Hi, Fabrice My situation is like that:
Node 2 ---> Node 1 (portal) ---> PC Node 3 ---> When I bring down Node 2, it will become Node 3 ---> Node 2 ---> Node 1 (portal) ---> PC It will restore probably when you bring down Node 1 Node 2 ---> Node 1 (portal) ---> PC Node 3 ---> I think that similar to what Fabrice faced. Perhaps, we should set mesh_hwmp_rootmode to 1 or mesh_gate_announcements to 1. Javier and Thomas perhaps can comment on this.
