Thanks for the reply. The issue is not even about Mesh roaming, it is about - connecting to the WLAN. I am practically sitting in front of the Deco, not even 5 feet away and I having these connection...

I also have issues with 2.4Ghz Wireless Clients. For unknown reason the clients keep dropping - it appears to be very unstable. When I connect to just 2.4Ghz SSID that I setup for legacy clients....
