The snap can be installed from the Ubuntu Store with the following command

 $ snap install wifi-ap

If you’re running at least snapd version 2.17 all plugs of the wifi-ap snap will be automatically connected to the right slot. If you’re running an older snapd version or a locally build snap you need to connect the plugs manually.

You can verify with the following command that the relevant plugs are connected:

$ snap interfaces
Slot                       Plug
:network-bind              wifi-ap
:firewall-control          wifi-ap:firewall-control
:network-control           wifi-ap:network-control
:network-manager           wifi-ap:network-manager

If you also have the network-manager snap installed on the system then you need to connect the network-manager plug of the wifi-ap snap too. If you have the network-manager installed before you install the wifi-ap snap the plug gets automatically connected. Otherwise you have to do that manually:

$ snap connect wifi-ap:network-manager network-manager:service
