Okay, to my mind that brings us back to "need option to specify wifi regulatory domain". It seems the situation with netplan/networkd is "there's no option", and in NetworkManager is "there's no option, but *sometimes* it'll magically work anyway" (although you'll need to go digging in the logs to confirm that :) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1951586 Title: Need option to specify wifi regulatory domain Status in cloud-init: Invalid Status in netplan: New Status in netplan.io package in Ubuntu: Triaged Status in network-manager package in Ubuntu: New Status in netplan.io source package in Jammy: Triaged Status in network-manager source package in Jammy: New Status in netplan.io source package in Kinetic: Triaged Status in network-manager source package in Kinetic: New Bug description: It would be nice if netplan offered an option to specify the wifi regulatory domain (country code).
