I can't install driver for edimax EW-7811Un USB wireless adapter
Hi, I am completely new to linux. So please be patient with me, I would like to learn linux but don't have any experience with it so far.
Although I have a windows 7 laptop, I also have an old hp compaq nx6125 laptop running windows XP. Since Microsoft are ending support soon I decided I would try linux on the old laptop.
Although there is wireless built into the laptop, it is very old spec so I bought an edimax EW-7811Un USB wireless adaptor.
I inserted the wireless adapter and also a LAN cable I have installed zorin-os-6.2-lite.
The OS installed ok but zorin is showing no driver for the EW-7811Un.
My question is how do I install the driver, I have no experience with linux so if there is any step by step guidelines I would be very grateful.
I do have the install CD that came with the wireless adaptor but I don't know how steps to install the driver.
Should I have installed the OS without the LAN network cable? Should I re-install OS without the LAN network cable to see if a driver is installed during installation?
Thanks for your advice, I re-installed the os and made sure the wireless adapter was in laptop but I didn't put in the LAN cable to see if this time it would recognise the adapter since it didn't recognise it with the LAN cable plugged in during the earlier install.
during the new install it did identify I had the...
Edimax 7811un 802.11n USB adapter
and it also identified the build in wirelss adapter ...
Broadcom corp BCM4318 802.11g adapter
I don't think this was identified during the first install with cable in place.
..but after install neither wireless adapters are shown in the Network Connections, wireless tab.
I ran the scripts you suggested and the output is in the attached file.
Basically you would use the command line utility that came with Zorin OS.
If Zorin is Debian or Ubuntu based than the your cmdline utility would most likely be "APT"
This is just an an example here for you to understand.
Let's say that you have a radeon card and the driver is called catalyst c43_x86_4.
To install that driver you would open the terminal and execute this command:
Code:
cd Downloads
sudo apt-get install catalyst c43_4
Upon doing so you would be prompted for your root password.
After typing in your password hit ENTER.
Before you run that command you should download the driver to your Downloads directory.
To do that you would have to tell the terminal where that driver is like so:
Code:
Cd Downloads
(Use "ls" to list what's in your directory)
CD stands for change directory.
When you have time read the documentation for your distribution it will help you to understand how things work.
Go to http:\\zorin-os.com for more information.
Hi, thanks for taking the time to explain things to me, it is much appreciated.
There was an installation CD came with the Edimax 7811un 802.11n USB adapter. And there is a folder called Linux Driver which contains lots of files including a compressed file called "rtl8192CU_linux_v2.0.939.20100726.tar" but I'm not sure which file I should copy to the downloads directory.
I zipped this folder to "Linux_Driver.7z"and I tried to attach it to the post, but received an error. the file size is only 1,996kb so not too big, but perhaps only text attachments are allowed for posts?
There is a link at the bottom of the page to download the same Linux driver file that came with the CD, but again I'm not sure which file I should copy over to the downloads directory.
Any help would be appreciated, if you could advise the correct syntax that would be great as I'm still a novice on Linux.

Looking at that page; that's the driver you want.
Click on the orange circle with the arrow in the middle of the circle under the Linux icon.
When you do a window will open showing you this:
Code:
rtl8192cu-8188cu-linux_v2.0.939.20100726.zip
Save the file to your Dowloads folder.
To install the driver:
1. Open your Downloads folder.
2. Right click on that rtl8192cu.zip file and extract here. It will extract the script file from the folder.
3. Leaving the Downloads directory open, open the termianl and type:
Code:
cd Downloads
4. Then you'll get something like:
Code:
your name@ xxx: Downloads#
5. Right next to the (#) sign type ls and it will list everything in your Downloads folder.
6. At your your prompt type:
Code:
bash (word for word exactly the name of the driver including the .run at the end of it.
And press Enter.
7. Upon doing so the terminal should open a installer wizard for you to follow.
Follow the prompts till the installer tells you it is installed.
8. Once installed you most likely should restart your computer for it to take effect.
To make things easier you could remame the .run file. I always do.
For example I install the amd catalyst -13.12-linux x86.x86_64.zip that's to much to type at the bash prompt and it only takes one mispelling
or leave one letter out and it doesn't get installed properly. So, when I install a driver that has a long name I rename (amd.run) it like so-
Code:
Instead of $bash amd cataylast-13.12-linux x86.x86_64.run
This instead: $bash amd.run
hugh@HP-Compaq-nx6125:~/Downloads$ bash EW-7811Un_Linux_1.0.0.3.run
bash: EW-7811Un_Linux_1.0.0.3.run: No such file or directory
hugh@HP-Compaq-nx6125:~/Downloads$ bash (EW-7811Un_Linux_1.0.0.3.run

hugh@HP-Compaq-nx6125:~/Downloads$ bash$ EW-7811Un_Linux_1.0.0.3.run
No command 'bash$' found, did you mean:
Command 'bash' from package 'bash' (main)
bash$: command not found
hugh@HP-Compaq-nx6125:~/Downloads$
I tried a few times with different syntax but no joy. can you see where I went wrong?

thanks for your patience :-(

Looking at your output of your Downloads folder you have EW-7811Un_Linux_1.0.0.3.zip That is the zip file the outer shell so to speak that holds the .run file inside of that shell.
When you right clicked on the .zip did it extract the file into your Downloads directory?
Be careful with your typing. It has to be exact-
I make typing mistakes that's why I rename the file to help keep it simple.
Code:
Downloads$ bash (EW- THE LEFT PARENTHESE should not of been used
/Downloads$ bash$ EW-7 THE ($) SIGN should not have been typed
Hope that helps
Don't forget to post the output of the commands that my associate Senior Member: rokytnji; asked you for in Post #2.
The output will help him to diagnose what is going on with your system and tell us what version of the kernel you are using.
you may get message that says... "This user is not allowed to use direct links" but you can still click the link ok.
could you have a look to see if there is file in there that I can run with the bash command? is it contained in a folder further down the file structure?
Thanks for your patience, it is much appreciated, I think we are nearly there.
I went ahead and downloaded the driver and opened the zip on my system.
I now see what you have going on.
For some reason that file doesn't have an extention.
The driver is inside of the EW-7811Un_Linux_1.0.0.3 right click extract-
Than you get EW-7811Un_linux_v2.0.939.20100726.tar.gz.
Now right click here and "Open The Termianl here"
And you should get:
yourname@localhostname of driver).tar.gz$

Code:

ifconfig -a (when I returned to the file to copy and paste it the text moved separately to a second page) Sorry about that: rokytnji-
For cat /etc/resolv.conf I think the reason why the terminal returned 'no such file or directory' is because there has to be a space between the "t" in cat and the "/" forward slash.
And I opened the Ew-7811Un_Linux_1.0.003 file extracted it again and had a tar.gz.zip file. So I extracted that tar.gz.zip and found the file that is the actual driver it's self. (See in the picture where my cursor is pointing) http://s1052.photobucket.com/user/Ul...Targz.png.html
Getting to this driver was a little more complex than I thought,parker.hugh;
Sorry about that.
I had to right click open terminal here: (you will have to do the same)

Reason: Explain how to open the driver file in the terminal
