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, Lee Maou Sheng Software Engineer Archer Logic (S) Pte.

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.
