kind of led me to that: TP-Link TL-WN722N WLAN USB Adapter Stick 150Mbit 4dBi
lead me to reconsider… so i checked out:
but i could not find any wifi adapter using that dragon pendrive chipset… so checked out the broadcom chipset and:
so i was looking for Broadcom 4320 based adapters.
what works for raspberry should work for any other linux.
but it is sold out under amazon.de
but it listed this as an alternative: https://www.amazon.de/EDIMAX-EW-7811UN-Wireless-Adapter-IEEE802-11b/
which is said to be RaspBerry compatible too… ! 🙂 and the driver is said to be integrated in x>Kernel v.2.6.39
BUT! (OF COURSE) It has no LARGE Antenna… so how can it possibly pick a signal from a far away accesspoint? it can not.
So we need something with an proper Antenna…
Seems to be the winner of the game… it is said to be working „out of the box“ with raspberry pi, which sounds good.
it is named:
CSL 300 Mbit/s WLAN Stick USB 2.0 N-Draft-Wireless-N-LAN-Adapter-Mini-Dongle with external Antenna
0f:00.0 Ethernet controller : Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 07)
Works out of the box.
for me: not really. it works. sometimes.

Kernel driver in use: r8169
Installing the best driver
using the „official non free debian apt get repo binaries“ for this adapter seems to be a bad idea.
it installs the wrong version? (8712u.bin instead of 8168)
Linux debian 3.16.0-4-686-pae #1 SMP Debian 3.16.7-ckt25-2+deb8u3 (2016-07-02) i686 GNU/Linux
dmesg | grep warned;
[ 152.367245] r8712u: module is from the staging directory, the quality is unknown, you have been warned.
[ 152.689345] usb 2-1: r8712u: Loading firmware from "rtlwifi/rtl8712u.bin"
for some reason kernel is loading firmware: „rtlwifi/rtl8712u.bin“ which does not really seem to be the right version.
Fuck the Drivers-CD:
these are the drivers that came with the driver-cd which you can download here: (of course i would be happy if free drivers become available and things really start to work out of the box)
documentation on how to compile:
this documentation is actually wrong… after unpacking the driver you should not use ./make but just make to start the compilation process… which ends (for me no matter as root or not) in an error, that i can not debug.

Download „official realtek“ drivers or: So what drivers do work?
you can download 8168 drivers sources for compilation from here:
mirror download: r8168-8-042-00-tar.gz
and tried to compile them, which actually worked.
Linux debian 3.16.0-4-686-pae #1 SMP Debian 3.16.36-1+deb8u1 (2016-09-03) i686 GNU/Linux
# you might need to get the kernel sources ( i did not )
apt-get install linux-headers-$(uname -r);
mkdir -p /software/drivers;

Check old driver and unload it.
Build the module and install
rename r8169.ko to r8169.bak
