The invention discloses a method for intelligently selecting and automatically dialing a
wireless wideband access network, which comprises the following steps that: a user starts a C+W
client,
software detects whether devices of a computer are available, and if the devices are not available, the
software prompts the user directly and quits; if the devices are available, the
client searches the network to find whether a
wireless network exists; if an network
signal is good and available, the
client reads the previously-stored
authentication information automatically and starts to connect and authenticate; and when the client logs on successfully,
network connection modes, the online time length, the network flow and the like are displayed to the user. The method achieves '
intelligent network selection and automatic dialing', can access to the network without clicking 'connection' manually by the user, can access quickly, can prompt the user when the network is disconnected, and can reconnect again after the disconnection.
