IMPORTANT - PLEASE READ:

Beginning on November 4, 2019, I will NO LONGER support people that have downloaded the source as a zip file. Using git has much more flexibility. In addition, there is much less liklihood that a user will contact me with a problem that is ALREADY fixed.

If your system says that /lib/modules/...../build does not exist, you have not installed the kernel headers, you have done it incorrectly, or you are not running the kernel for which the headers have been installed. The necessary steps are dependent on which distro you are using. Creating a new issue and asking at GitHub will not be productive.

Unsolicited E-mail sent to my private address will be ignored!!

If a build fails that previously worked, perform a 'git pull' and retry before reporting a problem. As noted, if you had downloaded the source in zip form, then you would need to get an entirely new source file. That is why using git, which downloads only the changed lines, is required.

Repository for the stand-alone RTL8192EE driver.
May offer much better performance than the kernel rtl8192ee driver, especially when used as Access Point.
Still, it will, with difficulty, barely surpass 50Mbps of uplink, in the best conditions.

To compile the driver, you need to have make and a compiler installed. In addition, you must have the kernel headers installed (usually package linux-headers or linux-headers-generic). If you do not understand what this means, consult your distro's documentation.

Depending on your distribution, you might need to run this as root.

make all

sudo make install

You must also blacklist the kernel driver, or it will override this one.

echo "blacklist rtl8192ee" | sudo tee -a /etc/modprobe.d/50-blacklist.conf

Now, tell the system to load the module on boot.

echo "8192ee" | sudo tee -a /etc/modules-load.d/8192ee.conf

Reference: TL-WN881ND v2
This device can broadcast on channels 1-13.
Using hostapd to manage your AP, set the proper ht-capab field for this device, which is:

HT_CAPAB=[RX-STBC1][SHORT-GI-40][SHORT-GI-20][DSSS_CCK-40][MAX-AMSDU-7935]

Optionally enable wideband, if you don't have neighbours:
Note that while this will result in a increase in network throughput it may cause clients further away to fail connecting.

HT_CAPAB=[HT40+][RX-STBC1][SHORT-GI-40][SHORT-GI-20][DSSS_CCK-40][MAX-AMSDU-7935] (for channels 1-7), or
HT_CAPAB=[HT40-][RX-STBC1][SHORT-GI-40][SHORT-GI-20][DSSS_CCK-40][MAX-AMSDU-7935] (for channels 5-13)

Currently there is no way to change transmit power in the driver with iw or iwconfig tools, as you would with other wireless devices.
However, you can still manually change the transmit power at compile time by editing the file hal/rl8192e/rtl8192e_phycfg.c and changing the lines below:

/* Manual Transmit Power Control 
   The following options take values from 0 to 63, where:
   0 - disable
   1 - lowest transmit power the device can do
   63 - highest transmit power the device can do
   Note that these options may override your country's regulations about transmit power.
   Setting the device to work at higher transmit powers most of the time may cause premature 
   failure or damage by overheating. Make sure the device has enough airflow before you increase this.
   It is currently unknown what these values translate to in dBm.
*/


// Transmit Power Boost
// This value is added to the device's calculation of transmit power index.
// Useful if you want to keep power usage low while still boosting/decreasing transmit power.
// Can take a negative value as well to reduce power.
// Zero disables it. Default: 2, for a tiny boost.
int transmit_power_boost = 2;
// (ADVANCED) To know what transmit powers this device decides to use dynamically, see:
// https://github.com/lwfinger/rtl8192ee/blob/42ad92dcc71cb15a62f8c39e50debe3a28566b5f/hal/phydm/rtl8192e/halhwimg8192e_rf.c#L1310


// Transmit Power Override
// This value completely overrides the driver's calculations and uses only one value for all transmissions.
// Zero disables it. Default: 0
int transmit_power_override = 0;


/* Manual Transmit Power Control */

The module can also be installed with DKMS. Make sure to install the dkms package first.
If you aren't updating from an older commit of the driver, there is no need to run the "remove" command.

sudo dkms remove 8192ee/1.1

sudo dkms add ./rtl8192ee
sudo dkms build 8192ee/1.1
sudo dkms install 8192ee/1.1
