Cannot connect to the network

If your Broadcom BCM9430

wireless device appears to be functioning properly but you cannot connect to the network, the problem

may be that there is a mismatch between the

Network name (SSID)

and

Wireless network key (WEP)

settings in your Wireless

Network Properties and the name and WEP key of the network you are trying to connect to. As explained in

Completing the setup

, the

network name and WEP key are case sensitive. Verify that the spelling and case of these parameters are correct and that the settings

are exactly the same on all computers on the network.

If you have verified that the spelling and case of these parameters are correct and that the settings are exactly the same on all

computers on the network and you are still unable to connect to the network, see

Performance and connectivity problems
