Bug 582168 – net-wireless/rtl8192eu - ebuild request for Realtek 8192eu 3rd party driver

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Nicola Sensini 2016-05-05 15:42:18 UTC]

I would love to have an ebuild for this wireless module that isn't in kernel (even staging), yet (as of linux 4.5.3).

You can download the driver (working for 4.5.3) here:

https://github.com/donahue95/rtl8192eu-linux-driver

Just cd into the dir, then make && make install will create a 8192eu.ko module for the current running kernel.

This is probably obsolete with the kernel's rtl8xxxu which includes support for 8192eu

[Comment 3 Nicola Sensini 2016-05-05 16:25:51 UTC]

rtl8xxxu.ko doesn't work for my 8192eu card (0bda:818b).

It was temporarily disabled. [1]  In the future, the support will be there.

The fact is that the kernel module does not work with all rtl8192eu chips, in kernel sources there is no their VID / PID, and if you add them manually, the adapter starts to see the network, but cannot connect to them, unlike the third-party driver.

Here is a link to the kernel bugtracker with the problem https://bugzilla.kernel.org/show_bug.cgi?id=196769
