Regarding to this case,
I tested the wifi with firmware v4.33 without any issue.


 Since you updated the firmware 4.20->4.33, it is a 4 major versions jump, in this case we will suggest users to upgrade from 4.20-> 4.25->4.30->4.31->4.33 or it may have some unexpected result.

OK, so can you give me a link to download old firmwares, my zyxel allow me to download 4.31,3.32 or 4.33 only. Thank you

Hallo,
i am not sure if every "administrator" of a USG is aware that 4.25 and 4.30 are "major versions".

Maybe it should be indicated more clearly in the Release notes or the Firmware upgrade page what are major version upgrades and how to do it correctly.
Thx

Steve84, If the config is not too complex I would probably document and then hit the reset button with 4.33 installed and then reprogram. Charlie what do you think?

Normally we will suggest users to upgrade their firmware version by version to avoid any unexpected result. However, we can also put the upgrading version suggestion in our formal release note in the future release.

@iSpeed
I agree with you and actually this is what we just suggested Steve84.
