Windows® XP
To verify that the correct driver is installed:
1. Uninstall the existing driver.
2. Install the Windows XP driver from the Sprint Mobile
Broadband USB modem installation CD.
To uninstall the existing driver:
1. Open the Control Panel by selecting Start > Control Panel.
2. If “Pick a Category” is displayed, select Switch to Classic View.
3. Double-click the System icon.
4. Click the Hardware tab.
5. Click the Device Manager button.
6. Locate the device entries by using the “+” signs to expand
the listings. (For example, to see all the installed modems,
click the “+” sign to the left of Modems.) The device should
have these driver entries listed in Device Manager:
Ⅲ The device driver should appear under Modems as
Novatel Wireless Expedite EV-DO Modem.
Ⅲ The device should appear under Network adapters as
Novatel Wireless Expedite EV-DO Network Adapter (if
Network Adapter (NDIS) is enabled).
Ⅲ The device should appear under Ports (COM & LPT) as
Novatel Wireless Expedite EV-DO Status Port (COM#).
If the listings above do not appear, identify the listing for
your device by unplugging the USB connector. This causes
the driver listing for the device to disappear from the list.
Reinsert the device again to cause the driver listing to
reappear. You can identify the entries for your device by
observing which entries are affected when you remove and
replace the USB connector, or by disabling Network Adapter
(NDIS). (See “Novatel Wireless Network Adapter (NDIS)” on
page 91.)
