Problem : Realtek Wi-Fi card : unable to detect a network

Hello world,

I moved from 2.0 to SliTaz 3.0 quite recently, and now I've returned to my real (professional) computer I realized that my network device seems to be undetected. I explain : following the handbook and using all the debugging commands I'm still unable to access my wifi. Either on wlan0, eth0 or lo, either with the key or not, either with the ESSID or not.

lspci | grep -1 network returns :

"0e:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8172 (rev 10)"

dmesg | tail returns 10 errors :

"ACPI Error (evevent-0306): No installed handler for fixed event [00000000] [20090320]"

While testing, I loaded ALL the modules and installed ALL the firmwares (but I doubt it worked, cause without wifi I can't access the Internet). No result.

lwconfig returns "no wireless extension" for both lo, dummy0 and eth0. Even after changing modules or restart. I noticed in the shell : "wlan0    No such device", "wlan0 is not a wifi interface, changing it. Configuring ... ifconfig : up: error fetching interface information: Device not found".

If needed, I have some screenshot I'll be able to post.

Could you help me fix that problem ? Thank you.

P-S : excuse for my bad english, I'm french but I prefer post that topic in the english section, cause it's more used and answered.

Just tried. Instead or eth0 or wlan0, right ?

Doesn't change anything.

(I didnt knew this interface exists, anyway)
