Have some sticks tried to solve the following problem: On my WD Live Hub (player for avi, mpeg etc videos and pictures) I can connect USB WLAN sticks. So I bought several sticks with different versions. Result was functioned none of the purchased WLAN sticks with this player, they were simply not recognized. Also the Samsung Player did not recognize these foreign Sticks. However, the Samsung Bluerayplayer enclosed WLAN Stick worked on Player WD Live Hub.
So selling all other sticks and bought this WLAN stick original Samsung. This was immediately recognized by all DEVICES AND has a data transfer rate of 5 GHz frequency and 300Mbit of effective 7-8 megabytes / second.
