The Best Wi-Fi Adapter

Of the adapters we"ve tested, our pick is the TP-Link Archer T9UH. For the price, this AC1900 adapter strikes the best balance between cost and signal-boosting. The Netgear Nighthawk adapter is even more powerful, but costs more. The other adapters are cheaper, but didn"t improve the connection as significantly in testing.

I tested Wi-Fi 5 performance with a 500Mbps symmetrical Verizon Fios fiber connection using a Verizon Fios G1100, an AC1750 router. When I tested the Wi-Fi 5 adapters against each other earlier in 2021, my whole family was working & learning from home. Vị trí cao nhất speeds were unreliable because congestion kept changing. So, I focused on the signal strength & the speed loss when moving the laptop quickly from one location to another.

When I tested the D-Link Wi-Fi 6 adapter more recently, I could do so in a more controlled environment. As such, I was able to compare speeds between that adapter, the TP-Link Archer T9UH, and the TP-Link Archer T4U Plus. Those results are in the full D-Link DWA-X1850 review.

In terms of pure signal improvement, the more expensive adapters with better specs performed better. The below chart shows how each Wi-Fi 5 adapter affected pure 5GHz signal strength on my laptop, averaged over the four locations I tested it.

The Archer T9UH, an AC1900 dongle, had the best overall speed performance of any of the adapters I tested, making my home office wall seem nearly transparent lớn signal. The T9UH is 0.5 inch thick and 3.5 inches long when closed; it flips open to a height of about 6 inches. You can plug it directly into your máy tính or use an included USB 3.0 cradle. The dongle has a small xanh LED khổng lồ show it"s working.

And work it does. Over my 5GHz 802.11ac network, I saw an average signal improvement of 11dB at my four locations, as well as the lowest overall tốc độ loss. At one point, I was getting a higher speed in my office than right next khổng lồ the router, which was probably because of how other people in the house were using the internet. Still, this performance shows that the T9UH can really reach through the wall. The dongle didn"t bởi vì well with my router"s 2.4GHz network and refused to lớn connect to lớn that network from farther than a few feet away, but you shouldn"t be using a 2.4GHz network with an adapter lượt thích this. It"s really for boosting 5GHz signal & does that very impressively. The T9UH is our Editors" Choice winner out of the adapters we tested.
