Troubleshoot when you are unable to connect or receive an error when trying to connect your Novatel Wireless MiFi 2200 to the Sprint 3G network
Nov 18, 2013
Several conditions may block connection to the Sprint 3G network and can easily be fixed.
Another Network is Active on your computer

disconnecting the LAN Ethernet cable.
Insufficient Signal Strength
Check the signal strength in the MiFi-2200 User Interface. If the
signal is low, move to another location with better coverage. This error
sometimes results in error code 668 (no signal) which can be viewed in
the WWAN > Diagnostics page of the User Interface. Coverage maps are
available at www.sprint.com/coverage.

menu WWAN > Configuration > Activate Device.
Once activated, it will connect automatically if 3G-Auto Connect is enabled. (Advanced
> Advanced Options > 3G Auto Connect [check]). Otherwise push the
connect button on the WWAN > Diagnostics page to connect to the
Sprint 3G network.
