Omen Max 16 2025 with Realtek 2.5gbps NIC capped at 200Mbps - Hardware issue?

My HP Omen 16 internal Realtek 2.5GbE card is stuck at ~200 Mbps on my 500/500 connection. I suspect the card is defective and wanted to see if others have this issue.

Here’s the rundown:

• The speed cap happens on both Windows 11 and Ubuntu with the latest drivers and BIOS.
• An external USB-C to Ethernet adapter gets the full 500/500 speed using the same cable and switch port.
• The internal card correctly reports a 2.5Gbps link speed, but the actual throughput is throttled.

Since the external adapter works perfectly, all signs point to a hardware fault with the onboard NIC.

Has anyone else with an Omen had this specific issue and ended up needing a warranty repair?

Thanks!
