So I tested it on Trisquel by making the following steps:
1. At the evening I shut down the computer, take off the Battery and the
power supply.
2. At the next day I booted Trisquel from a USB Stick and both Wifi and
Bluetooth works well.
So there cant be store anything from Ubuntu
I will test it under Trisquell at the weekend and give you an answer. Actuall
it works well under a Ubuntu system. I had in mind, that also Ubuntu would
ask when the card needs any other firmware than the ath9k?
It works perfect. So if anyone needs a better wifi and bluetooth card for
his/her Thinkpad X200 it is a great choice.
Thx, the website is very useful I ordered one of the cards and will give a
feedback when it is here.
