Wifi doesn't works

Hello,

I have a big problem with my Wifi because it doesn't work.
My chipset is a Realtek 8192e so I installed the firmware thanks to AUR : [wiki]http://aur.archlinux.org/packages.php?ID=36675[/wiki]
and I launch : modprobe rtl8192e_pci

03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8192 (rev 01)
PCI ID : 10ec8192

After to configure my Wifi, i follow this page :
[wiki]http://wiki.archlinux.org/index.php/WPA_Supplicant[/wiki]

But i have a problem when i launch wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf
I have these two lines :

ioctl[SIOCSIWPMKSA]: Invalid argument
ioctl[SIOCSIWPMKSA]: Invalid argument

So my wireless device is not associated with my router and i have a timeout after to launch dhcpcd wlan0.
But i find my router when i launch ifconfig wlan scan.

I don't understand because my Wifi works correctly on Debian Sid.
Thanks for your help.

Do you have wireless_tools installed?

Please fix the link to the firmware you got from AUR.

Re: Wifi doesn't works

Was there no output from modprobe?

The name of the kernel module for the rtl8192se chips is actually r8192se_pci, not rtl8192se_pci.

So, after you install the wifi driver, try:

modprobe r8192se_pci

then bring up the interface and launch wpa_supplicant.

Re: Wifi doesn't works

@karol : Yes, I installed wireless-tools during the installation of Archlinux (Core Image)
For the firmware on AUR, it's here : http://aur.archlinux.org/packages.php?ID=36675

@Alexandrite, i've not 8192se but 8192e chipset and I made an error by writing, i launched r8192e_pci not rtl8192e_pci.

Yeah, I know that, but your link in the first post points to nowhere - click it and see for yourself.

Follow alexandrite's advice and modprobe the module you have: 'modprobe r8192e_pci'.

Re: Wifi doesn't works

What does 'ifconfig -a' show - are you sure wlan0 is your interface?
Did you check the logs? Maybe there's sth interesting there.

Re: Wifi doesn't works

When i launch iwconfig -a, i have this :

eth0      Link encap:Ethernet  HWaddr 00:24:54:5F:EE:33  
          inet addr:192.168.2.6  Bcast:192.168.2.255  Mask:255.255.255.0

          RX bytes:342 (342.0 b)  TX bytes:583 (583.0 b)
          Interrupt:19 

wlan0     Link encap:Ethernet  HWaddr 00:E0:4C:00:00:01

          Interrupt:16 Memory:f8448000-f8448100

For eth0, it's the same MAC Adress on Windows 7 (ipconfig -all in cmd).
For wlan0, it's not the same MAC Adress when i see on Windows Seven.

But i have this same MAC Adress on Debian (HWaddr 00:E0:4C:00:00:01 ) and the wifi works correctly.
Strange....

Re: Wifi doesn't works

Sorry karol, but the method2 doesn't work ( I haven't Wake-On-Lan After Shutdown) and in the BIOS, it's already "Enabled"...

Re: Wifi doesn't works

Hello,

I re-installed Archlinux and i did the update (update to 2.6.34 for example) and i configure my wifi like in this page :
http://wiki.archlinux.org/index.php/WPA_Supplicant

So, i generate a new wpa_supplicant.conf tkanks to this command :

wpa_passphrase mywireless "secretpassphrase" > /etc/wpa_supplicant.conf

My network is recognized when i launch :

iwlist wlan0 scan

So, i launch now this command :

wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf

And this is my result :

CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
Trying to associate with 00:1c:df:3f:dc:63 (SSID='******' freq=2412 MHz)

It's always in continue so i did ctrl+c to stop it.

Re: Wifi doesn't works

There was a topic about the four-way handshake failing, I'll try to find it.

Have you already tried http://wiki.archlinux.org/index.php/WPA … leshooting ?
Edit: https://bbs.archlinux.org/viewtopic.php?id=93271 - downgrading the kernel worked for many people
