Setting WiFi Security on your CradlePoint Router

Your USB Modem or Phone Does Not Work With the Router
1) If your USB data modem or phone is not working with the router, check the list of supported
devices to ensure you are using a supported device and carrier. The device you’re using
must be supported on the carrier network providing your cellular service or it’s considered
an unsupported device, even if it is supported on another carrier’s network.
CradlePoint’s supported device list changes regularly. We update our supported device list
after a device is certified and approved. If the device you have is NOT on the list, that means
we do not support it at this time.
6) Configure security by selecting either ENABLE ADVANCED SECURITY CONFIGURATION
7) When you select ENABLE ADVANCED SECURITY CONFIGURATION, you can rename
your wireless network and select your security mode: GOOD for WEP, BETTER for WPA
and BEST or WPA2. (Make sure your PC or other devices support the mode you choose.)
Enter a personalized SECURITY PASSWORD.
8) Only select REQUIRE USER LOG-IN if you wish to force every user of the router to log-in
using the User Login Password (Set in a separate location in the User Interface), click NEXT.
9) Record the setup information shown on the final summary page, then click CONNECT.
This will save your new settings and reboot your router to operate based on your new
security information.
You’ve now secured your CradlePoint router from unintended WiFi access.
