I am trying to set up a wireless access point on my raspberry pi 3B (running Ubuntu 18.04 server) using netplan. The documentation seems to imply that I can do this by specifying mode: ap in the .yaml configuration file for netplan (located in /etc/netplan folder). However, when trying to apply the netplan, I get the following error: wlan0: netowrkd does not support wifi in access point mode. I know for a fact that the adapter itself supports AP mode, since I've successfully used it before using a slightly different procedure that involved purging netplan and using hostapd directly. I would like to stick with netplan this time because this way I can easily switch between AP and managed modes by switching out the .yaml file. Is there any way I can get past this error?


As documented in netplan(5):

ap is only supported with NetworkManager.

You must specify renderer: NetworkManager and install the network-manager package to put a wifi interface in ap mode with netplan, because as stated, this is not implemented with the networkd backend.

  • Yep, thank you. Just found that solution. – anvoice May 9 at 22:11
