Could Omada switches work without Omada software?  i ask this because in the past i had the opposite,  i had a TPlink 1600 switch and it dit always block the network because the router dit block his own ip adres to 192.168.0.1   and the router must always be on 0.1 (as otherwise you miss some devices)

I have a 605 (2) router  and a AP653 on the same network. 

For this moment i have a SG2428P  But it makes to much noice (as i sleep about 1,5 meter from the switch).  So i am planned to buy a Switch without Poe (so no noisy fans)
