TP-LinkUSB Wifi Dongle 300Mbps High Gain Wireless Network Adapter for PC Desktop and Laptops. Supports Win10/8.1/8/7/XP, Linux 2.6.24 - 4.9.60, Mac OS 10.9 - 10.15 (TL-WN822N)

I'm always a little skeptical of claims made by inexpensive wireless devices but the TP-Link really did exceed my expectations. Here's the whole story...We recently upgraded to FiOS Quantum internet service but the wireless router supplied by Verizon didn't come close to supporting the transfer speeds the new connection was capable of. I added a TrendNet dual-N access point, TEW-637AP (highly recommended, BTW, and also purchased from Amazon TRENDnet 300 Mbps Wireless Easy-N-Upgrader (TEW-637AP)), and doubled the wireless speed. However, signal strength was so low that speed often dropped by 50% or more and the 58Mbps maximum wasn't close to the best. Now it appeared that the wireless USB adapter, a single antenna TrendNet TEW-644UB, may have been part of the problem. I was intrigued by the dual antennas on the TL-WN822N, thought it could be a better match for the dual antenna wireless access point and, given the low price, was certainly worth a try.The adapter arrived quickly and installed easily. (Be sure to follow the instructions to cancel Windows offer to search for or install the driver and run the TP-Link driver and setup utility **after** plugging in the adapter.) The adapter activated as soon as the software installation completed and opened the configuration utility. After selecting the TrendNet access point and entering the WPA security code, the TL-WN822N connected immediately.The first thing I noticed was the signal strength - Windows 7 wireless network connection status now shows signal quality of 80%. Even more impressive was the speed, now at a steady 130Mbps, a 225% increase.Don't hesitate if you're looking for higher wireless speeds but keep in mind that you will also need a dual antenna, dual-N (300Mbps) wireless access point to make the most of the TP-Link TL-WN822N. This was undoubtedly the best $20.00 I've ever spent on a computer.

Amazing little antenna for a desktop that needs a wifi adapter or a laptop that just needs a range boost. I do love that I SOMETIMES get speeds of 100Megabits per second (10 megabyte per second download speeds), but i do have a 300 megabit connection, and even when placing it right beside the router i only get around 90-100MBps. At around 30 feet away from the router speeds drop to 30-60MBps with around 2 concrete walls inbetween, you just need to find somewhere to place it to get a good signal. Someone tried to tell me that it was the usb ports affecting this, and it might be. but it is usb 2.0 so i dont really expect much anyways. I noticed that a few months after using it the usb port somehow got delicate and decided to not work. i have to make sure the cable gets absolutely no movement or else it cuts off which is silly since i hardly move it.For gaming i would say it is decent, i get 5-40 ping on average and am more affected by game server problems than network issues at my home. it picks up distant signals which is nice too. i like that the antennas bend down and sit flush with the device for storing in a bag or smewhere else. you can also discretely tape it under a desk. the drivers are all online, and its ultra lightweight and compact. i do need a replacement soon, but i think there might be something newer by the time i go ahead and purchase one. overall TP link makes amazing products, ive purchased multiple routers on newegg and this is my first wireless adapter from amazon. they have great driver support and i can confirm it works on OS X, as well as Windows, you just need to find the correct driver and use a wifi utility such as the "Green wifi utility".This is hands down one of the best investments i have made for my desktops networking capabilities.

I got this wireless adapter based on the reviews, and the extremely reasonable price (though lots of others are the same price or less). I decided I really wanted a good one, and ratings factored in heavily for my decision. The router arrived quickly. I am the go-to person in my house for computer repair - swapping out hardware, installing software, running anti-virus, etc. I have a pretty good idea of what I am doing for this kind of thing.When I originally tried to install the software for this piece of equipment, it seemed to install just fine. But when I checked the icon to see if it was working, the list of available connections indicated "Connected," but at the top of the list where it says if your PC is connected or not said, "Disconnected." Say what? How can I be both simultaneously connected and disconnected? And by the way, I didn't have internet access, so it was clearly disconnected.I uninstalled the software, then reinstalled it. I'm not sure what was different, though I did notice that after I clicked the correct button to install it, there was a very long delay of a good 10 to 15 seconds before the next screen popped up. I didn't recall that happening the first time (though I'm sure I installed it properly). In any case, be patient as it installs. I have a refurbished Windows 7 machine that is less than 6 months old so it should have gone quickly, but had that long wait.Once re-installed, it worked perfectly, and has been on our computer for a good week or so now with no issues. Our younger daughter watches a fair amount of YouTube and Hulu content, and it seems to work okay for that so far. The wireless adapter is a good 20 feet away from the wireless router, which is one full floor lower as well, and it has full five-bar connectivity. I gave it four stars due to the installation issues, and the fact that the instructions did not have a Q&A section that addressed the problem I had, so hopefully others will find this useful if they have a similar problem. But overall, now it's working well, and I'm fairly satisfied with it; just not the initial frustration.
