I didn't argue with the support rep—I understand they follow scripts and many of them are also probably dealing with at least a dozen entitled jerks per shift, so I try to be extra patient when I get to an actual human (though the chatbot tries everything in its power to rile up someone before they can get to the human!). My response to his mentioning of switching WiFi channels was more or less "I am not using the WiFi on the router, but rather the wired Ethernet port, so is there any way you can check on the bandwidth through the device itself?" (knowing that another part of the script is to run the bandwidth test on the device remotely—the previous support rep did that as well, confirming the 8 Mbps result).
