According to techinfodepot.shoutwiki.com it support 100mbps on WAN and LAN ports

Associated Stations show 144mbps/144mbps

  • Is flow offloading enabled?
  • Is this thru a Wireguard tunnel?

Try disabling and test - since it's set above the 100 Mbps anyway.

As you found connecting to the ISP gateway (ONT) wifi directly, about 45 Mb true throughput is the limit of 2.4. Also of course you can't get more than 94 Mb on a Fast Ethernet port, accounting for packet overhead.

Setting the QoS slightly lower than your worst bottleneck will improve bufferbloat, but of course the speed can't be increased. With this router you can't use the ISP speed that you're paying for.

...enable it. :person_shrugging:
