I'm using the TP-Link WDN4800 under Ubuntu 11.04. The adapter was recognized immediately by the OS, and a wireless connection was established. However, the connection speed was very slow, usually about 2Mbps, as measured on [...].(The other pieces of connectivity are CableOne 50Mbps service, a Motorola Surfboard SB6210 cable modem, and a Asus RT-N12B1 b/g/n wireless router. The PC I'm testing is not very close to the wireless access point; Ubuntu reports link quality at 52/70.)But it turns out there is a fix. In a terminal window, type:sudo -s gksu gedit /etc/modprobe.d/ath9k.confThis will open the ath9k.conf file; in my installation, there was no such file, so a new one was created. Add the following line:options ath9k nohwcrypt=1Save the file and reboot.Averaging five tests, my wireless connection speed increased to 17Mbps, a substantial improvement. For comparison, a wired Ethernet connection averaged about 38Mbps. I'm inclined to think your result with the WDN4800 might be a bit better with a stronger wireless signal.UPDATE January 4 2013: I've had problems with very large downloads -- the connection drops. I discovered this downloading Ubuntu ISO images. The problem doesn't occur using hard-wired Ethernet, so I assume it's the WDN4800.

Easy to installBlazing Fast Wireless ConnectionGetting 97% reception through 2 walls and about 40ft from my Asus Dark Knight U66 at 5Ghz and 450mbps. vs. about 46% with my previous G class wireless cardDramatically increased my upload ability with utorrent (partially due to the Dark Knight Upgrade above, which also comes highly recommended)Great price for the performanceTriple Antenna Setup is great for the receptionReally can't go wrong with this card assuming you have the router to take advantage of the bandwidth this card offers, otherwise might look into a cheaper card that suits your router, however i haven't tested this card myself with an older router to see if it makes much difference.

Bought this to use with my ivy bridge hackintosh running Mac OSX 10.7.4 . Works perfectly, just plugged it in, no drivers or configuration needed. Couldn't be simpler, signal with my airport extreme seems good!
