Your wireless NIC won’t activate while your wired nic is plugged in.

This thread may be applicable. I’m not sure if it’s still necessary to compile your own driver, but they had to here.

Please post the output of


/sbin/lspci -nnk | grep Realtek

With the PCI IDs in this output, we will be able to tell what device you have. I
think it will use a new driver that I just received from Realtek and plan to put
into the 2.6.39 kernel.

Thank You. Since wireless nic is not working I connect with wired.

Any suggestions how to upgrade to kernel 2.6.39 from 2.6.34? Any patch available or need to build the kernel?

I managed to found the driver but make is giving problem.

panneer@linux-sjsw:~/Documents/rtl8192se_linux_2.6.0019.1207.2010> make
make: *** /lib/modules/2.6.34-12-desktop/build: No such file or directory. Stop.
make: *** [all] Error 2

Kernel 2.6.39 is in the future - 2.6.38 is at rc3.

The build error happens because you have not installed the kernel headers. They
will be at <some path>/include/… and /lib/modules/2.6.34-12-desktop/build
should be a link pointing at the correct value of <some path>.

I have not tried the driver from the Realtek web site; however, my experience is
that those drivers will work for 32-bit systems, but not for 64-bit versions.
The one I’m working on came from Realtek by private means.
