@Clive_A As we wrote here I have a question to the ER7412-M2 about the firmware updates.. just don't wanna full fill now the other ones inbox..

Do you know when the ER7412-M2 will get a new firmware/ new pre-releases or betas?

Because currently I'm missing functions most models of the Omada series got already.. like SD-WAN or FQDN for Wirequard and Virtual WAN

But don't get me wrong I don't wanna know a date more if it can be expected soon like in a month or if there is nothing planed/ the devs did not announce something..

The reason why I'm asking because there are quite a few issues like with detecting if devices are online or the one in that linked post with the fixed DHCP addresses..

Like since as you said the version is already pretty old (think something like 10 months ago the pre-release/ beta of that version started) and these issues were fixed.

It is also I need a new router with 2 (or more) 2.5gigabit (or more of course) LAN/ WAN ports that is why I'm asking.. and since I need some of these functions for that use case definetly I'm thinking of buying the bigger ER8411 for that case now, even if I wouldn't need so much performance there..
