+===== What are the advantages of WLN-M over a conventional WLAN USB stick? =====
+  * The M.2 card sits in the case and is better protected from tampering and theft.
+  * The integrated solution is more appealing.
+  * For the best possible efficiency the antenna should be at least 6cm long (half a wavelength at 2.4 GHz) which is a big advantage over the USB stick.
+  * This WLAN card is a Combo card which supports both WLAN and Bluetooth.
+  * The transmission protocol of the PCI-Express interface is less complex as compared to USB which helps keep processor load lower.
