iMesh bonding not working with 388.3 (AC86U)

[MarkusI]

Hey,

I yesterday tried to add a new iMesh node (AC68U) to an iMesh managed by an AC86U (Merlin 386.11).
I tried this with the AC68U on 386.11 and 3.0.0.4_386_43129 with no success (it always stopped after a few seconds).

I remembered that I had a similar issue when adding another AC86U to the same network 1 1/2 years ago and what worked was to downgrade the managing node's firmware for the bonding and the upgrade it again.

That's what I did: I downgraded the central AC86U to 386.1_2 and adding the new node worked like a charm.
After that, I upgraded back to 386.11.

Is this a known issue?

Thanks
Markus
