EW7811Un USB wireless card - can't install driver!
« on: December 12, 2011, 10:32:02 AM »
Hi, I know this topic has already been covered at http://www.pclinuxos.com/forum/index.php/topic,92694.0.html
but it couldn't answer my problem:

I've uploaded pics of the make, post-make commands, and also some diagnostic information. When I tried to run cat /etc/sysconfig/network-scripts/ifcfg-wlan0, ifcfg-wlan0 didn't exist.
See the pics here:

(Updated from a photobucket link in response to djohnston's post below)

And using uname -r gives kernel version: 2.6.38.8-pclos3.bfs
I'm using XFCE.

I've attached the usb nic and tried to install the driver. The one which came on CD is the same as the latest one on the website, as I tried both and they were named the same.

Following the instructions provided with the driver I decompressed a .tar.gz then used the 'make' command which ran ok but threw up two errors. Following the instructions I tried a ./clean which couldn't find modules to clean, and then finally I tried a insmod command which didn't work either. These instructions say they are based on using fedora, not sure how much the commands would differ.

I'm a complete noob when it comes to adding new hardware in linux, the diagnostic information came from the networking forum starter tips, I would never have known them otherwise.

Thanks, Martin

Hi Martin

First of all, I would try to avoid installing from source unless you kno exactly what you are doing - it can be a bit difficult and the stability of PCLOS comes from sticking to the programs in the repository.

I had a look at your pics and the "driver" failed to build - which accounts for you not seeing it when you ran insmod. The "error" messages mean that the build has failed.

I haven't had a look at your earlier thread as yet, but will do so in a moment.
The Realtek modules are mostly included in the kernel these days, so I am surprised that yours is not - but I do know that some are not.

Will take a look at your other thread. I could guide you through compiling from a source package if you get really stuck, but would need more info to do that and, until we know for sure there isn't a module already in the kernel, it is best to hang fire...

Okies, had a quick look at the other thread and the advice given by muungwana would be the best option - i.e ask for one of the folks here to package this for PCLOS.

If you really wish to pursue building the "driver" from source, then could you give the location you got the file from and perhaps we can sort it.

Have you tried the rtl8192SE driver in the repos?  No idea if it will work, but worth a go I suspect. Note that you will need both the dkms-r8192se file and presumably the associated firmware rtl8192se-firmware.

Hi kernowyon and djohnston,

Thanks for the replies.
Okies, had a quick look at the other thread and the advice given by muungwana would be the best option - i.e ask for one of the folks here to package this for PCLOS.

kernowyon, I've taken your advice and created a package request thread http://www.pclinuxos.com/forum/index.php/topic,100635.0.html as per muungwana's post.

I also tried the rtl8192SE driver, but I ran into problems trying to install it, see picture here:

djohnston, I've changed the location of my images after your advice and updated my original post, I didn't realise photobucket is a bad egg, thanks for letting me know.

Martin,

The dependency issue you have there with Synaptic and dkms sounds as though you need to update your package list. Of course, you may have done that already - in which case the problem may lie elsewhere, but I would try updating your Synaptic with Reload, Mark All Upgrades, Apply.

Once that has completed, then try installing those packages again. It may be the case that they don't work for you, but worth a go.

Hopefully someone will get the drivers packaged up for you soon.

kernowyon,

I updated synaptic as suggested with Reload, Mark All Upgrades then applied them all, then tried to install the rtl8192SE driver again but I got the same error as before. It seems that they won't work for me, but at least now I know. I will wait for the drivers to be packaged.

Many thanks, Martin
