Hello,

I would like to get the title wlan n usb card to work in my 3.7.10 gentoo on IBM x41, however i fail to find the proper driver for it. What is reported in the system is:
Code:

x41 ~ # lsusb
Bus 001 Device 005: ID 12d1:1436 Huawei Technologies Co., Ltd. E173 3G Modem (modem-mode)
Bus 001 Device 002: ID 0bda:8179 Realtek Semiconductor Corp.
Bus 004 Device 002: ID 0483:2016 SGS Thomson Microelectronics Fingerprint Reader
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


And in dmesg:

Code:

Mar 23 08:51:31 x41 kernel: [    2.435479] usb 1-4: default language 0x0409
Mar 23 08:51:31 x41 kernel: [    2.435850] usb 1-4: udev 2, busnum 1, minor = 1

Mar 23 08:51:31 x41 kernel: [    2.445968] usbip-host 1-4:1.0: 1-4 is not in match_busid table... skip!


I just get info that:
Code:

[    2.111243] usbcore: registered new interface driver ums-realtek
[    2.441637] usb 1-4: Manufacturer: Realtek


The iwconfig gives just:

Code:

wwan0     no wireless extensions.


(btw. the other atheros card in this notebook works fine already)

I have emerged the linux-firmware, and i am trying some realtek .bins during the kernel configuration but so far they do not work. From the Wireless device drivers section i also compiled all Realtek drivers into the kernel (should they be compiled as modules?). Please advice on the driver that would fit this card, since co far the activty LED doesn't even blink or the course of action to undertake...or probably could You please suggest a troubleshooting method this linux-firmware testing...

Regards,
stolar

rtl8188eu is the driver for this thing, it's available here: https://github.com/Red54/linux-shumeipai2/tree/sunxi-3.0/drivers/net/wireless/rtl8188eu. You'll have to copy it into the kernel source tree and adjust some Makefiles. Just google for 0bda:8179, you'll find lots of info.

Gusar thank You for the reply,

however i fail to see such driver under /lib/firmware...(although the linux-firmware package was updated yesterday).
Could You give a brief general plan on how to adopt the files from the link You gave so that the driver works in gentoo system?

Hello,
I have same TL-WN725N adapter and lsusb shows:
Code:
#lsusb
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 005: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

Try compile module for RTL8188CUS which you can find in Device Drivers>Network Devices>Wireless LAN.
[M] Realtek RTL8192CU/RTL8188CU USB Wireless Network Adapter

Adapter works, but still I have problems to configure it with wicd...:-/

Regards,
Filip

philipo, you have a different device. Yours is 0bda:8176, stolar's is 0bda:8179. That's why I always say marketing names are meaningless, only the pci-id (or in this case, the usb-id) matters.

There's a new driver available that might handle the 8179: http://www.spinics.net/lists/linux-wireless/msg105579.html
