Slow Wan speed < 200mbps hardware issue?

I've had a Precision t3600 as our firewall for sometime. Xeon E5, 32GB ram. We have the Jeirdus with Intel Chipset 82546 Dual Port Gigabit 8492MT PCI Server Network Card 1000M RJ45 NIC Ethernet Desktop Adapter (
https://www.amazon.com/Jeirdus-Chipset-Gigabit-Network-Ethernet/dp/B07CGZD7YJ/ref=sr_1_2_sspa?crid=37Z85IG2PFYWK&keywords=2.5gb%2Bdual%2Bnic%2Bintel%2Bpcie&qid=1692974865&sprefix=2.5gb%2Bdual%2Bnic%2Bintel%2Bpcie%2Caps%2C95&sr=8-2-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1
).
This card is used for our wan connections, we have two coax and fiber.
one vlan and lan. Other than that i've read through a ton of forum posts and checked to ensure hardware offloading, etc were all disabled. No shaping policies. Wan connections both say: 1000baseT <full-duplex>
We recently went to 300Mbps fiber. Speed tests won't go above 170-190. If plug a laptop directly to the modem, 290Mbps all day long. Its definitely the firewall. The fiber carrier says they can see errors but could be our equipment or theirs... since I can get the proper speed directly connected, i'm betting it's opnsense.
1. Is it this card or the drivers for this card? It's older PCI.
2. Is there a better card that is truly dual nic (dual controllers)?
I tried to go through as many forum posts and reddit threads as I could before making this post. It's possible I missed something. We have updated to 23.7 still nothing changed.

This NIC is a chinese knockoff of a 20 year old Intel 82546 chip. This is the most likely cause of the low throughput.
I couldn't find information if it supports RSS. Just replace it with an Intel I350-AM2 and you should have full throughput.

discovered that... ordered a protectli fw4c. It's what I have at home running opnsense... really don't need a xeon e5, it was just handy at the time.
I'm going to guess the protectli will have no issues with the throughput.
