2.2.7 Internet connection with GPRS
The configuration of the connection is exactly the same as UMTS (see 2.2.6 Internet connection with UMTS).
However, internet providers use different inistrings for GPRS configuration. The mobile phone provider, who
has equipped you with the SIM card, provides you with the required GPRS settings.
2.2.8 Connection Test
After the internet connection gets defined, the possibility exists to immediately test the configured internet
connection if a successful connection to the internet can be established.
Therefore press the „Connection test“ button.
Press the „connect“ button to test the configured internet connection (depending on the quality of the con-
12
nection, it can take up to one minute). The actual status of the existing internet connection is displayed in
the field „Connection status“:
•
not connected - No connection to the internet established
•
connecting - Trying to establish a connection to the internet
•
connected - Sucessfully connected to the internet
If a successful connection to the internet is established, it is possible to start the PING-test to test the
connection. The PING-test sends data packets to a certain IP address and receives packets again from
this selected IP address. Consequently you can notice if data packets can get send and received from the
internet.
