Install / use of TP-Link - TL-2 notebook WN7200ND on:
. DELL Windows XP Pro SP3 required the installation of the driver (only install the driver manually not control the software that goes with it).
. ASUS under Windows7 (I do not know what family edition) was recognized without having to install the driver.
. internal antenna deactivated during the use of the outer adapter.
The original antenna was replaced by a TP-Link - TL-ANT2408CL more powerful.
All done its job well, the flow 150Mpbs allows a comfortable surfing, and no problem with FreeWifi spots or SFr Public Wifi 802.11n and 802.11g (other ISPs untested).
