Title: wifi TL-WN725N
Post by: Lukas Mistr on December 22, 2014, 03:38:04 pm
good day

I would use wifi TL-WN725N that uses rtl8188eu. I use Linux Kernel 2.6.35. Could you advise me.

from the original version 2.6.35-8-ARCH I switched to 3.12.0-rc3-dirty, and I tried these instructions

But I failed but I received this message

The Linux kernel contains data structures whose layout varies not only from version to version but also depending on the compilation options. The message you get says that the version check fails during load of the module.
You may google CONFIG_MODVERSIONS to get an idea how the version check works.

I assume you downloaded the kernel and not build it yourself, right?

How about starting to build the kernel yourself by following Christians blog post and then building the drivers using the same kernel headers?

I have solved the problem.

it is necessary to modify the kernel for example by site

In menuconfig, you need to add drivers for the wifi. Now the drivers are not fully debugged and therefore is in

devices drivers / staging drivers
