TP-Link AC1900 USB 3.0 WiFi Adapter (Archer T9UH)

I bought this particular wi-fi adapter for a desktop computer that needed something ten times better. The unit that was included with the PC was a simple finger tip sized USB dongle that only had a weak signal and poor quality. That said, I installed the TP-link to combat this issue. This adapter can either plug directly into a USB3.0 port, or plugged into a cradle that gives the unit more room to stand straight up. This in turn offered the best signal. There are two dual band routers installed in the home, and even the main router had about three bars although it was all the way on the second floor. The router that I use I had installed myself close to my area, but if I hadn’t, this little gem still would have performed well. This unit is amazing, and is easy to unpack and install even for a totally blind person like myself. Just decide how you wish your device to be placed, either straight up on a desk or plugged into the computer’s USB port, then plug it in and get back in business.
I’ve had no problems with the device so far. It works extremely well and allows me to perform activities even when out on the swing. It also works well for online gaming, and work or school. Lastly, the price tag was no issue. I would absolutely recommend this for someone who needs a great wi-fi adapter to be installed externally.

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.

I’ve used a few USB dongles on my laptop to try and get wifi at work, and all of them seem to be “ok”, but really I lose the signal maybe once an hour, and none of them were really satisfactory. I saw a review in a PC magazine about the TP-Link AC1900 USB WiFi Adapter, so bought it assuming it wouldn’t hurt to try something new.
Good Lawd, I can now connect to two hotels next to my work, and even a hotel on the other side of the river my work is near, I googled it and the hotel is 1200′ away. There are weird wifi signals that I can only assume to be residential. Absolutely mind-blown, I have to share how creepy-amazing this device is. Unbelievable. Perfect wifi at work for two days now. And if work wifi doesn’t function, I can always choose a few hotels wifi to use; so far one of their PWs are “guest” and another has no PW.
Beyond pleasantly surprised. I regret not getting something like this sooner. The price is oddly low as well.
Oh yea, it’s plug-and-play. Didn’t need any drivers, even though it came with a CD, which worried me at first.

As I said, I have been using the product for almost 2 years, so more than 1 year…
I bought it because it is a popular brand and expensive. Of course, the reasons why it was expensive were that it had better quality or more features…
When I bought the product, I was having problems with the internet cable. Wi-Fi was pretty good but I was having problems with the cable. I do internet work all the time, so internet is very important to me. I immediately ordered one of this product. Unfortunately, when I bought the product, I could not use it at all. Waited months…
I have now moved to a new house 2 bedrooms 1 living room a normal width house. I installed this wireless plug-in on my computer. The modem is in the other room. There is only 1 wall between us, the doors are open and the distance is about 4-5 meters. But I am having signal problem.
According to the statement:
-LIGHTNING FAST WIFI – AC1900 (600Mpbs on 2.4GHz band or 1300Mbps on 5GHz band) wireless speed with the next generation Wi-Fi – 802.11ac
-USB WIFI ADAPTER – 2.4GHz and 5GHz band for flexible connectivity
-ULTIMATE RANGE – High gain antennas ensure superior range and stability
-BEAMFORMING TECHNOLOGY – Delivers a more targeted and highly efficient wireless connections

But a device with these features should give better results. While it should be able to detect Wi-Fi from 50-100 meters in the mentioned features, I am at a distance of 5 meters and I get 3 bars of service. I recently bought another device that pulls 5 sticks and makes me happy. I don’t know why, but I think the device has a problem.

Although there are 3 bars, the speed ratio is quite good, but not sufficient. Because I’m constantly uploading and downloading. What I need right now is to have 5 sticks and to be able to use my internet fully.
