netplan config at
/etc/netplan/wireless.yaml seems to be working well for my WiFi-to-USB adapter, but I seem to still get the native interface to come up. I would prefer to keep that down. Right now,
sudo ifconfig wlp0s20f3 down doesn't seem to be persisting across reboots with config:
# See also: https://netplan.io/reference network: version: 2 renderer: networkd wifis: wlx7ca7b0babcf7: dhcp4: yes dhcp6: no addresses: [192.168.7.12/24] gateway4: 192.168.7.1 nameservers: addresses: [18.104.22.168, 22.214.171.124] access-points: "my_network": password: "my_password"
How can I adjust my netplan config to keep the native WiFi interface down? Is that something that can only be configured to be persistently off elsewhere?
$ cat /etc/network/interfaces # ifupdown has been replaced by netplan(5) on this system. See # /etc/netplan for current configuration. # To re-enable ifupdown on this system, you can run: # sudo apt install ifupdown
Note I have a LAN I connect to:

wlx7ca7b0babcf7is what I want up while the other native interface
wlp0s20f3is what I want down.
