Tap on the OK button.

While automatic connection mode is enabled, the Connect Data button in the main Wireless 
LAN dialog box changes to Disable Auto. 
To close the currently active connection (if any) and disable the automatic connection mode:
•

Tap on Disable Auto.

Use Virtual Serial Port
If Use virtual serial port is enabled, packet data connections are established through the 
virtual serial port of the WWAN driver rather than through the WWAN driver directly. This 
checkbox should only be checked if certain third-party VPN (Virtual Private Network) 
clients are used that do not work correctly otherwise. The default setting is disabled 
(unchecked).

Enable Automatic Configuration
In most cases, the data connection is configured automatically and no user interaction is re-
quired. This is true even if multiple SIM cards from different operators are used with the 
same device. The connection parameters are adjusted automatically when a new SIM card is 
detected (this may require a reset). The connection parameters are retrieved from a database. 
Manual configuration should be necessary only if:
•

One or more parameters in the database are incorrect or a new operator is not yet in the 

database. (The database should be corrected for subsequent software releases.)

•

An operator has assigned individual packet data user names and passwords. 

•

A very large site has their own APN. Such connections always have to be configured 

manually.

•

A customer has subscribed for a static IP address. By definition this must be configured 

manually.
