Hello,
I tried OPNsense on a mini computer and plugged a 2.5gbps USB adapter on a USB 3 port. OPNsense recognized the adapter as being cdc, adapter shows it is connected at 2.5gbps, my isp supports up to 1.5gbps which for now tops at 1.2, tested with a laptop running Ubuntu with the same USB adapter.
OPNsense gets 100mbps up and down, nothing more! Is there a way to make it run full speed?

Thanks.

With real network interfaces, yes. With USB, most probably no.

Why with USB no?
I tried running OPNsense virtually on the laptop wiht Ubuntu, connected the USB adapter to the virtual OPNsense with virtIO type and the performance were what I was expecting them to be...

Seems like a driver difference given the different scenarios. Likely the natively built driver is not optimal for the device.

Have you tried installing the realtek driver available in the packages repo?
