Only Getting 1/3 of the Advertised Speed When Using My ASUS Router

I switched from Comcast Fiber Gig Internet to AT&T Fiber 300 recently,  unfortunately I'm only able to get approximately 100 mbps when using my own router.  With the Comcast Fiber, I directly connect the ASUS router to the DOCSIS 3.1 modem and was able to get consistent 800mbps+ speed, whereas when I connect the same router to the AT&T issued Arris BGW210-700 gateway, I'm getting only approximately 100mbps.  I have tested that if I connect the computer directly into the Arris gateway, I can get 300mbps.

 

In addition, I have configured the Arris gateway in passthrough mode to my ASUS router already, so in theory, the gateway should behaves just like a modem.  Anyone else here experiences the same problem? If so, can you please let me know how I can address this issue?

What kind of router?  Does it have 100 Mb/s Ethernet ports?

It's an ASUS AC1900.  The ports are gig E.

Did the port(s) negotiate to 1G?  What does the "LAN Ethernet Statistics" show for each of the ports on the gateway's "Home Network" tab?

Yes, it's negotiated at 1G.  The LAN Ethernet Statistics shows transmit speed of 1000000000.

If QOS is turned on. Turn it off. You may also try factory resetting both devices and start over. How are you setting up ip passthrough?

The ASUS router's QOS is off.  I'm not aware if there's QOS settings in the Arris BGW210-700 gateway (I look through the menu and did not find any QOS settings).  The IP pass through is via DHCP fixed MAC address just like the article you quoted.  I had also reset the devices since there are not any special configuration that I need to retain.  The router works fine with the Comcast cable modem.

Hi, @TGSLIT, I would love to help with you with your router speed.

We recommend a factory reset on your gateway, be aware this will delete your custom settings, such as static IP addresses, and Wi-Fi network names (SSID), so make sure to write these down prior to the reset.

Following this, you should configure IP passthrough, this will help in optimizing your connection with your third party device.

We also suggest running through our basic troubleshooting steps for your gateway, to ensure your gateway / connection is properly functioning.

Please let us know if these steps help, if not, we may need to Direct Message you, and run diagnostics on your line to look further in to this for you.

I will give this a try. I'm crossing my fingers, but have seen these steps done with other people with no avail.
