AC1750 Slow Wired Connection
Hello,
I have an TP-Link AC1750 router. I recently purchased a new modem (Arris SB6183) in order to get the maximum download speeds (200 Mbps) allowed by my plan. The modem and PC are connected to the router. After setting up the new modem and doing several speed tests I found I was getting the same download speed (83 Mbps) I was getting with my old modem. I contacted my service provider (Xfinity) who had me connect my PC directly to the modem. When connected directly to the modem I was able to get the 200+ Mbps download speeds. When connected to the router, I do not.
The 5G WiFi speed on my Amazon Fire HD (2017) tablet is about 66 Mbps.
The 5G WiFi speed on my Google Pixel 2 is about 235 Mbps
The wired speed on my Dell PC (about 2.5 years old) is 83 Mbps
I read another thread that suggested disabling NAT Boost. I did, and my wired speed is still the same.
Another suggestion I read was changing the Duplex setting from Auto Negotiation to 1000 Mbps Full Duplex. I tried that, and while my wired connection speed stayed the same the 5G speed on my Pixel 2 dropped from 200+ Mbps to 90 Mbps. I changed it back to Auto Negotiation.
I am using CAT5e cables.
What other settings can I change on the router that will allow me to get the higher wired download speeds allowed by my plan?
Thank you in advance.
