Slow wifi download speed archer C59
A week ago, I upgraded my comcast xfinity internet service to 200 mbps download speed, but i have not been able to see any improvement in speed through the archer C59 router.
When connecting the modem directly to my toshiba laptop, speedtest.net shows 240 mbps download speed. Contacting tp-link.com live chat was not helpfull. I have already reset my router a couple times without any change. My laptop, router and modem are all within one foot of each other. Below are some screen captures I took for tp-link.com tech support.
Help please.
