Review on SilverStone Technology PCIe WiFi/Bluetooth Adapter With Two Dual Band MIMO Antenna (Requires Additional WiFi / Bluetooth Module) ECWA2-LITE by Brandon Frogge

I was hoping for a slightly stronger signal by replacing the stock antennas on my Linksys EA 6900 router. Using the RE7000 expander's built-in diagnostics, no signal improvement was measured at the expander despite the large signal improvement at the larger size . So for me it was of no benefit. I'm not sure under what conditions this would happen or if the active electronics would somehow need to detect a different antenna, but at least the Linksys EA6900 either already had better antennas or didn't know what to do with them.
