Works perfectly with OPNsense
Upgraded my Internet Service Plan to 2 Gbps and this little gem fit the bill for my OPNsense firewall upgrade. Worked out of the box no problem. Note, however. If you encounter issues, OPNsense has a Realtek plugin with drivers you can install from the GUI

Works in OpenWRT, need separate driver though.
I bought this to use it in an x86 OpenWRT router. While it does work, I had to do a tiny bit of research to get it to be recognized. I also bought it used (amazon resale / warehouse), and it didn't come with the low-profile bracket that's in the pictures, So I took off a star for that.

Not compatible with Truenas/Debian linux
I don't write reviews but I want people to know before they waste whole day of troubleshooting like I did that this card is not compatible with Truenas Scale / Debian. It says it is linux compatible but even after installing drivers it is not.
