Hope that helps. I did all of that yesterday, too, and still don't have a clue how to make Ubuntu see the USB Network Dongle. Thanks.

Hi,

install the driver via (Installation for Ubuntu until 11.04):

sudo apt-get install --reinstall linux-headers-$(uname -r) linux-headers-generic build-essential dkms
wget http://media.cdn.ubuntu-de.org/forum/attachments/2844083/rtl8192cu-3.1.2590_dkms.tar.gz
sudo tar xvf rtl8192cu-3.1.2590_dkms.tar.gz -C /usr/src
sudo dkms add -m rtl8192cu -v 3.1.2590
sudo dkms build -m rtl8192cu -v 3.1.2590
sudo dkms install -m rtl8192cu -v 3.1.2590

Reboot and check:

uname -a
lsmod
iwconfig
dmesg | grep r8
sudo iwlist scan
iwlist chan

Hello,

I think you may want to see what occurred from entering the above commands.

I kind of have a feeling that you knew what those responses would be from what I reported in my former post.

Oh, also, I noticed that it lists the pcmcia 35973 as 0. I'm not sure what that means, but I do have a device plugged into one of the two pcmcia slots that has two USB 2 ports, and a power plug port for an external USB 2 hub. I have my mouse plugged into one of the ports, and it works fine. I have the USB Network Dongle plugged into the other port.

Sorry, I keep thinking of things that might be important. Before I loaded Ubuntu 10.10 onto this laptop, I had been using Windows XP. While using XP, I had a NETGEAR WG511 v2 network card plugged into the other pcmcia slot. It worked well, but I couldn't get Ubuntu to recognize it either, even trying the commands with ndiswrapper. I still have the drivers for that card, but they never got installed.

Was the download of the "tar.bz"-file successful (100 %) with "wget"? If not, try the direct link:

http://media.cdn.ubuntu-de.org/forum...90_dkms.tar.gz

and remove the first file

It downloaded ok from the direct link, but when I tried to unzip the file, I got this Error;

gzip: stdin: unexpected end of file
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now

Not sure what that's all about, as I have already used the tar.gz unzipper on other files.

Sorry, I did it wrong. When I downloaded the first time, I had it save the file in my downloads folder, then I moved it to my desktop and tried to extract it there. I decided to try again, and I just had Archive Manager open the file, instead of just saving the unzipped file. Archive Manager has it open. I'll try those command lines again.

The file is unzipped, and opened, but I'm still getting the error I posted before when I try to run the Terminal command.

Move that unpacked folder to /usr/src/ via

gksu nautilus

and continue with

sudo dkms add ...

Frustrating, eh? I really appreciate your help. Awaiting your instructions.
