Slow Speed on Default Config

[vikest]

Hi Guys, my setup is a not ideal. I have 2 Sabrent 2.5Gb Ethernet USB Adapters, trying to get the most out of my 1.2Gbps speed, which I actually get 1.4Gbps when the computer is connected directly to the modem.

But when the FW is connected, I only get 85Mbps. Any ideas?

When configuring the interfaces on the computer itself (not Web UI), it did detect the adapters as being 2.5, after the configuration, they show up as just "USB Ethernet". Is there a way to check the actual link speeds before moving on to other troubleshooting?

The hardware is an Intel i5 1035G1 desktop

Thanks!
