Hi, i bought an alfa wifi adapter with realtek rtl8187 moderboard, when i plug it to computer using 10 meters usb cable it show me the message: usb device not recognized. but it appear on Device manager and wifi management softwares (but no wifis shown) .
but when i plug it to other cables (5meters and lower) it work without problems .
