Nighthawk XR500 - slowing my speeds down

Question

So I have Cox Gigablast. Speedtest from modem directly to PC I was getting 750 download and 35 upload. When I connect through my XR500, the download speeds plumit down to 90 while the upload only slightly decreases to about 20.

I've looked online at various guides/settings and geez, I can't figure out why I am getting such a huge hit on my speeds. I have no kids, just me and my GF and she hardly even uses a computer or phone so there's no huge allocation to other devices. I am hard wired into my router from my deskopt PC. I've double checked to make sure cables are all newer and in good shape. Cox service tech came out and tested from modem and was getting 900 download.

Please, somebody help me get these speeds up. Nothing worse than paying top dollar for high speeds and not getting anything close to them. Thanks.

Thank you so much. That definitely was the problem. Now my download speed is 760 and my upload is 35.&nbsp;Netduma-Fraser&nbsp;wrote:Thanks for the screenshot. The ethernet cable connecting your XR router to the modem is only capable of 100Mbits, you will need to use an ethernet cable that is at least Cat5e, you need another one for the ethernet cable in port 4 as well. Once you've done that you'll receive your full speeds.&nbsp;

Go to the Device Manager and change to the table view. What are the link speeds for the WAN/Internet and LAN ports? If you disable QoS fully in the Anti-Bufferbloat 3 line option menu and redo the test does it increase?

I'm not sure what you want me to do. I don't see a speed showing for WAN/LAN. But I posted a screen shot of the table view in QOS. Link attached.&nbsp;
