I’ve a long history of complaints and mounting frustrations from my 3x Neeo’s, rarely used them because of these issues, decided to take another step towards fixing things, reading and spending time on UniFi forums, I toke one of their Early access Firmware releases 6.5.33 -> 6.5.37, zero tweaks, Neeo’s are connected and remain connected for 2-3 weeks now! Never happened before!
Conclusions, you need a networking and RF PhD to have Neeo’s work, but when they do it’s a bless!
