Super easy to install and worked right away on my PC. The WiFi signal is much stronger now and the connection speed feels faster and more stable, especially for gaming and streaming. The antennas also help with range. Definitely a great upgrade for desktop computers without built-in WiFi.

This WiFi adapter is an effective but cost-effective way to add dual-band WiFi to a PC. I've found that it reliably maintains WiFi connections and has decent throughput. Additionally, the antenna is large and very adjustable which gives this adapter a big leg up on those adapters that have small and/or internal antennas. I am now using two of these on a regular basis.

It performs well, sustaining a 350 Mbps+ connection with a stock AT&T router 30ft away and 2 walls in the way. The built-in memory with the driver on it is very nice to have. It makes installation and setup very easy. The main issue I have had is that it can take 2min+ to establish a connection, and sometimes it needs to be unplugged and plugged back in to fix it. It also takes a while to connect to the 5GHZ band. It starts off at around 80 Mbps on the 2.4 GHz band and, after a few minutes, jumps up to the 5 GHz speed. It may be related to my distance from the router, but I haven't tested that.

200mbps ceiling no more! At our new home I had tried getting our xFinity wifi speeds to get anywhere near the wired speeds (routinely 600 - 800mbps with the ethernet cables strong from the router 50 feet to my office) and no matter what I did the wifi speed never went above 200 - 220mbps. What was weird is that a cheap $200 buck Lexmark Chromebook would get wifi speeds of 450 - 600 no problem (so, at least that saved me from contacting xFinity "support" since clearly that showed the router was working just fine.) I ordered a couple other USB wifi adapters (primarily based on reviews mentioning the sorts of speeds I was hoping, nothing else) with no luck. I finally asked Claude.ai what could be happening and it indicated I needed a 2mimo Wifi-6 compatible adapter and specifically recommended this one. I tried it on an older HP G1 desktop, first, with no increase in speed. I thought this wasn't go to work either but thought I would give it a try on a much newer PC. Lo' and behold, it worked PERFECTLY and the first Fast.com speed report was 580mbps. Since then the speeds have average 650 - 800mbps! (BTW, the reason the old PC's speed didn't increase is not only is it Windows 10, but according to Claude.ai the chipset of that machine isn't capable of supporting today's Wifi-6 demands.) The design is great and it took only a few minutes to install after downloading the latest driver. Not only was it a great price it the performance and the range saved from what I was preparing to do the following day, call the handyman to wire the house for wired ethernet (which would have easily cost $500 - $1000 bucks for all of the rooms I was resigning myself to needing ethernet drops!) Thank you, TP-Link! So glad Claude recommended your TX20U!

I've been using this thing for over 2 years with no issues at all with 300mbps speed. I got bumped up to 600mbps and it still works great for gaming (albeit some high ping) but while downloading games it's over heats every 2 minutes and disconnects. So just something to think about. I will leave it at 5 stars bc it gave me zero issues for over 2 years. But I am upgrading to the Archer Tx55e AX3000.

Bought this adapter since moving to my new house. My previous house was wired pretty heavily so I didn't have to rely on wifi. I got this adapter in hopes that I wouldn't have to cable much, since wifi works for all other devices in the house. At first everything seemed fine. I've used this adapter for my PC for ~4 months now, but over the last week, the disconnects started happening. When first connecting the device to my PC, it connects as a USB drive, and the install app for the driver is on the unit. This is actually pretty brilliant, since having to download a driver on a PC that doesn't have a network card can be challenging, if not impossible, unless you have another PC handy. The install goes really quick and installs v2.0.2.0 of the driver. The PC that I installed this on is ~8 feet from the wifi router. Signal is good between the unit and the router...when it's connected. The challenge I've had is that recently, the unit frequently just disappears from my devices. Occasionally, just unplugging and replugging the device gets it to show up and reconnect, but more often, I have to completely uninstall the driver, reboot my PC, reinstall the driver, then reconnect the adapter to my wifi. I've tried changing some adapter settings related to power management and that doesn't seem to make any difference. I tried different driver versions from the TP-Link support site, and I get the same behavior. I was having an even odder issue where when i tried to do any kind of high-bandwidth usage, like transferring files, or using a remote desktop tool (TightVNC), that would cause the adapter to just disappear again. That seems to have stopped after multiple reinstalls, but the disconnects continue. I've read a number of posts in forums about having to change a number of different settings on my wifi router, but to be honest, I shouldn't have to do that. I've got ~40 devices connected in my house, from smarthubs, to Amazon FireTV devices, to laptops and PCs, and a couple of Raspberry Pi units, and NONE of them required any changes on the router side. I've also seen some people compliment the "speed" of this device, but I'm not impressed. I have gigabit fiber internet, so I am not limited by bandwidth. Using other wireless devices in the house, I average ~400+Mbps download and ~330Mbps upload. The attached screenshot shows what I get when I run this with the TP-Link adapter. I ran the test several times just to make sure it wasn't an issue with any single test and the results average right around this 231Mbps mark download. The upload speed is on par with the other devices, but the download speed is just horrible, by comparison. This is really secondary to the disconnect issue though. 230Mbps isn't bad, in general, for most tasks, including streaming, so it's just by comparison to other devices that the lack of throughput shows. Lesson learned and money wasted. Still haven't decided whether to purchase another wireless adapter or to go ahead and just run the cable, but I wanted to make sure to warn others about the frequent disconnects. That has been a major pain in the butt. It's quite possible that I just got a flaky unit, but just know that this is an issue.

5/5 because this is genuinely a good product. It just did not work well for my specific situation. The issue was not the adapter itself. My house has older plaster walls with wire mesh in them, which absolutely destroys wireless signal strength. It basically turns parts of the house into a low-budget Faraday cage. Because of that, I ended up needing a much more powerful antenna setup for reliable performance. That said, the TP-Link adapter itself was easy to set up, detected networks properly, and seemed well made. In a normal house or apartment without my bizarre anti-WiFi wall construction, I think this would work extremely well. The dual-band support, external antennas, and WiFi 6 capability make it a great option for upgrading desktop wireless performance without opening the PC up for an internal card install. So while it was not the right fit for my environment, I still think it is a solid product and worth recommending. Sometimes physics wins.
