Just got this router and already having issues as I have seen doing some reading on speed. Updated to the newest firmware also. So, I have cable internet 500mbps and 20mbps upload. When I plug straight into the modem I am getting about 530mbps (PC to Modem). When I plug into the AX11000 I am getting a steady 90mbps and 20 upload. Same for Ethernet and WiFi. Some have said go into the HomeCare-QoS and select Manual. I did that and did 25mbps on the Upload and 600mbps on the Download. I rebooted the router and it is the same. What is going on here? Ideas to try?
