I have rachio gen1 and was not able to connect to orbi mesh network that give both 2.4 and 5 ghz. For hours and hours I tried the following methods with no help:
- disable the 5ghz
- adjust the orbi channels
- Disable internet security
- use AP Mode in orbi
- get help from rachio support
- get help from orbi team.
Both teams insisted to use my old Netgear router. But it finally gave up and died.
Finally I tried to reset the orbi to factory settings and connect rachio as soon it is done. Finally was successful.
