CAX80 Stuck at 100mbps when using Multigig Port for Ethernet
Just started yesterday, my CAX80 multigig port no longer works beyond 100mbps. Tried with 2 different NIC on my motherboard, both produce same result. Also switched my ethernet cable and same results. Did a few reboots, driver installs, and nothing seems to be working. I also did a factory reset on the modem/router twice and same results. I also tried to manually edit the speed in the device properties and that also did not work, and would either not recognize the internet connection or would still revert to 100mbps. Tested my phones and laptops all work great over WiFi with correct speeds.
Then I tried my LAN1 port and discovered it works but maxes at 1000mbps which is what it's rated for. Using the Multigig port I was getting between 1100-1300mbps down on my Xfinity connection. Does this sound like a dead port or a damaged port? Is there anything else I can try to restore my multigig port to full working status?

What is the mfr and model# of these NIC adapters your using?
Something i have seen with mine though I have a Orbi RBR850 connected to mine making a 2.4Gb connection.
Network Card: Aquantia AQtion AQC107 10Gbit Network Adapter
Network Card: Intel I225-V Ethernet Controller
Both exhibit exactly the same issue of max 100mbps connections and both were working 100% until just a few days ago. It started out of nowhere, no Windows or drivers updates were applied or changed. I verified the driver version and even tried to clean reinstall the driver. Tried different cables, and issue persists.
Both network adapters work 100% at 1000mbps link when switching to the LAN1 port. However that isn't a "fix" as the Multi-gig port should work as intended like it did before.
Does it sound like I need to start an RMA with Netgear?
I would yes. Keep us posted on how it goes.
