  @ElSrJuez Hi, welcome to the community.

As far as I know, the latest firmware 1.2.1 of Deco X3600 hasn't made any changes to Access Point mode.

Could you please provide more details about what issues you have suffered on AP mode after updating to 1.2.1?

 

And When I checked your TP-link ID, I see one of the Deco X3600 is 1.1.3, and the other is 1.2.1. If possible, would the same issue continue if we let the Deco X3600 with 1.1.3 as the main Deco and remove(or unplug) the one with 1.2.1 from the Mesh network?

Thank you David-TP, 

To answer your question, again: My Deco network had been working for a long time very well in AP mode until I accepted the suggestion to upgrade the firmware to v.1.2.1, the upgrade installed succesfully, the Deco's rebooted but when coming back, they would not connect to the Internet. I made no other changes at the time other than the the firmware update.

Since nothing was working, I factory-reset my main Deco, I recreated a network, it went into Router mode by default and it works. But since then, as soon as I switch again to AP mode, I can still connect to the Deco wifi but I dont get an IP address from the router via Ethernet, internet doesnt work.

I have tried many times since then with each deco individually, i reverted the firmware in two of them (thats why now you see them different versions). but none of that has made any difference, they only work in Router mode.

Which sucks big time : (
