Summary: This card's drivers are Windows-only. If you searched for it and think it'll work with airmon-ng or reaver, it will NOT. This is version 4.1, which uses the Realtek RTL8192CU chipset. There are two drivers for it for non-Windows systems. You can get the official Realtek driver (Linux and OSX), or search for "compat-wireless" driver (Linux only, but better).
Summary: This unit did not work with my Onkyo NR 616 receiver. Some discussion boards thought it might. I tried it. It did not. I updated all the firmware and did the setup a zillion times a zillion different ways. I'm fairly tech savy...I could not get it working. That said I was able to get it working on my computer fairly easy. It did not work on my mac but I was able to boot into windows 7 and it worked fine.
Summary: We have been using this for the past year or so, for my sister s computer and I have to say the wi fi is awfully slow on it.. The distance is about 10m away, but other laptops have better reception in her room than her desktop.
Summary: i do not know if there is a fix for this problem i have the version 2.8 drivers does not work with my computer . it is a hassle to replug after every shutdown i have other tp-link product for my XP and it works great.. just no luck with win7 ultimate 64bit ** i give this device 1/5 stars because there is no way to find the order id on the receipt to write a review for 1&2 stars
Pros: this device works , great signal
Cons: this device did not properly install on win7 64bit, this device did not reconnect after shutdown, this device require to replug into computer after every shut down
Summary: I purchased this wireless adapter to transfer data from my laptop to main server and back at a speed faster than "G" speed. My laptop has (at least I thought) a weak antenna and is only capable of wireless-G speed. This adapter should provide me with higher "N" transfer speed and better reception. I installed the drivers on a Windows 7 32bit machine without issue.
Summary: amazing product from amazon. i have purchased first time from amazon, good service from a amazon inspired me to visit amazon site frequently. coming to product it is a good product, nice connectivity with pretty good speed with out break in the range of 8 to 10 meters. beyond this range connectivity either break or very less. new buyers can note this point, because the main purpose of buying the product is for good connectivity and range.
Excerpt: Нормальный такой wi-fi свисток. Частых обрывов замечено не было, скорость относительно нормальная, но в купе с роутером той же фирмы ожидал большего, по крайней мере в скорости. А так ничего за эти деньги.
Pros: Выносной адаптер, цена+скорость, обрывов практически не замечено.
Cons: Да нету вроде. Скорости бы побольше, но многое от роутера зависит.
Summary: Compre hace un par de años este TP-LINK TL-WN821N porque me hacia falta un receptor Wi-Fi para el ordenador de sobremesa y asi quitarme el engorro de andar llevando cables desde el router de entrada hasta la estancia que utilizo habitualmente como despacho o lugar de trabajo. Su instalación es muy sencilla porque es Plug and Play, esto es, que lo conectas y se instala solo.
