Edimax 7811-Un USB Wireless Adapter

[jeffroaltiere1]

Hey. So recently, I got a new wireless adaptor for my PC. It's an old Dell E310, and I tried using it on such, but it didn't work. I couldn't find much on the manufacturer's website that would help. Could anyone help me out here?

Oh, also, the adaptor did come with a disk.

Which version of Buntu are you using?

[jeffroaltiere1]

I'm using 13.10.

[mörgæs]

- and the full name of the Edimax adapter?

In general you should post much more information. Noone can help you based upon what has been posted so far.

[praseodym]

Please open a terminal with CTRL+ALT+T and show the outputs of these commands:

lsusb #with the stick plugged in!
lsmod
iwconfig
cat /etc/resolv.conf

Does LAN work?

[jeffroaltiere1]

I'm using an Edimax 7811-Un.

As for the commands ran:

I cannot find whether LAN works or not. My router is too far away and I don't have a long enough cord to run to it.

@praseodym--

I think he needs to remove from /etc/modules or blacklist rtl8192cu as it doesn't drive his device.

This driver does, but you and I would structure the procedure a bit differently: http://askubuntu.com/questions/36497...us-doesnt-work

Here is my test:

$ modinfo rtl8192cu-fixes/8192cu.ko | grep 7811
alias:          usb:v7392p7811d*dc*dsc*dp*ic*isc*ip*in*

We now return you to your regularly scheduled guru!

Download these files and save them in "Downloads" and extraxt the tarball there:

https://dl.dropboxusercontent.com/u/...u-fixes.tar.gz

http://de.archive.ubuntu.com/ubuntu/...buntu4_all.deb

Installation:

cd ~/Downloads/
sudo dpkg -i *.deb
sudo dkms add ./rtl8192cu-fixes
sudo dkms install 8192cu/1.8
echo "blacklist rtl8192cu" | sudo tee -a /etc/modprobe.d/blacklist.conf

Reboot

Edit: New Link!

[jeffroaltiere1]

Okay. It took a while, but after a few long minutes, it all worked. I rebooted, and now I'm connected. Thank you all so much for your help!

[praseodym]

Check if all necessary stuff is installed:

sudo apt-get install linux-headers-generic linux-headers-$(uname -r) build-essential

Edit: With this the driver will be compiled automatically after a kernel upgrade
