Just installed two Deco x68s, and I'm very happy with the wifi speed and coverage. I've tried everything I know to do, but a speed test reveals download speeds of 50-60 with my device (AppleTV) wired directly to the Main Deco, while via WIFI, I'm getting 500mps plus. I've tried switching out cables, and clearing high priority devices. Any suggestions would be greatly appreciated. ISP is xfinity, and I pay for 500mps. Thank you in advance.
