Review on Eightwood 2.4GHz 5GHz 5.8GHz Dual Band WiFi Antenna 5dBi RP-SMA Antenna (2-Pack) for PC 🔗 Desktop, WiFi Router, PCIe Network Card, USB Adapter, Wireless Range Extender, IP Camera: Enhanced Wireless Connectivity Solutions by Shawn Torres

Used as a replacement for the Intel Square Antenna AC-7260 Wi-Fi Desktop Card/Mounting Bracket. The computer is in the same room as the router and without an antenna I was able to pull down 80 Mbps and push 20. With those antennas installed, it was 35 down and 20 up. This is on the 5GHz channel with minimal interference. The antennas were carefully installed and positioned so that they did not touch the cables or anything else. From this I can only conclude that they are garbage - at least for my application. I've been using it for a few days, getting consistently slow speedtest.net results, and running the test a couple of times right before/after uninstalling, and noticed an immediate improvement in speed.
