I want to upgrade the firmware on my USG40 from 4.20 to latest. I've registered an account and added my device. However I can't download latest firmware, nothing happens when I select the latest firmware marked green and click download. That got me thinking, do I need to first upgrade to 4.25 and so on, and work my way up to the latest 4.33 or can I update from 4.20 to 4.33 right away? I can't even find the version 4.25 to download.
Any help appreciated!

    If I need to update to 4.25 first, then it is not here: ftp://ftp.zyxel.com/USG110/firmware

    You need to use another browser then IE or firefox due to the download button not working or click firmware download and find your update like that.

    Ok, so I guess Chrome could work? And I still want to know if I need to upgrade in stages, version after version och jump straight to the latest version?

    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.
    Here is firmware link of USG40

    Or you can go from 4.20->4.33 and do a reset

    Will Zyxel put up all models of old firmware in myZyxel firmware download?

    I would disagree... I've been using ZyXEL devices for the last 10 years, and for the last couple of years firmware releases had introduced new bugs (password lockout, NAT 80/443 port problems, WiFi dropping just to name a few), so I always wait a couple of months after a FW is released before using it in production environments.

    I strongly appell on ZyXEL to put more focus on testing new firmware releases rather than introducing new features we don't actually need.
