Short and sweet: Operates in the 2.4 GHz and 5 GHz without complaint. Operate in the 5 GHz band to my main line to relieve him at 2.4 Gz. Setup and configuration running without any complaints. I had ordered me two of them: one for a window PC as a media center, the second wireless stitch runs on Linux (Ubuntu and Knoppix) natively. In beidne operating systems no restrictions in operation. In addition to the Stick is also an extra in a USB extension if the PC "radio technology" is not good - you can then throw the stick and does not have to dislocate the whole PC. Preis-Leistung TOP
