I have this WiFI dongle (Edimax EW-7811Un)
Is there an Ubuntu package I can use to get it working? If not, how can I get this WiFi to work?

This worked on Ubuntu 14.04 LTS and 14.10 (tested and works)
sudo apt-get update && sudo apt-get install git build-essential linux-headers-generic dkms git clone https://github.com/dz0ny/rt8192cu.git --depth 1
Currently, as of 22/04/15, there is a bug when installing this with GCC 4.9 or newer. To fix this bug remove line 1580 from
rt8192cu/os_dep/linux/usb_intf.c This line should read:
DBG_871X("build time: %s %s\n", __DATE__, __TIME__);
cd rt8192cu sudo make dkms
Reboot and you are done.
For later kernels ( 3.9 + ) this article on the Edimax site was very helpful... Paraphrased below
If you have issue(s) with the built-in driver, you can try this open source driver from github.
Plug in the EW-7811Un to your system's USB port (2.0 preferred), making sure your system has temporary Internet connection
Open a Terminal program and make sure your system is up-to-date
sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade
Note: You may need to restart your system if a kernel update has been installed.
Install the necessary packages to compile a device driver:
sudo apt-get install linux-headers-generic build-essential dkms git
Reboot, then clone the github repository:
git clone https://github.com/pvaret/rtl8192cu-fixes.git
Note: Right after "rt", it is a letter "l" (like Larry), not a number "1" (like 1980.)
Set up as DKMS module:
sudo dkms add ./rtl8192cu-fixes
Build and install the rtl8192cu driver:
sudo dkms install 8192cu/1.10
Refresh modules list:
sudo depmod -a
Blacklist the native kernel driver:
sudo cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/
Disable power management:
sudo cp ./rtl8192cu-fixes/8192cu-disable-power-management.conf /etc/modprobe.d/
Restart your system to use the new driver.
For removal, you can use the following commands.
sudo rm /etc/modprobe.d/blacklist-native-rtl8192.conf sudo rm /etc/modprobe.d/8192cu-disable-power-management.conf sudo dkms remove 8192cu/1.10 --all
Sure, on the page you gave there is a download link. Click that and it takes you to a list of drivers (scroll down a bit).
To make it easier, here is the direct download.
Extract them, then do
chmod +x install.sh
With an ethernet connection do:
sudo apt-get install --reinstall linux-headers-$(uname -r) linux-headers-generic build-essential git dkms git clone https://github.com/pvaret/rtl8192cu-fixes.git sudo dkms add ./rtl8192cu-fixes sudo dkms install 8192cu/1.9 echo "blacklist rtl8192cu" | sudo tee -a /etc/modprobe.d/blacklist.conf
Hello, since this is the first google result, answering here! thanks to this source!
*also heads up latest ubuntu version recognizes this device without any setup!
I found it here:
EW-7811Un_Linux_driver_v220.127.116.11>EW-7811Un_USB_linux_v4.0.2_9000.20130911>driver>rtl8188C_8192C_usb_linux_v4.0.2_9000.20130911.tar>here you will find makefile!
now get the location of this folder, and go to it on terminal! (for example
just to check type in " ls " (without quotes) to find that makefile is there
4. Now type these commands in your terminal
(should take a while here just wait until its done) then type
sudo insmod 8192cu.ko
and it should work!
To not have to do this everytime you start comp, put this in terminal aswell
sudo cp 8192cu.ko /lib/modules/
sudo insmod 8192cu.ko
sudo depmod -a
I think it is supported by default now.
I bit the bullet and bought one from thinkpenguin.com which are built for Linux and all major and not so major distros. It's plug and play without any fuss. We ended up needing a wireless extender as well owing to the massive outer walls in a 150 year old house. It was not too bad without it, but if you know where to look a good one can be had for under $30 and works like a charm. Signal strength is just a tad lower than being right beside the (fibre) modem.
