RTL8188CUS firmware trouble

I just bought a couple of 802.11n USB dongles, and the driver installation is proving troublesome.

lsusb informs me the chipset is rtl8188cus, and the Realtek site provides this driver for it: http://www.realtek.com.tw/downloads/dow … loads=true

Running the install script works until it gets to os_dep directory.

Re: RTL8188CUS firmware trouble

I think you may open makefile and find description for building file osdep_service.c
or
open osdep_service.c at nano/vim and find line number 305 ‘init_MUTEX’ (what's wrong in implicit declarayion)

Re: RTL8188CUS firmware trouble

Aye, was hoping to avoid crawling through the source, but if it comes to that...

But interestingly, it installs and runs fine on my EeePC. Both are running basically the same Arch setup. I'll try it again.

The EeePC is running kernel 2.6.36 while the desktop is 2.6.37. Could that perhaps be part of the issue?

Re: RTL8188CUS firmware trouble

Can you rollback your desktop to the kernel 2.6.36?
If the issue is not detected, it means drivers do not support the version of the kernel.

Re: RTL8188CUS firmware trouble

You can check this thread. It is the same chipset.
