Question: I am seeing a message in Windows taskbar stating; "GPRS a
Network Cable is Unplugged". What does this mean?
Answer: Typically, this message appears if your VAIO PC is connected to
the Cingular GPRS network and is allowed to go into hibernation. Upon
resuming, Cingular has terminated the connection. However, Windows
information has not yet been updated to recognize this change and is
unaware that your GPRS connection does not require a cable. You may
either re-connect to Cingular, or simply cancel out of the message.
Question: Downloads sometimes appear to be slow when connecting to the
Internet via CCM. What type of download speeds should I expect?
Answer: Since CCM operates over a cellular network and is subject to the
same issues/conditions as cellular connections, bandwidth may vary greatly.
Common download speeds ranging from 18~64Kbps are possible with
30~36Kbps rates as typical. However, these are only estimates and your
actual experience will likely vary depending upon a number of
environmental factors.
Question: What is meant by "RWIN" from the CCM Tools settings
advanced networking section?
Answer: The TCP Receive Window size is the amount of 'receive' data (in
bytes) that can be buffered at one time on a connection. RWIN (TCP Receive
Window) can be changed using the method of setting up the variables to
optimize TCP. We recommend that this setting not be changed unless you are
an expert or you have explicit instructions from your network administrator.
Note: Changing the settings for this value also has an effect when using
WLAN device or any device that depends on TCP connection.
