Unfortuntately, Arch doesn’t support the TP-Link
TL-WN823N by default, so you have to install the drivers by hand.
Fortunately, you can find the drivers on Github. You’ll need
Installing after upgrade
If you’re run
pacman -Syu and your wifi has stopped working, run the following commands:
git clone https://github.com/Mange/rtl8192eu-linux-driver.git cd rtl8192eu-linux-driver sudo dkms add . sudo dkms install rtl8192eu/1.0
This will copy the driver into a system directory and register it with DKMS (Dynamic Kernel Module Support). This means that if you upgrade your kernel in the future, the driver will automatically be rebuilt.
Installing on a clean machine
If the machine that you need wifi on doesn’t have these packages installed, you can build the drivers on another machine and copy the built driver over via USB.
If the two machines have the same kernel installed, it’s as easy as following these instructions:
On the machine with build-essential
git clone https://github.com/Mange/rtl8192eu-linux-driver.git cd rtl8192eu-linux-driver make cd .. cp -r rtl8192eu-linux-driver /media/YOUR_USB
On the machine that needs wifi
cp -r /media/YOUR_USB/rtl8192eu-linux-driver . cd rtl8192eu-linux-driver sudo make install
At this point, reboot and you should have wifi. Once you have wifi, follow the DKMS instructions above to ensure that kernel upgrades don’t break your wifi.
If the two Arch machines that you have don’t have the same kernel version, you can edit the
Makefile to build for a different kernel. You’ll need to get the correct headers from the Arch archive and install them with
Then edit the
Makefile so that anywhere it runs
uname -r e.g. here, you replace it with the correct string. You can obtain the string by running
uname -r on the machine you want to install the driver on.
Makefile is updated, run
make and copy to a USB stick as normal.
