Thought this might interest those that may still have doubts regarding NV2.
I started using 10Mhz channel widths a while back in combination with 2.4ghz Gmode only.
see attached, the customer has been connected for 111 days without single interruption to signal.
The rest of the clients disconnects are influenced by interruptions in the mains electrical supplies, but even if there is a dropout, it usually reconnects within the same second!
Anyone else had NV2 clients running for more than 111 days.
In RouterOS v5.22 we have optimized the Nv2 protocol stability. Now it should work even better and you should see even less disconnections. You need to upgrade the AP and also the Clients to v5.22 in order to get better Nv2 stability.
