Although the Linux Kernel and the OS is supporting thousands of devices, it is still necessary to check compatibility of some devices named WLAN, UMTS/3G, Webcam, .....
So my advice for everybody: BEFORE buying check some compatabily lists!
So windy_miller, You are doing it right!
The community of Ubuntu is huge and strong ans thus it´s always woth a view to our neighbours.
If something is running out of the box on ubuntu it is almost certainly that the device is also running under Pardus.
My experience ist that Ubuntu does not work too much on the kernel so if the device driver is in the kernel, and Pardus is using the same kernel, then it should run.
My advice for Network-Devices is to always use/buy Atheros chipsets!
Until 2008 Luis R. Rodriguez is payed by Atheros for developing Linux drivers. Mr. Rodriguez was formerly developing the MadWifi-Driver. MadWifi was also a driver for Atheros devices, but it was not free because he was using proprietary code.
Atheros Drivers You can find already in the Kernel: http://wireless.kernel.org/en/users/Drivers/ath9k#supportedchips
Here is a compatibility list of network-devices of ubuntu:https://help.ubuntu.com/community/WifiDocs/WirelessCardsSupported
Have a closer look to the vendors Realtek and TP-Link!
