Roaming
Roaming extends the range of a wireless LAN by using several Access points that use the
same SSID and the same radio channel and are linked via Ethernet. The PCs in the net-
work can switch dynamically between several access points without losing the existing
network connection.
Router
A router directs data packets from one local network (LAN) to another via the fastest
route. A router makes it possible to connect networks that have different network tech-
nologies. For example, it can link a local network with Ethernet or WLAN technology to
the Internet.
