Problems with deco m9 plus v1 and v2
We're having serious issues with our deco m9 plus mesh. We've been running a three units m9 v1 + one m5 mesh for a couple of years without problems. We recently decided to expand our network with 3 additional m9s as we had a few slow spots and also wanted to replace the m5.
The new units are v2.
The problems started after a couple of weeks with units dropping out of the network, sometimes just a few, sometimes all of them. We've tried updating, reconfiguring the whole network, connecting some of the nodes through ethernet. Nothing helps. The network is extremely unstable.
The last thing we've tried is to run only the v2 units and voila, the network's been stable for several days. But as soon as we tried connecting one of the v1 units to the mesh the network started crashing again.
So there seems to be some sort of compatibility issue.
Any ideas on how to fix this?
