When enabling AP Mode on ASUS AC87U, wired speed abysmal. Why?

[Jaseinatl]

I have Comcast service and use their modem/router combo for my network. I have tried a dozen other modems and none of them give me 300mbps other than the Comcast device. It has built-in AC WIFI, but it doesn't reach the back half of my house.

I had the ASUS AC87U as my primary router before this Comcast device. I set it up with a dedicated IP address outside the DHCP assignment range of the Comcast device and connected it via RJ45 Cat 6 Cable from LAN to LAN. I setup the ASUS to be an Access Point and copied the SSID and password for both WIFI bands on the Comcast device. I also made sure not to use conflicting channels.

Everything works, but when I check my speeds from wired connections that use the Access Point LAN ports, I get faster upload speeds (24 mbps) than download (18 mbps). It should read 32 up/300 down.

What am I doing wrong?

Thanks in advance for any help.

First try to disable the wireless in the AP just to be sure it is not something strange in the software causing this.

The lan ports are a switch. In many routers it is a actual separate chip so the traffic never even goes to the CPU chip in the router. These tend to be asic based devices that do not delay the traffic. I would be suspect of a bad cable.

At first I thought this was a joke. I mean the main reason I use the WIFI AP is for WIFI access for half of my house. However, I tried disabling both WIFI channels and the speeds increased to 295/30.

The strange thing is that re-enabling both WIFI channels left the speeds at 295/30...very odd.

Regardless, problem solved. Thanks for the advice.
