Hi Larry,

Thank you for the reply. Our clone image standardized for all outlets for
the convenience of maintenance but somehow we have client would like to do
on wireless instead of wired. I am very appreciate if you are able to build
on that kernel.

Thank you very much!

Best Regards,

Hi sir,

I am from Singapore and currently our company is trying to install

WN2001 wireless adapter into Dell PowerEdge T20 with Centos 6.6

driver.

That device is not an RTL8192SU. It is an RTL8188EU, which has a driver at
http://github.com/lwfinger/rtl8188eu.git; however, that version probably
will not build on a kernel as old as 2.6.32. I try to allow a build for
kernels as old as 3.0, but yours is quite a bit older.

Is there any reason that you cannot upgrade to a newer kernel? The driver
you need was added to the kernel in 3.19.
