Hello,

I added USB Network card, but it gave me only 100Mb/Full Duplex. After that, I realized that card was 10/100, so I decided to buy a new one.

I purchased new USB Network card with speed 10/100/1000. When I connected it, the speed is still 100Mb/Full Duplex. It is connected to the 1Gb NIC on my server and I know that it should give me 1Gb/Full Duplex.

Any ideas how to improve the speed?

Look at my post, I have tested following adapters:

The Belking adapter works as gigabit. But even with that i get 300 Mbit/s max (seems USB speed limit, same in Windows).

So I would recommend using PCI or PCI Express network adapters for gigabit speeds.

Thank you for your reply.

Device that I use has two NICs and multiple USB slots. It does not have PCI or PCI Express slots. I need the third NIC, so the only option for me is USB NIC and I cannot make it work as 1Gb card.
