Use a slower Wi-Fi AC setting to improve stability and reduce interference.
Your D-Link DIR-859 is delivering a solid 500Mbps over Ethernet, yet Wi-Fi only reaches 30Mbps. With your router's 1300Mbps in 5GHz and your MacBook Air at 1200Mbps, the numbers seem reasonable for ideal conditions. However, you're still missing out on higher speeds. This could be due to interference, channel congestion, or signal limitations. Try switching to a different Wi-Fi channel, using a wired connection for better stability, or checking for nearby devices that might be causing interference. Resetting the router isn't the only fix—optimizing your setup might help.
Review the video to refine your expectations. The figures you mentioned are intended for promotional use, not actual performance. Conduct a wireless scan with WiFiman (mobile) or WiFi Analyzer (mobile or PC), and share screenshots of both 2.4GHz and 5GHz bands. Note the SSID you're connected to. Capture the wireless settings on the DIR-859 device and omit any password details.
