New Orbi firmware 2.1.2.18 update issues?

Hi,

I wanted to wait a couple of weeks before posting about my upgrade to 2.1.18.

I have a Linksys WRT1200AC running OpenWRT as the router (wifi disabled) and the Orbit and 2x Satellites as AP.  

• Daisy Chain Enabled
• Beamforming, MU-MIMO & Fast Roaming Disabled

As I mentioned in a prior post I have a raspberrypi (stationary, not roaming across the system) monitoring that the three Orbi devices are up and running. Monitoring among other things is pinging the 3 Orbis, checking that the 6 SSIDs are broadcasting (3x 2.4 Ghz + 3x 5Ghz), that different stationary wireless and wired devices on my LAN respond to ping, that DNS is working and that pinging 3 different internet hosts is successful.

 I have had no issues for 2 weeks in a row, no reboots, no SSIDs drops, or lack of connectivity to my LAN or the Internet. WiFi speed and coverage are outstanding.

I briefly tried to enable fast roaming and the reboots and disconnection started happening again, so in order to keep peace at my home, I have not touched the configuration anymore.

Roaming does not work well, when moving around the house I find myself turning off/on my cellphone wifi so it picks the closest Orbi.

Though the Orbi system can be considered by many a configure-and-forget device, not being able to enable key features due to its instability¸ which I expected and paid to work, like fast roaming or beamforming it is disappointing.
