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 Sprint Mobile Broadband USB modem 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 the
Sprint Mobile Broadband USB modem by unplugging the
USB connector. This causes the driver listing for the USB
modem to disappear from the list. Reinsert the USB modem
again to cause the driver listing to reappear. You can identify
the entries for the Sprint Mobile Broadband USB modem 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 53.)
7. Right-click Novatel Wireless Expedite EV-DO Modem.
8. Select Uninstall from the pop-up menu.
9. Click OK to confirm the uninstall.
