To verify that the correct driver is installed:
• Locate the existing driver
• Replace the driver with the Windows Me driver from the
AirCard installation CD.
Locating the Existing Driver
1. Open the Control Panel by selecting Start > Settings >
Control Panel
.
2. If the System icon is not in the window, view all Control
Panel options
.
3. Double click the System icon.
4. Click the Device Manager tab.
5. Locate the AirCard entries by using the “+” signs to
expand the listings. (I.e. to see all the installed modems,
click the “+” sign to the left of
Modems.) The AirCard
should have 3 entries:
1 The AirCard should display under Multifunction adapters
as
Sierra Wireless AirCard 555 PC Card Parent.
2 The AirCard should display under
Modems as Sierra
Wireless AirCard 555 Modem
.
3 The AirCard should display under
Network adapters as
Sierra Wireless AirCard 555 Adapter.
If the listings above do not appear, identify the listing for
the AirCard by ejecting the AirCard. This causes the driver
listing for the AirCard to disappear from the list. Reinsert
the AirCard again to cause the driver listing to reappear.
You can identify the entries for the AirCard by observing
which entries are affected when you eject and reinsert the
AirCard.
