Hi,

I bought this unit so I could do a failover setup once my fiber gets installed (with starlink as the backup). For now I use starlink as the main WAN. It all worked but I try to upgrade the firmware and get an error. 

Unit came with 2.2.5 Build 20240522 Rel.75860 and I try to install ER605(UN)_V2.20_2.3.3 Build 20251029. But every time I try I get: "Upgrade Failed. Please check the upgrade file and try again". I checked the file it seems fine. Any suggestions? 

On a side note any known issues to use this unit with starlink and then my deco as an Access Point?
