WAN Gigabit not working

[Williwaw]

Hi,

I can't get LAN/WAN speeds above ~100 Mbps.
My WAN connection is 1 Gbps when I connect directly to the ISP modem (testing with Speedtest Ookla). When I connect using a LAN port I get about 100 Mbps (same computer, same cable cat 6, etc)

Do I need to do any configuration in the router?
What should I check to troubleshoot it?

Router: RT-AC68U
Firmware: 384.15 (Signature version: 2.164 Updated : 2020/02/20 04:34)
Modem: brigded

Thanks in advance,

Williwaw

Go to Tools > System Information > Network and look at

Ethernet Ports > WAN > Link State

and

HW acceleration

Thanks!

The HW acceleration was disabled (incompatibility with IPTraffic); once IPTraffic was disabled, and the router rebooted ... voilá!

Solved.

Thanks again for your prompt response.
