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!
 
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
