(SOLVED) Realtek RTL8192cu help

[owh]

Hi AlexCa

I had almost the same messages as yours:

##################################################
Compile make driver ok!!
##################################################
Authentication requested [root] for remove driver:
ERROR: Module 8192cu does not exist in /proc/modules
Authentication requested [root] for insert driver:
insmod: error inserting '8192cu.ko': -1 Device or resource busy
Authentication requested [root] for install driver:
install -p -m 644 8192cu.ko /lib/modules/3.0.0-12-generic/kernel/drivers/net/wireless/
/sbin/depmod -a 3.0.0-12-generic
##################################################
The Setup Script is completed !
##################################################

However I didn't have the error below:

insmod: error inserting '8192cu.ko': -1 Device or resource busy

Even with the rest of the "error" messages, the driver is indeed installed and works. You may want to try to proceed with mads's further instructions:

Code: Select all

sudo modprobe -r ndiswrapper
sudo ndiswrapper -e net8192cu
echo "blacklist rtl8192cu" | sudo tee /etc/modprobe.d/blacklist-rtl8192cu.conf
echo 8192cu | sudo tee -a /etc/modules

Try restart and see if thing works. You can further try:

Code: Select all

sudo insmod 8192cu.ko

I had to do:

Code: Select all

sudo rmmod rtl8192cu

before the installation script could success.

Hope above suggestions provide you with something to try further and hope you will make it work soon.

I did it! im not sure how but i did!

I think i've just repeated the steps from my previous post but with the adapter unplugged and then i removed the rltwifi folder that i've copied from linux mint cd!

Then i followed this steps (to the wireless be available after each reboot):

Code: Select all

echo "blacklist rtl8192cu" | sudo tee /etc/modprobe.d/blacklist-rtl8192cu.conf
echo 8192cu | sudo tee -a /etc/modules

Thanks owh only now i've seen your post, any way i'll keep this all thread for future reference!

Thanks everyone, Linux rules

Just another person here to say thanks to mads for the blacklisting instructions. They worked like a charm!

Thanks for this, you solved my problem for me. Did the same as you, then tried it with the wireless adapter unplugged, and voila!, it worked!

For those who are looking for a solution and stumble upon this thread: confirmed on LMDE with kernel 3.2.0-3 (64-bits).

I created this bash in the same directory of the driver's install.sh file:

Code: Select all

#!/bin/bash
# Download driver for rtl8192cu from Realtek:
# http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=48&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true#RTL8192CU

# Unpack driver and save this file next to install.sh

if [ $UID -ne 0 ]; then
  echo "Please, type root password..."
  su -c "$0 $@"
  exit
fi

apt-get install linux-headers-`uname -r`
apt-get install build-essential
rmmod rtl8192cu
chmod +x install.sh
./install.sh
echo "blacklist rtl8192cu" > /etc/modprobe.d/blacklist-rtl8192cu.conf
echo 8192cu >> /etc/modules

I made an account just to say thank you for this script, and everybody in this thread for figuring this out. Not only have I had problems with the RTL8192cu driver, but I have an Asus N13 with this chipset in it and would you believe Asus' own site gives you drivers for the RT2870 chipset instead when you pull up the support page. Crazy when you can't even get the right driver from the vendor.

Anyway I found this fix to work great with Ubuntu 12.10, even though I'm not an Arch user I just had to drop in and show my appreciation.

First of all: welcome to the Linux Mint forum and secondly, I'm happy that it worked for you.
So, don't feel pressured to try one of LM's tastes

I have a TP-Link TL-WN725N running in ubuntu 12.04, and after installing the RTL8192cu and blacklisting the kernel driver as advised all worked again as it did with windows. As someone posted before, I just registered here in order to greet the guys who made this possible. Thank you Mads and Monsta for sharing your knowledge with everybody!

[tinobin]

And of course Shoelje (sorry, but I didn't read this part of the thread until now)

[Schoelje]

Don't worry about it, tinoblin.
I'm glad it worked out for you.

Hi, I have stumbled on to this as I recently purchased a Netgear N150 Micro USB and have had endless problems with it

Now some of the issues could be I am offically below the class of n00b but I despise MS and have been using Ubuntu for years on my laptop with no issues at all.

I have now made a xbmc box for my lounge and thought wireless... before i consider having to use MS can someone please help me I would rather never watch tv again than have a MS media center.

I'm using a Dell Optiplex 755 and am on the LM Nadia 14

I have followed the instructions here but i still can't get it to work. (I also dont know how to use the bash script above) plus I have no idea what state the computer is in now I have tried some many solutions

Please help
