[GTER] Desconexão em clientes com ubnt

[Nielsen]

Temos clientes com 5.6.5, 6.0 e 6.0.3 e alguns em teste com 6.0.4
Todos clientes que conectam em AP ubnt (rocket m5) desconectam em tempos aleatórios (1h, 2h, 5h, 10h e etc)
Clientes que conectam em torre com mikrotik isso não acontece, uptime do wireless bate com uptime do equipamento.
Desconfio ser algo relacionado ao EAP ou Radius.
Nos clientes que conectam em AP MK não tem EAP só WPA2, já nos nano tem EAP.
Estou atualizando os rockets para 6.0.4 apesar de no changelog não ter nada sobre isso para testar.
Resumo:
AP MK + SXT = OK
AP MK + UBNT = OK
AP UBNT + UBNT = FAIL
