Troubleshooting

n Important – disabling default dialup connections

If you have previously been using a dialup (analogue or ISDN) connection to the Internet, you are likely to

have configured Windows to use this as your default Internet connection. You may also have configured your

web browser or email client (or both) to “always dial my default connection” for convenience.

Unless you tell them otherwise, these programs may keep trying to dial up to the Internet (or at least may

open a dialup networking window) when you start to use them – ignoring your new broadband connection!

This is easily fixed by reconfiguring the program(s) in question. Typically, the most important program to

change is Internet Explorer as many other programs will automatically use the same Internet settings it does.

To prevent unwanted attempts to establish a dialup connection, you should do the following:

• In Internet Explorer you should go to Tools / Internet Options / Connection and change from

“Always Dial my default connection” (if this is selected) to either “Never Dial a connection” or

“Dial when a network connection is not present”. This will cause your browser to try to connect

to the Internet using your LAN connection (via your P623 router) instead of using a dialup

connection. You should also click on “LAN Settings” and make sure all 3 tick boxes are unticked.

• Outlook (Express) can be configured to use a specific dialup connection for each email account. If

these are currently configured to use dialup connections, you will need to change them to use your

LAN connection. (Look in the “Connections” tab under the “More Settings” dialog for the email

account(s) you want to change in Outlook.)

If you get browser errors asking if you want to “Retry” or “Work Offline”, this may indicate that your browser is

trying to access a dialup connection that is not available. In this instance, choose “Work Offline” to clear the

error message, then follow the instructions above to disable dialups.

TIP: Regardless of whether your computer uses Ethernet or USB to connect to

your Prestige 623, Windows considers it as network / “LAN” connection because the

ZyXEL Prestige 623 USB Driver software is viewed as a type of network card.

n Checking/updating your computer’s IP address

1. On your computer, click Start, (All) Programs, Accessories and then Command Prompt.

2. In the Command Prompt window, type "ipconfig" (or “winipcfg” on older versions of Windows) and

then press ENTER to verify that your computer’s IP address is in the correct subnet (in the range

between 192.168.1.2 and 192.168.1.254 if using the default Prestige LAN IP address). Alternatively,

to have the Prestige assign your computer a new IP address (if your computer is configured to accept

a dynamic address), make sure your Prestige is turned on, type "ipconfig /renew" and press ENTER.
