NOTE: There is a bit of geek-speak ahead here. If you are reading this and none of it makes any sense, it's very likely that it doesn't apply to your home Wi-Fi. These configurations are not common for typical home Wi-Fi networks. If an IT professional helped setup your network, please consult with them if you have any concerns related to your setup.
How many networks can the Circle device manage at a time?
The Circle device only manages one network segment at a time, so for folks whose networks involve a less-common configuration, this is an important detail to keep in mind. If your network has multiple segments, including guest networks, your Circle device will only be able to manage one of them. We suggest password protecting your various network segments, and making sure that your family member's devices only have access to the segment your Circle device is paired with.
How many subnets or VLANs can your Circle device manage at a time?
If you have configured your home Internet to have multiple subnets or VLANs, your Circle device will only be able to manage one subnet or one VLAN at a time. These are treated as distinct network segments by the Circle device, and traffic that flows through the other subnets or VLANs will not be seen by the Circle device. To manage any of the others, you will need an additional Circle device to handle that network traffic.
