I plan to install Ubuntu soon on my PC. I currently use a TP-LINK TL-WN822N wireless adapter. I want to know if it will work without additional setup.

  • For what it's worth, I have a TP-link wireless adapter (Model: TL-WN725N). It doesn't work very well at all with AES encryption, but it works fine out of the box with TKIP encryption (in Xubuntu), although the antenna (or lack thereof) isn't great. Mar 24, 2016 at 6:12

It should work with Ubuntu without additional setup. But kernel driver for this adapter may work unstable. I suggest to install a better driver from source.

sudo apt-get install git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install

This answer is applicable to hardware version 3.0 of this adapter with a Realtek chip. Previous versions should work well out of the box.

I packaged this driver to DKMS format and added it to ppa. If you instal it from there, you will not need to re-install it after kernel upgrades. It can be installed by

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtl8192cu-dkms

  • Basically: you need to access the internet to install the drivers to access the internet. Congratulations: we have a chicken and egg problem! But now, speaking seriously, that git seems like a great source of drivers, updated quite a lot. May 20, 2015 at 11:56

    The dongle will work out of the box, but not great.

  • I am trying to add a monitor interface on top of this device in Ubuntu 16.04 but iw does not even see it. Any tips? Otherwise, it connects to an AP and seems to work.

  • Oops: "E: Unable to locate package rtl8192cu-dkms" ... any idea why this might be? NB this is not straight Ubuntu, but Linux Mint Cinnamon 18.3 (meant to be a fork of Ubuntu) Jan 25, 2018 at 13:40

    I get "E: The repository 'ppa.launchpad.net/hanipouspilot/rtlwifi/ubuntu artful Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. " for 'sudo apt-get update', this is probably the reason the commenter above me gets 'unable to locate package'. Mar 1, 2018 at 21:51

Take a look at

https://help.ubuntu.com/community/HardwareSupportComponentsWirelessNetworkCardsTP-Link

Look for TL-WN822N


TL-WN822N

Please ensure that you also install linux-firmware package after installing Ubuntu.

If you still have issues please post results of lspci and lsusb commands.

    Linux-firmware is not needed, lspci is irrelevant, but good hardware version information.

  • This worked great for my TL-WN823N, too.

There are 4 different versions of this wireless adapter and they use different chipsets:

  • Versions 1 and 2 use Atheros AR7010.
  • Version 3 uses Realtek RTL8192CU.
  • Version 4 uses Realtek RTL8192EU.

To find out which version you have, take a look at the back of the adapter - it will say something like "Ver:3.0". Alternatively, use lsusb - my TP-LINK WN822N V3 identifies as "Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter".


If you have the Atheros-based one, the driver used is ath9k_htc and it should work out-of-the-box.

This page lists the drivers currently used for Realtek chipsets - essentially, they will all be replaced with rtl8xxxu at some point.

That said, while version 3 works out-of-the-box with the rtl8192cu driver, that driver is really bad (slow speed, disconnects occasionally). You'll want to install rtl8192cu-fixes to make it usable (which will also blacklist rtl8192cu).

I have no information about version 4, but RTL8192EU should work out-of-the-box with the rtl8xxxu driver on newer distros.

  • From what I understood from this and previous answers, if I have v3 I should use rtl8xxxu, since ppa:hanipouspilot/rtlwifi does no longer work and https://github.com/pvaret/rtl8192cu-fixes states that it is obsolote in favour of newest rtl8xxxu. Unfortunately, I do not get any clue on how to install that driver. Could you give more details, please?

  • For Version 4, (RTL81EU) you can install the driver from: github.com/clnhub/rtl8192eu-linux Without this driver I've much problems with very slow connections.
