I have a 400Mbps (download) internet speed which I have confirmed by connecting my modem directly to my computer without a router in between. This was confirmed with a speed test (Photo of 400Mbps speed test connected directly to modem).
When the router is connected I am getting a maximum download of 100Mbps over WIFI and Ethernet. When I check the Wi-Fi status of my connection on Windows 10 it is showing between 460Mbps to 866Mbps (Photo Here). However, when I run a speed test through LAN or WAN (both wired and wireless) it is giving a max download speed of 100Mbps (Photo Here). I know the router is the issue because the speed tests are throttled to 100Mbps on multiple devices.
My router is a Netgear R6080 AC1000 Dual Band WiFi Router (Link to spec sheet). It is advertising WiFi speeds up to 300+700Mbps. It has five 10/100Mbps (1 WAN and 4 LAN) Fast Ethernet ports which indicate a 100Mbps limitation over Ethernet. But shouldn't the WiFi be able to handle speeds up to 400Mbps? I am unsure if my router is throttling my connection or if I haven't set it up correctly.
