WEP encryption process by automatically generating the WEP encryption keys for Linksys products Dual Band Wireless A G PCI Adapter PCI Peripheral Component Interconnect A peripheral bus commonly used in PCs Macintoshes and workstations It was designed primarily by Intel and first appeared on PCs in late 1993 PCI provides a high speed data path between the CPU and peripheral devices video disk network etc There are typically three or four PCI slots on the motherboard In a Pentium PC there is generally a mix of PCI and ISA slots or PCI and EISA slots Early on the PCI bus was known as a local bus PCI provides plug and play capability automatically configuring the PCI cards at startup When PCI is used with the ISA bus the only thing that is gen erally required is to indicate in the CMOS memory which IRQs are already in use by ISA cards PCI takes care of the rest PCI allows IRQs to be shared which helps to solve the problem of limited IRQs available on a PC For example if there were only one IRQ left over after ISA devices were given their required IRQs all PCI devices could share it In a PCI only machine there cannot be insufficient IRQs as all can be shared Plug and Play The ability of a computer system to configure expansion boards and other devices automatically without requiring the user to turn off the system during installation Roaming In an infrastructure mode wireless network this refe
