Yes, the WaveFocus wireless USB adapter enables 2.4 GHZ wireless B, G or N connectivity for any AzBox HD receiver that does not already have built-in wireless which includes the AzBox miniMe American Edition.
The WET610N will also work with the miniMe as it is a wireless Ethernet bridge. You could also use a pair of powerline Ethernet adapters and avoid using wireless completely.
However unlike the WaveFocus wireless USB adapter, you won't be able to scan for and configure your wireless network via the receiver's GUI.
