how to install netis WF2123 USB WiFi on Ubuntu 16.04.2 LTS x64?

Question

I can not use the "netis Wf2123" adapter (http://www.netis-systems.com/Suppory/de_details/id/1/de/89.html).

My Operating System:

Cat / etc / lsb-release
DISTRIB_ID = Ubuntu
DISTRIB_RELEASE = 16.04
DISTRIB_CODENAME = xenial
DISTRIB_DESCRIPTION = "Ubuntu 16.04.2 LTS"

Uname -a
Linux KB4051 4.4.0-79-generic # 100-Ubuntu SMP Wed May 17 19:58:14 UTC 2017 x86_64 x86_64 x86_64 GNU / Linux

The driver to the device downloaded from the manufacturer's website "netis WF2123 Driver for Linux, 2017-02-21"  

At compilation I receive the following message:

how to fix ?

I am a beginner, when replying, please provide more details.

Answer 1

This driver needs to be patched. I have a rtl8192EU in my PPA with a patch, but it does not have your device. I can't add it now.

You can fix it yourself.

Open Makefile in the driver directory and add there

EXTRA_CFLAGS += -Wno-date-time

after the existing EXTRA_CFLAGS lines. This will sort out the build problem.
