USB network adapters can be convenient, but USB 1.1 sockets are much slower than 10/
100 Ethernet and slow down any USB-attached network interface. USB 2.0 sockets and
devices are satisfactory for connecting 10/100 Ethernet USB adapters but they are com-
pletely inadequate for Gigabit Ethernet adapters. If you truly want Gigabit Ethernet per-
formance, avoid USB and use a PCI, PCIe, or ExpressCard-based card instead.
On the other hand, when adding wireless networking to desktop systems I recommend

•
Installation
—You don't need to open the system to install a USB device.
•
Portability
—You can easily use the USB device with any other PC.
•
Signal strength
—You can more easily achieve optimal antenna placement with a
USB device, especially when attached to the end of an extension cable.
For the best performance systems should be connected via a Gigabit wired connection,
wireless should only be used if a wired connection isn't possible or cost effective.

Installing the Network Adapter
When installing an internal network card, follow this procedure:
1.
Open the case and locate an open expansion slot that matches the type of NIC you
purchased (preferably PCI or PCI-Express).
2.
Using a screwdriver, remove the screw securing the slot cover at the rear of the case.
3.
Insert the card gently, ensuring that the edge connector is seated solidly in the slot.
