Section 3: Using the PCS Connection Card
104 3F: Troubleshooting Tips (Notebook PC)
Error: Connection Seems Slow
When you have a both a PCS Connection Card and an
AirCard 300 in your computer, the data connection seems
quite slow.
Error: Connection Gets Dropped (Windows 2000 and XP)
When attempting a data connection with PCS Connection
Manager, the connection gets dropped as soon as it is
established (the status goes from “Authenticating” and
“Authenticated” back to “Ready to Connect”).
Possible Causes Suggestions
Under some operating systems, if both
cards are inserted, then the path that the
Internet Protocol (IP) traffic will take is
not predictable. If the data gets routed
through the AirCard 300, you will
experience slower data transfer rates. Before you use the
PCS Connection Card, eject
the AirCard 300 from your
computer.
Possible Causes Suggestions
The connection
properties are not
optimal.
