Network Adapter Cards

Expand the network connectivity on your server, desktop, or laptop with our network adapter cards.

We offer a variety of products to enable or upgrade a wired Ethernet connection to the network for improved speed and reliability:

  • PCI Express (PCIe) add-on cards to upgrade desktop or server networking, up to 10 Gbps
  • Multi-port PCIe network adapters, including 2 and 4-port cards
  • Power over Ethernet (PoE) solutions to supply power and network connectivity over the same cable
  • ExpressCard network adapters you can use as a workaround in place of a damaged RJ45 port on your legacy laptop
