I have a question regarding the sync of config settings between a router and mesh nodes.

In the LAN settings of my router (2927ax), airtime fairness was disabled.
During the sync of the mesh nodes (962C), this was passed as follows:

• X_00507F_WirelessLAN_AP.AirtimeFairness.Enable = 0
• X_00507F_WirelessLAN_5G_AP.AirtimeFairness.Enable = 0

When I check the web config of the mesh nodes, airtime fairness is enabled.

I try to understand why these settings were not properly updated; is the sync unreliable?  Should I update settings in the web config of the nodes and overrule sync settings?

As a test I enabled Airtime Fairness on 2.4GHz on my 2927ax (running 4.4.5.5) and that did not sync to the nodes, so perhaps there is a problem with that setting. On the other hand I see that the 962C is not in the "supported" list of mesh nodes (I have 906's) so maybe there's an issue there? Either way, no harm in making the setting on the nodes. I always check if the config has actually synced when making a change.

Thanks for your reply.
You’re right that the 962C is not mentioned in the supported list, but it should be compatible:

I will update the nodes and keep an eye on future firmware updates.
