    I have an Asus RT-AC88U router with a Netgear CM1150V cable modem.

    The Router is running 384.13 Merlin - I am concerned only with WIRED connections at this time. All devices have their latest OS and Driver updates.

    I am paying for 500+ download with Comcast/xFinity

    When my PC is connected (wired) to the modem speed tests show 500+mb/s download. When the PC is connected to the router's LAN I am getting 300mb/s download.

    All devices, phones, tablets, PCs, wired, wireless, etc...all behave the same way as far as download speed.

    I did some google-ing and found out that the WAN port in the AC88U usually pegs out above 800mb/s.

    Right now I am using cat5e cables for everything.

    I have tried both Asus stock firmware and Merlin's and they both behave exactly the same.

    I have turned off AiProtection, QoS, traffic analyzer, and NAT Acceleration.

    Asus GUI says that the WAN port is connected 1GB and all LAN ports are connected 1GB.

    1. Will a Cat6/7 patch cable improve performance from the WAN port on the router to the Uplink on the Cable Modem?

    2. Is there a limitation in the firmware for the WAN port in the Router?

    3. Am I missing any configs for the Asus Router?


    Any help is appreciated! Thank you!

    NAT Acceleration needs to be active otherwise you will see those speeds.

    I have tried NAT Acceleration both ON and OFF

    This setting has never made a difference in speed....until now!

    Well, sure as there is ice in my freezer I am not getting about 450mb/s down

    Because you had AiProtection, QoS, Traffic Analyzer, etc. ON before. All of them require CPU traffic processing.
