After I installed the stick and put into operation, the disillusionment came. Although my router Fritz WLAN 3170 had about 3 feet line of sight, was the reception: constant low to schlecht.Selten sufficient. The scrap swapped back to: TP-Link 150 Mbps USB Adapter. (TL-WN722N) - Reception: Without exception, very good to excellent. That's it!
