I have just firmware updated my Deco x20. They have worked with no problem before. The main Deco act as router. My internet modem is in bridge mode. VLAN tagging required by the internet provider.
Via the app I updated to: Deco X20(EU)_V4_1.1.0 Build 20230517
After reboot they were not getting back on the internet? VLAN tagging still active.
I tried reboot of both modem and the deco´s still no internet?
Then to test if there was internet from the modem, I tried the original router supplied by the internet company. No problem wifi and ethernet.
Then I put back the decos and after more time without internet but contact via wifi and the app the decos got back on the internet?
I then put the decos to automatically reboot during the night. This morning no internet? Restarting both modem and decos still no internet?
Then back on the original router again internet. Then back on decos and after some time (more time than usual after reboot) they get internet?
I suspect some error in the new firmware? A lot of changes? But why is the original router needed to sort of prime the way to get internet? Has the decos lost some negotiation ability?
From time to time a reboot is needed but it is troublesome that I have to plug back the original router and then back after every reboot?

My fiber modem is:
ICOTERA I6851
It is in bridge mode and is working with no problem with the router delivered from the internet provider.
As stated it is only on restart (modem and/or deco) the internet fails. When first plugging in the original modem, obtaining internet. Then switching to deco the deco re-obtains internet connection.
As mentioned I have set up cloned MAC address (no luck). My internet provider uses VLAN tagging (this have been setup and working al the time).
The problem is when either the power is down or a simple restart is needed one has to plug in plug out the original router to obtain internet acces? That is a bit trouble some.
The only thing that was changed was the recent firmware update. Unfortunately I am not sure what version I was using before? So going back could also hold a risk that it was an earlier update which introduced the problem? And then a lot of downgrading is needed?
It seems like the deco is unable to obtain the correct addresses on its own? But if the original modem does it first it is working?
Any other suggestions?
