Establishing wireless connections

This section explains how to get a wireless network going. There are several
different basic operating systems:

Ad hoc network

Infrastructure network

Point-to-point network (wireless bridge)

Wireless Internet gateway ISDN

Wireless Internet gateway DSL

The network structures are described in the introduction of this manual. For
