be due to internal hardware that just isn’t compatible with modern Wi-Fi networks. Rather than shop for a new computer, try the TP-Link AC600 USB Wi-Fi Adapter. This gadget is a plug-and-play miracle that supports speeds up to 433Mbps and works with both Windows and Apple computers. You can score one right now for just $17.

Why is this a good deal?

Wi-Fi adapters vary wildly in price. This one brings not only great value and ease of use, but it also works with the latest operating systems. It’s also significantly cheaper than most comparable options, some of which can be $50 or more.

Why do I need this?

If your computer doesn’t have Wi-Fi connectivity or it just doesn’t perform like it used to, this adapter can breathe new life into it. All you have to do is plug it into the USB-A port on a desktop or laptop and it will be good to go; in fact, most users report that it automatically downloads any necessary software and will work after just a few minutes of being plugged in.

Also consider that it gives up to 200Mbps for 2.4GHz Wi-Fi, and up to 433Mbps for 5GHz Wi-Fi. Since it can connect to both, you have redundant connectivity. If the network lags, you won’t lose Wi-Fi right away. TP-Link also claims that the AC600 has a high-gain antenna which enhances the strength of Wi-Fi signals.

So how does it work? The simplest explanation is that this is an antenna that intercepts Wi-Fi signals and transmits them through the USB connection. If your computer just isn’t picking up internet (whether it’s because of geographic reasons or because the hardware is older), this adapter can be an inexpensive fix. These speeds are more than enough for you to stream your favorite shows or have a late-night gaming session. Don’t settle for slow network speeds when a $17 solution is just a few clicks away.

What reviewers say

“An amazing difference in speed,” one user reported. “9Mbps to 98Mbps on a 100Mbps plan.” For those keeping score, that’s an almost 1,100% increase in speed. “My internet connection speed went from 4mbps to 34mbps. No joke,” shared another fan.

Even shoppers in rural areas reported major benefits. “I’ve had multiple Wi-Fi adapters but because of my location (I live in TN which consists of mostly woods and valleys) it was difficult for some reason for the others to pick up Wi-Fi. This one is the first one I’ve had absolutely no trouble with, even at set up!”

“One small downside is that the adapter does stick out a bit from the USB port, which may be a concern for those who prefer a more streamlined setup. But personally, I don’t find it to be a major issue,” another customer wrote.

It might not look like much, but this antenna can majorly boost your Wi-Fi speeds.
