@Kevin_ZI I have Archer BE550 v1.0 firm 1.2.1 Build 20250813 rel.27119(4555) as router, and Archer AX10 firmware 1.3.12 Build 20250828 Rel. 26873 as Satellite. It will be possible to have IoT...

If it's not technically possible, at least say so now, openly and frankly.

We need Guest and IoT Networks Mesh-able and extendable

Apparently it's possible. We are still waiting for this very important feature.
