Despite having ordered two evo-w54pciv2 cards (order confirmation under the eyes) I received (sender Mecer) evo-w542Pci two cards. The difference is important because the received models do not possess the antenna with extension wire 1m. I tested them with two kinds of antenna and to a PC located one floor above the box, one passes a very good signal (with the thread) to a weak signal and thus very slow with the received antennas .
Recognize that the little difference between the reference and one reference the other can explain part of the delivery error but, when pressed, that's galley
