TP-Link Archer T2U 11AC USB WiFi Adapter - Dual Band 2.4G/5G AC600 Wireless Network Card, WiFi Dongle, Mini Size, Supports Windows (XP/7/8/8.1/10), Mac OS (10.7~10.14)

So my laptop's wifi stopped working a while back. I need it for work and reports and email while traveling. So this wifi adapter works perfectly!! The signal is great it gets higher ranges and at a good distance. The installing portion is so easy and your computer does all the work it takes no longer than a few minutes. You don't notice it as I leave it plugged in my external USB hub, I see it flashing and currently using it now with my phone's hotspot, where before this special item I had my phone plugged in and it's just horrible when its plugged into a laptop for internet use. So go BUY it Now!!

I purchased this for my older but still going strong laptop but was met with a few problems the main being that it seemed like it was throttling my laptop's CPU which is the biggest and the included software which I liked because of the display and ease of use would be at a constant 5-25% of CPU use, you can use it without the software if you want but I figured I'd try it also it comes in slow mode I wasn't getting high speeds until I added the software though the speeds weren't much better so I had to manual adjust it from the computers networking area which too a day or 3 to figure out switching back and forth between different modes I couldn't figure out how to get it to enter AC mode so I left it in N mode so it would at least be fast of course I did accidentally get it stuck in G more which I had to fix I finally figured out how to get it into AC mode and was getting nice speeds of 30-50 or so Mbps because of the 2.4 so it took me a good while to figure out how to get it to enter 5ghz mode as well as I eventually did and was able to top out at 100-120mbps although sadly it didn't stay that way and was constantly switching on me and the speed would randomly go down do I was forced to leave it in 2.4ghz which was fine considering my computer could only max out at 20mbps although all the throttling and uninstalling reinstalling the software made me decide it wasn't for me and that this device would probably work a lot better on newer computers rather than older so I decided to return it. Other side notes the installation pamphlet and disc came in Korean if I remember correctly but that wasn't that important because you can easily understand the pictures and installation CD even if it's in a different language and or download it from their websjye. Another side side note is in the networking where you change the modes and stuff on my computer was Japanese and one in Chinese I believe which also wasn't a problem because if you've read all of the recent stuff you'll know that I was able to figure it out through trial and error over the course of like 3 days or so because I wasn't keen on wanting to mess with it at that moment. Overall I like the design and I think it'd work better on a newer computer than an older one so that's something to take into consideration if you've made it this far in it read the headline.

Bought this to add 802.11a capability to an older netbook running Windows 10. The adapter was recognized without the need to install any drivers and it saw and connected to the router's 802.11n and 802.11a signals without difficulty even though this computer is in a remote part of the house. No dropped signals or other problems. Maximal speed tested with speedtest.net is much less than the rated capacity of the adapter due to the computer's limitations, but is adequate and the reliable connections to both types of signal met the purpose of this upgrade. It is also reasonably compact in the USB port making it less likely to be pulled out or broken when the computer is moved around, but it does protrude significantly so care is required.

I just installed this in a Windows 8.1 64-bit system. Unfortunately the computer blue-screened while installing the drivers (pretty rare for Windows 8.1). Not good. It did reboot OK and I did manage to get the adapter to work.... but minus one star for the blue-screen. It makes me question the driver quality.It does see my 5GHz network and does connect at high speed to it. The device itself is surprisingly small.So, for now, 4 stars due to the blue-screen... but if it continues to work without issue for an extended period of time then I may raise it to 5 stars.

I bought this USB adapter for network access since my built-in WiFi card on my laptop was no longer reliable. The adapter worked fine at first and the 802.11AC speeds were nice. After a month of occasional use I noticed the adapter would get ejected (USB function) by Windows periodically. Eventually, the adapter stopped responding altogether. I've tried reloading drivers several times but no positive results. Windows 10 now recognizes the device consistently but it does not pick up my two WiFi networks. Cellphones and other computer equipment have no problems connecting to my networks.If you buy this adapter make sure you register right away or save your packaging. You can only take advantage of the two year warranty by having the serial number available and it's not printed anywhere except on the packaging. I have a question in the the TP-Link Support group and will update here if I get positive results.Update:TP-Link assisted me with getting the product registered so I could use the 2-year warranty to replace the failed adapter. It was a fairly straight forward process but I would not bother calling 800 number support line; I was disconnected twice. I worked through the online chat feature and after about 30 minutes of chatting and providing screenshots TP-Link issued an RMA number. I received the replacement today. I will add a star for the customer service element; I was extremely skeptical. We'll see how long the replacement will last.
