Ubuntu 14.04 LTS and TP-Link TL-WN823N cut Wi-Fi speed. How to be?

Question

Iron

Good day to all.
Help out guys. In short, I almost moved from Windows 8.1 to Ubuntu 14.04 LTS, and found that my Wi-Fi connection speed was unrealistically cut. On Windows, everything is extremely good - 50-55MB / s, and on Ubuntu - 0.25 MB / s.
Plus, the network falls off from time to time. With a tambourine on the forums already tired of running, it remains only here.
Wi-Fi adapter: TP-Link TL-WN823N (USB)
And yes, this happens on all versions of Ubuntu, I don’t know what to do anymore.
Help out guys. Thanks in advance!

First, make sure that all proprietary device drivers are installed in the Software and Updates application.

git clone https://github.com/Mange/rtl8192eu-linux-driver.git
cd rtl8192eu-linux-driver
sudo su
apt-get install git linux-headers-generic build-essential dkms
dkms add .
dkms install rtl8192eu/1.0

If nothing works, you can try:

cd /usr/src/rtl8192eu-1.0
nano Makefile

Change the lines to:

...
CONFIG_PLATFORM_I386_PC = n
...
CONFIG_PLATFORM_ARM_RPI = y

AND:

make clean
make
make install
modprobe -a 8192eu

The instruction is taken from here , in the direction from this page.
If all else fails, there is still no reason for despair. Perhaps installing this driver will help you. I went through this procedure on two computers, with Ubuntu 16.04 and 17.10, and in both cases I had to repeat it in different sequences. As a result, on the last computer, I found out that I was testing the speed of the Internet with a wi-fi flash drive plugged into usb1.0 :-)
