LTE3302 Brindge Mode Disconnections

Paladium

Hi
i have a Unifi Setup with a Cableconnection at WAN1 and for the Backup a LTE3302 with unlimited Data on WAN2.
The setting works fine in Normal Mode.(Not Bridged)
I can disconnect WAN1 and the Unifi Router make a failover to WAN2.
But for Rechable Reason i need to Bridge the LTE3302.
After Bridging the LTE3302 he try to connect and after a second he disconnect and try it again.

What could be wrong?

Thank you for your Help.

Hi Paladium,

Do you mean that after switching to bridge mode on the LTE3302, the LTE3302 tries to connect to the LTE network but never really successfully connects?

Does the “Status” page show a WAN IP address, as the following image shows?

Also, could you please take a screenshot of the LTE Modem Status page (web GUI > Monitor > LTE Modem Status)?

Thank you.
