Review of Linux Compatibility
The ZyXEL NWD2205 is a very small USB WiFi adapter with the USB ID 0586:341f:
Bus 001 Device 004: ID 0586:341f ZyXEL Communications Corp. NWD2205 802.11n Wireless N Adapter [Realtek RTL8192CU]
The stick bases on the Realtek RTL8192CU chipset, which is supported under Linux by the rtl819x kernel module (e.g. since Ubuntu 12.10).
Alternatively, under older kernel version (up to version 3.4) the original Realtek driver can be used. This driver can be downloaded from the Realtek homepage.
The Realtek driver needs to be compiled and installed per hand. The installation script, which is included in the downloaded packages will take care of this (it is possible that the script needs to be changed to an executable file firs):
chmod a+x install.sh ./install.sh"
To suppress the automatic loading of the kernel module rtl8192cu from the standard Linux kernel if the Realtrek driver should be used instead, one has to list the rtl8192cu in one of the blacklist files at /etc/modprobe.d. The following lines have to be added:
#blacklist realtek wireless n drivers for Zyxel nwd2205 blacklist rtl8192cu
