I want to connect to multiple Access Points.
You can register up to four Access Point connection settings with the Wireless Palette. This way, you can switch connection
from one PCWA-A100 Wireless LAN Access Point to another without being troubled with reconfiguration each time you change
the destination. However, you cannot connect simultaneously to multiple Access Points.
