We had three customers with the issue in the last month - two of them could only resolve the issue by rebuilding the GW from scratch. Steps that minimize downtime:
- get a same model SMB unit
- open WebGUI for both units at once and configure the other unit with identical settings
- make a backup from the other unit with identical settings
---> downtime begins
- restore this backup to the unit with the issue
---> End
- re-activate the license
