I bought a 2.5Gbe PCIe adapter on amazon.com last month. It cost me $19.98 plus tax. But now it is $25.89.

It is a small box with the brand name on the front, ubit. I have no idea what kind of brand it is.

Ubit 2.5Gbe adapter Very simple packaging. I like it.

I opened the box. You can see the all stuff inside.

  • one PCIe adapter
  • a user manual
  • a screwdriver
  • a pack of screws

Look the card closer.

I checked the Ubit official website, the model is LE8105. Chipset is Realtek 8125BG.

This PCIe 2.5Gbe adapter is installed in my Proxmox Ve system. I make an iperf3 test on it.  My desktop is running with a 10Gbe card. I run iperf3 as a server on the Proxmox Ve. The result is shown below.

iperf Done.

I am happy with the result. I can get 2.36Gbits/sec on a 2.5Gbe network card.
