thank you very much s_vald,
I'm also using mesh with 2 nodes. The Backhaul Connection is wireless and with the latest updates it was very unstable, the second node was non stop blue led blinking and in the syslog were many messages :
- BHC: WiFi connection status change
- BHC: Disconnected from CAP
- MISC: wifi upstream is connected, and disconnected from CAP.
I've tried everything, even liming the the bandwidth of 5Ghz-2 to 20Mhz and probing every channel from 100 to 140, but with no luck.
So after i've read your post i've did the same:
- kept main node at 3.0.0.4.388_22068
- downgraded second node to 3.0.0.4.388_21099
I didn't reset anything and I've set BHC back to optimal - the bandwidth of 5Ghz-2 is 160Mhz with auto channel.
Now the BHC is stable and there are no more strange massages in the syslog.
