no wlan with Realtek RTL8191SEvA wireless lan controller

Hi.

I'm unable to get my wireless internet working. Udev doesn't load the module needed and I don't know witch one it is. I have a hunch it might be the "rtl8192e" module that should be a part of the kernel according to the wiki but I get a "FATAL //...// not found" error when modprobing for it.

Here is the output of a few relevant commands:

lspci | grep -i net

Gratefull for any help. I'm lost in long lists of modules and down to guessing randomly witch ones to modprobe for.. so far none have worked..

Did you try loading the drivers?  you can find them here i think.  http://www.realtek.com/downloads/downlo … Down=false if of course you will have to compile the drivers.   there is instructions in the file,  i never used arch came to the forms to figure out how to install,  you need packages gcc kernel-headers and make  . or there archlinux equivilants.   

Sounds stupid but do you have a button to turn your wireless on and off?  mine is above the shift key on the top row. 

try maybe ifconfig wlan0 start     

and again i dont use arch, just thought maybe i could be of some help. 

if you need help compiling the drivers let me know ill try and help  .. 

mitch.

of course you do all this as super user , su , or root whichever you call it.

Do you have the correct firmware? What does dmesg say when modprobing the module?

Re: no wlan with Realtek RTL8191SEvA wireless lan controller

mitchstarr: The link you gave is bad, it redirects to some other realtek site. And also, since the wiki says the driver should be in the kernel I feel I should be able to load it. I don't want to kompile and install a driver from somewhere else if there is support for my card already.. If however I do, eventually, need to kompile and install the drivers from realtek I will need help, thanks smile

Gusar: My system is up to date. So I should have the latest version of everything, what firmware, specificly, is it that I should check the date on?

dmesg doesn't give any new output when trying to modprobe the "trl8192e" module (since it can't find it?). I found however that when loading the "r8192e_pci" module dmesg gave this:

r8192e_pci: module is from the staging directory, the quality is unknown, you have been warned.
ieee80211_crypt: registered algorithm 'NULL'
ieee80211_crypt: registered algorithm 'TKIP'
ieee80211_crypt: registered algorithm 'CCMP'
ieee80211_crypt: registered algorithm 'WEP'

Linux kernel driver for RTL8192 based WLAN cards

This doesn't sound to good. according to the output, this is obvioulsy the correct kernel driver, only it has no effect on my card. Does that meen I have to downloand and kompile the realtek drivers, or is there another solution we can still try?
