Hi David, your modem levels look quite nice. I'm not seeing any packet loss, timeouts, or noise. Are you able to provide results of a hard-wired (not WiFi) speed test for us? I'd like to see what download and upload speeds you're receiving. Also, is this happening on the 2.4 GHz, 5 GHz networks or both?
The 2.4 GHz band offers better Wifi coverage, but is prone to more congestion due to heavy network traffic. The 5 GHz band offers less range, but delivers faster speeds thanks to less congestion and wider channels. Here is some additional information on ways to improve your WiFi service:

If your download and upload speeds are within the normal range, then you may be experiencing WiFi interference. -Kevin M. Cox Support Forum Moderator
