Review on Enhance Your Wireless Range with TECHTOO Dual Band WiFi Antenna (2-Pack) - Compatible with Router, Adapter, IP Camera, Drone & More by Terry Moore

I've read where people said these antennas don't work. So I decided to test them. My main problem is connecting to two Foscam R2 cameras. I record videos to SD card at night and copy/transfer videos to my server in the morning. I have an ASUS RT-AC66U router configured as an access point that cameras connect to. The camera farther from the router had a DBM -53 {about 20-22 feet through the wall}. The second chamber had a DBM -51 {about 22-25 feet through the glass window, so better than DBM}. The transfer rate of both cameras was too low at around 600-650 Mbps. I once installed 3 of these antennas on the RT. -AC66U DBM for the camera through the wall was -47 and through the glass -45. The transmission speed has been increased to 1.85-1.90 Mbps. The best speed I've ever had with a FOSCAM R2 camera with DBM-32 is 2.1Mbps. So these antennas nearly tripled my baud rate and increased my DBM by -6. You're worth it.
