You can try this solution

@Pilot6 Thanks, I'm trying and give feedback then

@Pilot6 The compiling failed. Here is some relevant output.

The first error says recipe for target '/.../install_folder/driver/rtl8192EU_linux_v4.2.2_7585.2‌​0130524/os_dep/linux/‌​‌​usb_intf.o' failed

I can't help at the moment. I build lots of realtek drivers to debs, but did not look into this one yet.

possible duplicate of rtl8192eu driver does not work

@Pilot6 Would give you a bounty of 100 rep points if you do it. :D

I added another solution, You can give a bounty there, if it works. And I will build a dkms package to be able to upgrade kernels.

@Pilot6 Umm... I'm getting Error! Bad return status for module build on kernel when I dpkg -i that.deb...

Well no dice then yet.

@Pilot6 It didn't really fail. Now wlan0 appears in ifconfig output but it doesn't have an address. Here is the ifconfig output.

This show Ethernet, not wlan0

Hi!

Hi

Click on show more.

I do not see wlan0 there

I'm posting it here:

What is in your /etc/network/interfaces

$ cat  /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

# Wifi
auto wlan0
iface wlan0 inet dhcp
        wpa-ssid "Edimax"
        wpa-psk "ghi.....4"

@Pilot6 I added # Wifi stuff manually, from a previous try

without quotes

If you do not, then you have to start it

ifup wlan0

But I need the eth0, otherwise I lose the internet connection.

one or another

(right now I'm using eth)

Is ifup wlan0 supposed to work with the current config?

I'm happy to start it manually

Why do you need to setup them manually. You can setup both in NM

How can I check if network manager is installed?

If I write sudo service network-m<tab> no autocompletion

It is always installed, if you did not remove it

But it autocompletes for service networking

I'm running Ubuntu Server

OK. Then

ifup wlan0

ifconfig

$ sudo ifup wlan0
[sudo] password for ionicabizau:
ifup: interface wlan0 already configured

Should I ifdown it first?

you can try

And now it hangs:

$ sudo ifdown wlan0

Maybe some wrong config in interfaces

I don't have the network-manager installed... Maybe should I install it?

You can install it and use nmcli. or look how correctly setup it manually

@Pilot6 Now I'm getting this ^

@IonicăBizău It is good

You got the address

@Pilot6 Oh, didn't realize that.

@Pilot6 Now I'm getting /sbin/wpa_supplicant daemon failed to start
