Deco W7200 - Ethernet Backhaul is slower than WiFi
I have been using the W7200 for about a year for wifi only. It's been great.
Recently, I set up a home office and ran a Cat6 ethernet line from my main router to a wall jack, and from the wall jack to my computer. I tested the connection and found that the speed from the line is significantly slower than the wifi.
Speed from ISP: 300 mbps down
Speed on Wifi: 300 mbps down
Speed on ethernet: 90 mbps down
Any ideas why the wired speed is so much slower?
To clarify the wired connection path: Modem > Router (Deco) > Cat6 line to Cat6 wall jack > Cat6 line from wall jack to computer
