Wifi card not detected with ifconfig (solved)

Hello,

I'm not sure wether I should post this here or not...

However, I'm using a Realtek Wifi card RTL8188CE on my laptop and I couldn't succeed in using it. (I'm using Arch x64, it's up-to-date).

I tried using ndiswrapper, but even when the ndiswrapper module is loaded and the driver properly created from the ".inf" file, ifconfig -a still doesn't display anything else than the usual "eth0" and "lo".

Here are the information I think are useful, please tell me if I forgot anything.

I have the same problem, but withe broadcom wireless card. Have you read this wiki page Wireless Setup? It's helped me to get 'wlan0' in the output of 'ifconfig -a' but I still cann't use it too

Re: Wifi card not detected with ifconfig (solved)

Hello,

I finally solved my problem. It turns out my driver existed on the AUR and all I had to do is load the corresponding module with modprobe.

Some useful links :
https://wiki.archlinux.org/index.php/Wi … _Supported
https://wiki.archlinux.org/index.php/Co … ice_module

Also here is the very same topic on the french forum where I was helped solving my problem (hopefully google is gonna be able to translate it) :
