GREAT After I Realized a Windows SETTING was stopping it from working. EVERYONE TRY What I did!
Color: black
RE: TP-Link AC1900 USB 3.0 WiFi Adapter for PC (Archer T9UH)- Dual Band Wireless Network Dongle Like a lot of other people I thought this thing didn't work & was about to send it back. Looked up all kinds of reviews for other ones like this and over & over saw the same theme, dropped connections or slow speed. We'd gotten a new Dell PC so our oldish one went to a back office and we got this to amp up it's (outdated) wifi capabilities. No matter what we tried it would only work verrrrrryyyyyy slowly. The other day I started messing around looking at wifi settings and had almost given up when I stumbled across the page that changed everything. Keep in my this is Windows 10 I am talking about so if you have something different, figure it out from what I did: >> NETWORK CONNECTIONS >>ADVANCED NETWORK SETTINGS and then, there it was: >>CHANGE ADAPTER OPTIONS what I saw before me were 5 things (2 of which matter here), and only one (the PC) WAS connected to wifi. What's the problem then? One of the OTHER things that showed up was: "Wifi TP Link Wireless USB Adapter" <~~ NOT connected to the wifi I right clicked to connect it and you could almost hear it peel out. I immediately did a speedtest and laughed my head off when it was blazing fast. And it stayed that way. ***UPDATE: A couple weeks later the same happened, I repeated above and saw it needed to be RE-Connected so that fixed it again. While this is a great product, having to do that, despite having "Automatically connect" checked off, reduces it a star, but looking at other brands reviews I still feel I picked the best of all the options. At least this has a quick easy fix by searching Windows for NETWORK CONNECTIONS and doing above*** So all that time the slowness was just the old computer (normally fast when hooked up directly to the internet) trying to chug along and suddenly become a wifi PC with it's wifi tech from 15 years ago...it wasn't the adapter at all, because the adapter, though it showed all the signs of being hooked up properly, wasn't REALLY doing anything due to that one setting deep inside Windows that no one indicated was a thing when using this. And I found it. ME. The unlikeliest of tech gurus on the planet. Try it! It seems like we have two new Dell PCs now with this upgrade. You're welcome! :) ... show more

Actually reliable and fast speed, quick driver install
Color: black
My goodness. This is a savior. Summary: Getting the full 250Mbps on a 250Mbps isp subscription, when I was previously getting 70Mbps with my internal wifi card. Stable connection, no increase in ping/latency. I'm used to having direct ethernet fios gigabit connection. So when I moved to a suburban home with old walls etc, I was mortified to see that my laptop's internal WIFI chip was only pulling 70Mbps. I thought about switching out my WIFI chip, but seemed a bit like a hassle, and hard to factor in which dbi to use (stronger more reliable vs distance), walls and interference etc. And this adapter was a simple setup, with one driver download and install (without restart. It integrates the wifi control into your Windows 10 default wifi icon, so you can easily switch between Wifi1 (internal wifi card) and Wifi2 (TP-Link adapter). This worked like a charm! Things to consider before purchasing this adapter though: ~Make sure that the bottle neck of your slow internet connection is caused by your wifi card, not other factors. ~You can test this by connecting a direct ethernet cable from the router to your laptop and testing the speed, AND testing via wifi connection with your laptop right next to the router itself. It should match to the full speed provided by your ISP. If not, the router could be the problem. ~There's an app that scans the wifi channel signals in your vicinity, to make sure it's not conflicting. Go into your router settings and change to a channel that is unoccupied to eliminate interference. This device supports USB 3.0, and I have no doubt that the 5Ghz bandwidth is capable of the full 1300Mbps that it advertises. In which case, the bottle neck would be an ISP's Gigabit connection, if you have one. Otherwise, I don't really see the point in insisting on using it on a USB 3.0 port if you don't have one. USB 2.0 technically supports up to 480Mbps, which is more than what most suburban ISP packages offer. ... show more

Archer T9UH / So far very good
Color: black
So just received this last night and set it up with no issues. Downloaded the latest driver from other PC, more on that later, and installed on the workstation using the TP-Link device. It instantly recognized the adapter and installed. I noted continual USB disconnect and reconnect audio notifications, but after a computer restart and a reset of the USB adapter onto the platform, those stopped. Unfortunately the driver is more than 3 years old. I checked on this prior to purchasing but given the generally good reviews I decided to to try it anyway. Thankfully, reception and speeds are good. We're getting wired speeds of 600 Mpbs. After optimization and restart of our ATT Arris BGW210-700 that is AC speeds capable. I'm getting 450+ Mpbs down and 380+ Mbps up. That's at a distance of around 25-30 feet and through 2-3 sheetrock walls, the router placed low in the livingroom and adapter placed reasonably high on the other side of the house. I would recommend this product, but then longevity is still in question as I've only been using it for 12-15 hours at this time.. ... show more

Worked for 6 months; NIC's with Realtek chips are a common problem
Color: black
Worked for 5 or 6 months. Very fast connectivity, 5G sixty feet, and one story away (2400 sq ft, two story house). Typical router to NIC connection was at 800 MBPS. I upgraded the router to a TP-LINK AX11000 two months ago, because of gradual degradation in the signal to my laptop. Now the 5G NIC connection tops out at 390 MBPS, and quickly degrades to 130 MBPS, to the point where it can't hold a lag free signal gaming, and streaming flickers. I've tried 4 or 5 replacement USB NIC's over the past two years, and all are problematic. From the research I've done, Realtek has been pumping out some bad chips, and most NICs of this class (AC1900, similar) have Realtek chips. When it works, it's extremely fast. I get about 475 MBPS direct from the cable modem, and was able to get up to 300 MBPS to my laptop using this NIC. Then both signal stability suffered (i.e. jitter, you can see it on speedtest "latency", jumping from 26, 75, 50, 500, 750, 250, etc, ending up total latency > 100), and speed (200 mbps, then 100, then below 100. Reboot the PC, and/or this NIC (disable/enable), it pops right back up, then starts degrading. Sometimes it last for an hour or two, sometimes 15 minutes. If I tried to run this in for a warranty claim, TP-link would claim it's my router, my network configuration, my laptop, and I'd be off and running for 25 hours of directed debugging. I was in the IT business 35+ years (network, databases, software development, etc.), I've done the testing, and I know this NIC is fried. I'm just giving up. I've got conduit in my home, and I'm biting the bullet, running CAT6 hardware throughout, to end the endless wireless issues. This is my second TP-link router, and first NIC, and I won't be buying TP-LINK products anymore. Just be aware, avoid Realtek-chip based network equipment, if at all possible. ... show more

I don't leave reviews often
Color: black
TLDR: went from 30 mbps to over 300 mbps with this product This thing blew my mind. So based on a suggestion from reddit, I purchased this wifi adapter due to PCIe wifi card being nearly 10 years old in my gaming pc. I usually have a wired connection so i just removed my wifi card all together, but due to interference, the modem and router needed to be moved to the bedroom about 30 feet away. I put my old wifi card back in (removing a few quality of life aspects in my pc) and tested my speeds, only getting 30 mbps or less. I decided to bite the bullet and try this to save space for my quality of life additions I had made and was not disappointed. I am now getting nearly 400 mbps speeds. I first installed this without the suggested drivers based on a previous review, but I still was only getting 30 mbps or less. After the driver update I started getting 300 to 400 mbps consistently. I'm not too sure how well it works with longer distances, but this fits my needs perfectly. Also, installation was a breeze. For me it was simply plug and play, even without the drivers. ... show more

Started with 5 star, changed to 1, now up to 3
Color: black
5 Star. This is replacing a simple plugin wireless N adapter. We were unable to stream 4K movies on the home network so we figured we'd give this a try. Installation was simple. You either plug it directly into a port on your computer or use the cradle to sit it in and run a cable from the port to the cradle. Since this particular computer only had 3.0 plugs on the front and not the back we opted to use the cradle rather than have this sticking out in the front of the computer. It looks nice sitting in the cradle plus this gave it more height over being plugged into the computer which was on the floor so there's no problems there. The included disc didn't work at all with 10x64. It just kept throwing out errors. Going online and downloading the proper drivers was easy enough and those installed without any trouble. It connected to the network with no issues. One thing I don't understand fully is how it chooses the wireless type it uses. For example, when first installed, just a mere 4 hours ago from right now, it stayed on the 2.4 GHz band for about an hour then when I came back and looked again it was then on the 5 GHz band. It says on the box that you can choose between the two bands but it doesn't say how and there's no instructions. So I hope it stays on the 5 GHz band because I don't know how to change it if it doesn't. Also, there's no instructions on how to change the channel that's being used. Of course, this only applies to people who don't already know how to do things like this but there's plenty of them. Including me when I'm trying to install this on Windows 10 on a friends computer. I don't know where anything is on Windows 10 so basic instructions would have been helpful. One more thing is the antenna. It doesn't state how you should place the adapter for optimal coverage in the direction that you want. I know it's omni-directional so it probably doesn't matter that much. It just seems that one way would always be even slightly better than another. But, all of that aside, I then tried to stream 4k movies to 2 different locations in the house that didn't work before. They both streamed with no buffering! So, as of now, this device seems to have fixed my problem. I would recommend this device to others. If anything changes I will come back and edit this review. EDIT 1 Star: This product only worked for about 10 days before the speeds just died. The first 10 days it did great. I could stream anything I wanted with zero buffering problems, which is why I got this device to upgrade from the Wireless N adapter built into the computer. For some reason, I still don't know why, after about 10 days it just went to garbage. I can't stream 4k, Bluray or even DVD quality - and this is on the 1.3Gb home network not over the internet. It states that it's connected via Wireless AC on the 1.3Gb network yet the connection feels like it's dead. I can't stream anything on the home network to any other device in the home. On the internet, speed tests are only getting to around 20Mb where they got to my usual 150Mb before. If I disable this device and go back to the Wireless N adapter built into the PC the internet speeds are what they should be and I can stream DVD and Bluray quality on the home network but still not 4K, which is why I bought this. I wish I knew what happened to it so I could fix it. All I needed was a little extra available speed so I could stream 4K on the home network, it worked great for 10 days, but then something happened and now it performs much worse than my Wireless N connection. I've uninstalled the device, reinstalled it, disconnected from the network, reconnected multiple times, restarted the PC multiple times. Nothing works. It looks like I'll be sending this back for a refund and trying to find a different Wireless AC adapter. EDIT #2 3 Star: After messing with this for a couple of days something made me think of trying a System Restore. So I restored the PC to before I first installed this adapter. After the Restore I reinstalled this adapter and, of course, it works wonderfully. My Internet speeds are where they should be. I can stream DVD, Bluray and 4K quality movies over the home network with no buffering. It's working as well as it did when I first installed it. Now, do I keep it or still return it for not really being trustworthy? I have about 2 weeks still to be able to return it so I'm going to use it for a week at least. If it messes up so much as once it's going back. Edit #3 3 Star: Well I have 5 days left to return it and it did mess up just earlier today but it wasn't the adapters fault. I don't think anyway. Windows did an update and after that it had reverted all of the Network settings to Default. This messed everything up but once I got the settings back where they should be it worked again. Not really the adapters fault so I'm not going to blame it. One thing I have noticed though, and it's kind of annoying, is how the adapter connects after a reboot. After a reboot the adapter will show it's using Wireless AC protocol but it will be on the 2.4GHz band and a low channel, 3 for me, for about 10 minutes. After about 10 minutes it then jumps to the 5GHz band and a higher channel that's in the hundreds. So, for me, the Internet is very slow and home network video streaming is completely out until it jumps to the 5GHz band. I don't know why it doesn't start connected to that instead of the 2.4GHz band. I'm going to keep it, reluctantly, simply for the fact that when it does work it works very well. That said, if you've read this far and know of another brand or model that works solidly every time do let me know in the comments! ... show more
