TitleHow to achieve the quickest failover time for a primary wan connection
It is possible to reduce the failover time of the primary WAN connection to a much lower time since the release of 6.5.0. Failover can be reduced to ~4 seconds after configuration.
1. Cradlepoint router
2. Multiple WAN connections
1. Upgrade your NCOS to 6.5.0 or later. This process can be found here (NCOS: How to update the NCOS of a Cradlepoint router).
2. Log into your Cradlepoint administration web page or access the device from NetCloud Manager.
3. Go to Connection Manager.
4. Locate your primary WAN connection. This is usually the ethernet WAN profile.
5. Set the WAN verify setting to active ping. Google's DNS server is often used as the target IP (
6. Reduce the retry interval to 1 second and the retry count to 1 second.
7. Reduce the idle check interval to 2 seconds.
8. Set the secondary connection (usually an LTE modem) profile from on-demand to Standby.

These settings will make the Cradlepoint check for an active connection every 2 seconds and spend 1 second trying a second time. After that, failover will occur to the secondary connection.
Additional Information
Performing these steps increases the chances of failing over for a false positive state of the WAN being down. If your connection is experiencing brief loss or intermittent connectivity, your Cradlepoint will failover and it will then fail back to the primary connection based on your failback rules of the secondary WAN (this is usually an LTE modem).
