Potential Problems & Their Solutions:
There are occasions when the connection doesn't work, in these cases check your firewall software and make sure it allows you to connect to the Wi-Fi network. To check this, disable your firewall software and check the connection again. If you can connect with the firewall program disabled, you will need to change your firewall settings. If your firewall program is not the problem check the SSID and WEP key information that you entered. Both of these are case sensitive. If you had obtained SSID information from the Internet, check with someone in the establishment to see if the SSID has been changed.
