I recommend you reach out to netgear support and focus on Docsis 3.1/OFDM configurations for not achieving the advertised speed.

I am having the same issue. Xfinity XB7 Gateway in bridge mode connected to RAX45. Paying for 600 Mbps service.

If I run the XB7 in router mode, I am getting 720 Mpbs down. Once I run the Xb7 in bridge mode and connect the RAX45, speed immediately drops to 280 Mpbs.

There is obviously a firmware issue in one of these two devices - I am guessing on the Xfinity Xb7 Gateway side, since it is so new, but I wish they would fix it already. Don't like being stuck between two giant tech corporations whose products aren't playing well together.

Please post about this over in the RAX Forum for your model router:
https://community.netgear.com/t5/Nighthawk-Routers-with-WiFi-6-AX/bd-p/en-home-routers-nighthawk-wifi-ax6

This forum and thread is for the CAX80 which is a gateway modem/router.

Thank you.

Just spent 1.5 hours on the phone with Netgear support tech engineer, had me change wireless channels and do a reset, of course no luck. Claims there is no beta firmware to fix my issue. I'm at wits end with this. No one is willing to help!!
