Ubuntu – Compile and install rtl8192cu driver

driversrealtekwireless

Can someone help me with this problem ? I am new to Linux, so I do not know commands and I never did something like installing or compiling with command-line.

I bought WiFi adapter from Edimax, model EW-7811UN for my PC (not laptop, so I do not have wifi card, only ethernet). When I go through guide on CD, I came across a version of kernel. It said I need version 2.6, but I have 3.5.0-22-generic.

I got errors like I do not have file or folder etc. Can someone tell me where I can download compiled driver and where I need to put it? Or some other advice. I don't want downgrade kernel when it is not necessary.

If you run into this problem, what worked for me was installing the following driver: https://github.com/pvaret/rtl8192cu-fixes

From the README.md file:

Installation

Ensure you have the necessary prerequisites:

sudo apt-get install linux-headers-generic build-essential dkms

Clone this repository:

git clone https://github.com/pvaret/rtl8192cu-fixes.git

Set it up as a DKMS module:

sudo dkms add ./rtl8192cu-fixes

Build and install it (this version number may change, it is .11 as of November 07 2019)

sudo dkms install 8192cu/1.11

Refresh the module list:

sudo depmod -a

Ensure the native (and broken) kernel driver is blacklisted:

sudo cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/

And reboot. You're done.
