## Realtek 802.11ac (rtl8812au)
|
|
|
|
This is a fork of the Realtek 802.11ac (rtl8812au) v4.2.2 (7502.20130507)
|
|
driver altered to build on Linux kernel version >= 3.10.
|
|
|
|
### Purpose
|
|
|
|
My D-Link DWA-171 wireless dual-band USB adapter needs the Realtek 8812au
|
|
driver to work under Linux.
|
|
|
|
The current rtl8812au version (per nov. 20th 2013) doesn't compile on Linux
|
|
kernels >= 3.10 due to a change in the proc entry API, specifically the
|
|
deprecation of the `create_proc_entry()` and `create_proc_read_entry()`
|
|
functions in favor of the new `proc_create()` function.
|
|
|
|
### Building
|
|
|
|
The Makefile is preconfigured to handle most x86/PC versions. If you are compiling for something other than an intel x86 architecture, you need to first select the platform, e.g. for the Raspberry Pi, you need to set the I386 to n and the ARM_RPI to y:
|
|
```sh
|
|
...
|
|
CONFIG_PLATFORM_I386_PC = n
|
|
...
|
|
CONFIG_PLATFORM_ARM_RPI = y
|
|
```
|
|
|
|
There are many other platforms supported and some other advanced options, e.g. PCI instead of USB, but most won't be needed.
|
|
|
|
The driver is built by running `make`, and can be tested by loading the
|
|
built module using `insmod`:
|
|
|
|
```sh
|
|
$ make
|
|
$ sudo insmod 8812au.ko
|
|
```
|
|
|
|
After loading the module, a wireless network interface named __Realtek 802.11n WLAN Adapter__ should be available.
|
|
|
|
### Installing
|
|
|
|
Installing the driver is simply a matter of copying the built module
|
|
into the correct location and updating module dependencies using `depmod`:
|
|
|
|
```sh
|
|
$ sudo cp 8812au.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
|
|
$ sudo depmod
|
|
```
|
|
|
|
The driver module should now be loaded automatically.
|
|
|
|
### DKMS
|
|
|
|
Automatically rebuilds and installs on kernel updates. DKMS is in official sources of Ubuntu, for installation do:
|
|
|
|
```sh
|
|
$ sudo apt-get install build-essential dkms
|
|
```
|
|
|
|
The driver source must be copied to /usr/src/8812au-4.2.2
|
|
|
|
Then add it to DKMS:
|
|
|
|
```sh
|
|
$ sudo dkms add -m 8812au -v 4.2.2
|
|
$ sudo dkms build -m 8812au -v 4.2.2
|
|
$ sudo dkms install -m 8812au -v 4.2.2
|
|
```
|
|
|
|
Check with:
|
|
```sh
|
|
$ sudo dkms status
|
|
```
|
|
Automatically load at boot:
|
|
```sh
|
|
$ echo 8812au | sudo tee -a /etc/modules
|
|
```
|
|
Eventually remove from DKMS with:
|
|
```sh
|
|
$ sudo dkms remove -m 8812au -v 4.2.2 --all
|
|
```
|
|
