Hi,

I have an RTL8191SU (USB Wlan) adapter in my pc and I am not getting it to work (I can only see it in lsusb). I downloaded the driver from the Realtek website and it compiles without problems - but it freezes my PC a few seconds after modprobing it. The kernel version does not matter, I have tried them all from 2.6.32 up to 2.6.36.

So my question is: Did anyone here got an 8191SU NIC working on gentoo?

Thanks in advance!

Do not use the driver from the Realtek website, unless you have no other choice.

You will find a driver for the rtl8192su in the staging section of the kernel config. Press / in menuconfig to search if you can't find it. Enable that and completely remove the realtek driver. (Important: including the kernel module which it installed!)

Sorry to renew this old thread.

I have problems getting the rtl8191su to work with gentoo-sources-3.3.0. I've tried to include all Realtek wireless drivers - none gets loaded automatically. I tried adding the usb-id to the rtl8192cu driver, but dmesg shows something like "unable to load firmware" (I'm posting from a secondary OS right now...)

Is there a way to extract this firmware from the windows drivers and somehow get it to be used by the kernel module?

EDID: p.s.: ~amd64

Any help is very appreciated,
Stefan

Just install the linux-firmware package.

What does "lsusb" say about your wireless device?

Thanks for the replies so far. I'm on my laptop now (as the "updated" workstation is running windows right now for faster NTFS access).
Code:

St0fFTablet linux # dmesg
usb 1-3: USB disconnect, device number 3
usb 2-1: new high-speed USB device number 2 using ehci_hcd
usb 2-1: New USB device found, idVendor=0bda, idProduct=8172

I just found the staging drivers. Testing now on my laptop (amd64 stable, gentoo-sources-3.2.12).

The oops happened when I pulled out the WLAN-Stick from USB.

As I couldn't find the firmware blob, I searched and found net-wireless/rtl8192su-firmware - may that be the key?

No, only linux-firmware as Gusar said.

The r8172u driver in kernel 3.2 has issues. Use the 3.3 kernel.

Thank you both very much. I'll try and report back as soon as possible. (There are 1.5TB left to be copied)

backreport...

the 3.3.4 driver from staging works well, it should get noted inside the Kconfig-Help that one needs the linux-firmware package.

Thank you very much for the help. I really appreciate your help.

Cheers,
Stefan
