Hi.

I try to update my USG 20 (non wireless) fomr V3.30 to the newst one. Unfortunately the earliest firmware I able to download is 4.16. But I need the versions between as the updgare not working strait to 4.16.

Can I find all the needed files up to V5 ?

Usg 20, are you serious in 2024? It's high time to get rid of this outdated and slow equipment.

so if i got it free i should not start to learn about fw?.. nice

I saw newer firmwares on the support site. Is that not possible to install only if I would do it earlier?

Kind regards
