TP-Link AC1900 High Gain Wireless Dual Band USB Adapter for PC, Desktop, Laptop and Tablet (Supports Windows XP/7/8/8.1/10/11, OS X (10.9–10.13), Beamforming Technology, WPS Button) (Archer T9UH)

There no issue faced.

I was struggling with low download/upload speeds, unstable latency and low coverage signals but the Archer T9UH fixed all that in an instant! Now I am able to connect to my 5GHz with full coverage signals thus having achieving high internet speeds. But the best part about the T9UH is the latency, compared to its competitors the T9UH is known to have a stable low latency at all internet speeds. In my usage I have not had any sudden internet speed drops if there will be its little to none.For the customers complaining about this product, I suggest installing the default windows driver for the T9UH (meaning its basically plug-n-play). Don't install the TP-LINK driver as you will get lower internet speed results. From my experience compared to AC1900s of Netgear and Asus, the T9UH overall is the best pick.

Does not work as well as T4UH. When you plug it into a Laptop and installing the necessary software, The blue light on steady does not blink like the other adaptors I have.

Having spent several years struggling with wifi signal in a spare bedroom which was converted to an office, I bought a TP LInk RE365 plug in booster. It improved things a little, but still slow to connect and constant drop outs. Even worse, my mobile phone woudl stay connected to the RE365 when I was in the lounge near the router, so my phone was very slow unless I disconnected and reconnected it. In desperation I bought this AC1900, really expecting no better. Absoltuely wonderful, almost instant connection, no drop outs and good signal & wifi speeds. It sits on the desk but is very neat, in fact my wife knows I have it but still hasn't noticed it. Phone stays connected to the router. Highly recommended.

Wird benötigt, um meinen PC mit dem W-Lan hinter einer dicken Wand zu erreichen. Das klappt ganz gut. Er wird aber wirklich etwas heiß im Betrieb.

I recently upgraded from 30Mb Fiber To The Cabinet (FTTC) to 500Mb Fiber To The Property (FTTP). Using my laptop to connect via WiFi to the router whilst standing next to it, I measured 500Mb/s download using fast.com, which speedtest.net corroborated.Upstairs on my desktop, however, I was using the TP-Link TL-PA4010KIT powerline to connect via ethernet. Having used that setup for over a year, I can say the connection was not stable and, as seen in one of my attached images, there was a massive loss in speed (27Mb/s on a 500Mb FTTP full fiber connection - madness). Upgrading to the T9UH, however, I saw an immediate improvement of 480Mb/s to even 520Mb/s using the abovementioned speed tests. It's worth mentioning that my house is a average-sized terrace house built in the 80's; my router is on the ground floor at the front of the property and my desktop is upstairs at the back of the house - the signal is traveling upstairs and through a wall or two.I'm very happy. Even if I get 480Mb/s, that's still within the margin of error for my contract, a massive improvement over my old 30Mb/s FTTC connection, and impressive performance given the obstructions between my router and this tiny USB adapter.

That's a great product, I'm working from home receiving the stream of the screen of my pc in my office which requires a strong and most importantly stable connection (that doesn't drop the power randomly during the day). I was using my laptop receiver with very bad results (15-20Mb in download, dropping the signal quite often during the day), the router is one floor downstairs. With this receiver it is now incredibly stable at 110Mb in download, which is exactly the max limit of my broadband contract and it never drops (meaning that there's no loss at all even though there's one floor between the router and the receiver).Fairly easy to install, and it happened once for now that it stopped working, but unplugging and plugging it again solved the problem.Definitely recommended!
