An icon similar to the __close-network__ instead with a check inside. Can be used to signify a state of node on the network, or an action like check node state.
Thanks.
Some old discussion over here: https://github.com/Templarian/MaterialDesign/issues/369#issuecomment-141575044
Instead of an off variant, how about something like this?

We already have a server-network-off so I feel that it is consistent.
Slight update to @MrGrigri's to make these consistent with each other and others already in the library:


network-off.zip
And the outline variant of check:

check-network-outline.zip
All 4 are added. 馃槂

I believe both of these would be useful.
check-network.zip
network-off.zip
