My experience two weeks ago, trying to install a more “intelligent” Netgear managed switch in my house has taught me about the reality of many IoT devices and simple consumer networking gear. Most need some form of broadcast to operate efficiently, or even at all in some cases. To make that Netgear switch work with a Netgear ORBI wireless system (wired backhaul), I had to do the following steps to remove any switch functions that might filter out required broadcasts… Sense and Kasa apps also had trouble until I changed these default settings:
STP:
A. Login to the management page of the switch
B. Select Switching > STP > Basic > STP Configuration.
C. Next to Spanning Tree State, Select Disable and click on Apply
IGMP Snooping:
A. Login to the management page of the switch
B. Select Switching > Multicast > IGMP Snooping > IGMP Snooping Configuration.
C. On the IGMP Snooping status, select disable and click Apply
DHCP Snooping:
A. Login to the management page of the switch
B. Select Security > Control > DHCP Snooping Global Configuration.
C. On the DHCP Snooping Global Configuration, select disable and click Apply
