TP-Link TL-WN822N

I found myself in need of a USB wireless adapter again, but wanted to get an N 300 adapter instead of an N150 adapter. I still wanted it to work as well as the Medialink USB adapter I previously reviewed. I decided to purchase the TP-Link TL-WN822N. The reviews on Amazon.com indicated this was an Atheros chipset, but the one I received was a Raylink. Apparently, there are three versions of this device and only version 1 and version 2 use Atheros.

The TL-WN822N was automatically detected on Ubuntu 12.04, 12.10, 13.04 and 13.10 (development release). I was disappointed though since it never achieved speeds above 150Mb/s. Though it never went below 150Mb/s so there is a chance that the speed is not being accurately updated.

The device does have two antennas and it should have greater range than the Medialink, but I have not put that to the test yet. I will write an update in the near future after the devices have been in used for a while.

IMG_2808IMG_2810IMG_2813The TL-WN822N is using a different chipset and driver, so I will have to research why the device is not achieving higher speeds.

My wireless router, the ASUS RT-N66U, is capable of supporting the speed so I will have to do some research as to why it is either not reaching or showing higher speeds.

    There’s a chance that the Wi-Fi channel width of your router is set to 20MHz instead of 40MHz on the 2.4GHz band, which limits the max throughput to 150Mbps, if I’m not mistaken.

    I also have the same router (RT-N66u) and on the 2.4GHz band, no Wi-Fi device at my home ever exceeds 150mb. That could be one of two reasons: 1) My channel width is set to 20MHz, most likely culprit or 2) None of my devices support 2 or 3-stream Wi-Fi.

    It’s possible your connecting to 5ghz over 2.4ghx or vice-versa. and you’ll never get anywhere near the rated speed
