[SOLVED] usb dongle wifi access point

Adol · 04-13-2011, 10:06 AM

Hello,

I have a usb dongle wifi access point that I want to use on my linux machine to create a small network.

the model is GW-USNANO2(from PLANEX)

I think the driver it uses is rtl8192cu

Is there a way I can use this driver in OpenSuse 11.4?

I can see the usb when I run lsusb -v

I get this output:

I don't think the kernel version with SuSE 11.4 has a driver for this device.

Code:

/lib/modules/2.6.37.1-1.2-desktop/source/drivers/net> grep -i '0x2019, 0x' * -R
wireless/zd1211rw/zd_usb.c:     { USB_DEVICE(0x2019, 0x5303), .driver_info = DEVICE_ZD1211B },
wireless/ath/carl9170/usb.c:    { USB_DEVICE(0x2019, 0x5304) },
wireless/ath/ar9170/usb.c:      { USB_DEVICE(0x2019, 0x5304) },

wireless/rt2x00/rt73usb.c:      { USB_DEVICE(0x2019, 0xab50), USB_DEVICE_DATA(&rt73usb_ops) },

From your post, your device has a manid of 2019:ab2a.

Bus 002 Device 003: ID 2019:ab2a PLANEX

When I purchased my Netbook, the wireless device (atheros) wasn't supported because the model was too new. Even though I knew it would use the `ath9k' kernel module. I installed the kernel from the SuSE Factory repo, to solve my problem. Another option would have been to download a vanilla kernel, if the device is supported.

Looking further I see that there is an RTL8192U staging driver. This module is supplied by the SuSE 11.4 stock kernel: "CONFIG_RTL8192U=m"

You could try modprobing the r8192u_usb kernel module and see if the device works.

Thank you.

I found a way to get it working using a ubuntu forum.

You need to download a driver for it from realtek but the installer doesnt work. Needs to be built from source with some modifications.
