Those add-on cards may sometimes be called expansion cards as well, but very few new laptops support ExpressCard or PCMCIA cards.Įthernet is the standard that all routers, switches, and hubs use for wired networks. Some laptops may be equipped with ExpressCard™ or PCMCIA™ card slots, which can be used to add wireless networking. However, compatibility is limited to desktops only. The advantage of expansion cards is that they are able to support more antennas, which can result in better signal strength. The two most common standards for expansion cards are Peripheral Component Interconnect (PCI™) and Peripheral Component Interconnect Express (PCIe®), with PCIe being the newer and faster of the two.
Expansion CardsĪ type of wireless adapter that can also be referred to as a wireless network interface card. The advantage of a USB wireless adapter is that it is portable, easy to set up and use, and compatible with a wide variety of computers. USB wireless adapters look similar to USB flash memory drives, though some models may have protruding antennas.

Though external, they’re built in a similar way to the NIC adapter most modern computers come with and can enable both wired and wireless connections.ĭeveloped in 1992, the PCI standard was later replaced with PCI Express (PCIe). These adapters also have an attached antenna designed to receive a wireless internet signal. Similar to USB adapters, a PCI adapter connects to a PC computer or laptop via a PCI card slot. Peripheral Component Interconnect (PCI) Network Adapters Jiggo_Putter Studio/ Wired or wireless, they’re often packaged with home routers to form a home LAN. USB network adapters can also support wired network connections.
NETWORK ADAPTER INSTALL
These adapters are a good option for enabling older computers with a wireless connection because they don’t require physically opening the computer’s case to install an internal network adapter.
