NBG-417N User’s Guide 241 A PPENDIX D Wireless LANs Wireless LAN Topologies This section discuss es ad-hoc and infr astructure wi reless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configurat ion is an in dependent (Ad-hoc) WLAN that connects a set of computers with wireless stations (A , B, C) .
Appendix D Wireless LANs NBG-417N User’s Guide 242 with each other. When Intra-BSS is disabled, wireless stati on A and B can still access the wired network but cannot communicate with eac h other.
Appendix D Wireless LANs NBG-417N User’s Guide 243 An ESSID (ESS IDentification ) uniquely identifies each ESS. All ac cess points and their associated wireless stations within the same ESS must have the same ESSID in order to comm unicate.
