TP-LinkAC1200 Wireless Dual Band USB Adapter (Archer T4U V1)

They are working great for me! I say "they" since I bought 2 of these, one for each of my PC's that I recently upgraded from Windows 7 to 10. One note of interest - I did the Win 10 upgrades in mid-April 2016, so I think the Win 10 changeover has already worked through many of the issues others have noted from older installs.I had no issues upgrading either of my PC's to Win 10 other than the wifi went wonky on both after completing the installs. I previously was using ancient Medialink wifi adapters and after doing a little research found that they were not going to cut it with Win 10. I already have an Archer / TP-Link C9 router, so I looked into Archer / TP-Link wifi adapters since I have been very pleased with the C9. I ended up buying this one due to the features and reviews, though was a little perplexed by some of the negative reviews.In my case though, they were both totally plug and play with Windows 10. I did nothing other than eject the previous wifi adapter using the Windows eject hardware icon, then installed the new Archer T4U and Windows did the rest. Totally plug and play. Again I think that maybe since I waited to upgrade Windows until mid April that they worked out the previous issues people were having.I have one of them on 5GHz (the computer next to the router) and the other on 2.4GHz (the one farthest from the router). Both are working flawlessly, no drop outs, no need to reset or anything like that. And I'm getting speeds about 10% above what my ISP quotes, so really happy with the speeds I'm getting on both bands.I did not install any of the Archer software or drivers at all, I am just using whatever Windows 10 setup for them. I was ready to have to download drivers based on what others have said in their review, but in my case they were totally plug and play - could not have been easier.One thing to mention is that these are pretty big. I ended up using the nice extender cable that came with and plugged that in to open USB3 ports on the computers and then plugged the T4U's into the other end of the cables (note that the cables are directional - you can only plug them in one way). The extender cables are really nice and are a heavy gauge. I like this setup so that I can put the wifi adapters where I can see them so I can see the heartbeat light just to make sure all is well.Overall I am completely satisfied with the T4U's working with Windows 10. I am getting great speeds and 100% uptime so far in over a week on both computers. Not sure if they are working so well since I have an Archer C9 router, or if it is because I did the Windows 10 update recently after Microsoft fixed previous install issues, but in any event I am very happy with the purchases. Thanks for reading. (should I run into any issues down the road I will update' this review).

The TP-LINK AC1200 works in Linux Mint 18 Sarah.However it is not plug and play.Here is my experience.I wanted to convert a 13 year old computer running windows XP to a dual bootwith Linux and windows. The idea being to use the computer for email and browsing.Here were the requirements.- bring up Linux with TP-LINK usb wifi connector.- no Ethernet connection is available on the 13 year old computer.- computer is e-machine with 64 bit AMD processor.Linux installed in a few hours after creating a DVD obtained from a Linux mint server. DVD was created on a windows machine. Because there was no Ethernetconnection, no drivers were able to be downloaded from the Linux Mint serverduring installation.experience- I ordered The TP-link AC1200 wireless Dual Band USB adapter.The amazon web sight indicated that it was Linux compatible.- Upon receiving and opening the package the instruction manual has nohelp for Linux. The box doesn't say Linux compatible, only windows andMAC OS. This was of concern to me as it was not consistent with theamazon website offering.- The quick install instructions were only for Windows and MAC OS. Nomention of how to install for Linux.- I looked a little closer at the amazon reviews and some indicated thatthey had to return the device because it wouldn't work in their Linux system.- I searched the web and found one person's post which indicated thatTP-LINK had released a driver in October 2015. I went to the TP-LINKweb sight and found their driver. This was not easy to find on the TP-LINKweb sight, however I did find a driver, composed as a zip file, whichI was able to down load. (Using a Windows system. The idea here is toport the files to the Linux system using a USB stick)- After extracting the drivers, I found a pdf readme file which containedsome rather complicated instructions on how to install the driver. I foundthese instructions rather intimidating. Even though I am an engineer. (Ibelieve that these things should be somewhat simple.)- I searched the INTERNET a little more. Some people reported that using theTP-LINK device drivers didn't work for them. The drivers on the TP-LINKsight were for an older version of LINUX (release 3.16). However onesight indicated that some talented individuals had re-enginneered thedrivers and place a working driver for the AC1200 on the GIT repository.This was a reference to March 2016.- So I went to the GIT repository and was able to download a zip filevia the windows system.- I unzipped the files. I also compared the files and although much ofthe source code was the same, they two drivers were vastly different.- I decided to go with the newer binary by that talented group of people.Here is the reference where I found the information.[...] //sempike.blogspot.com /2015 /09 /linux-mint-ubuntu-compiling-ac1200.htmlI suggest following the UPDATE portion which led me to my resolution.There it instructs you that you may download the latest driver for the AC1200on the following Git-hub link:[...] //github.com /abperiasamy /rtl8812AU_8821AU_linuxWhich is the one that I successfully used, as follows:a.) down load the driver zip file to a windows machine.b.) expand the zip file.c.) copy files to a USB stick.d.) copy the files to a directory on the Linux machine.e.) use the following commands in a Linux terminal window to buildand install the driver. (be careful with your spelling)You will find these in the README.md file found in the driver directory.NOTE: you need to be in the drivers directory when these are executed.sudo cp -R . /usr/src/rtl8812AU_8821AU_linux-1.0sudo dkms add -m rtl8812AU_8821AU_linux -v 1.0sudo dkms build -m rtl8812AU_8821AU_linux -v 1.0sudo dkms install -m rtl8812AU_8821AU_linux -v 1.0f.) reboot Linuxat this point the TP-LINK wifi connector will come up with a green blinking led light.You may need to press the WPS buttons on the USB device and your wifihub to get them to communicate.g.) left click on the network icon in the tray on the lower left.h.) select "network connections"i.) add a wifi connection.You should configure the connection with the proper security.typically SSL with a password you placed on the hub.After the above my system worked and I was able to browse the INTERNETand configure e-mail services, via wifi.In conclusion, making this work on a LINUX system is not for the casualuser. TP-LINK states that their device driver may not work on any particularflavor of Linux and that they don't guarantee that it will work on your system.The above is an example of one successful Linux installation.The drive installation, with web searching and all, took 3-4 hours. I am hopingthat this post will save you some time.Good luck.P,S, apparently amazon doesn't allow links in reviews. (take the spaces out)Updated rating from 3 to 4 due to working great after 2.5 months.
