[SOLVED] Unable to switch wifi networks after setting active-backup

Hi all,

I recently changed my systemd-networkd configuration to bond my ethernet and wifi interfaces in active-backup mode. Since doing this I've been unable to use iwctl to switch networks after initially connecting. When attempting to connect, iwctl will show it's attempting to make the connection and around a half second later complains that there is "No station on device: wlan0" and shortly after Ill be put back onto the previous network.

Journalctl shows:

Apr 05 10:05:15 *** systemd-networkd[4303]: wlan0: Connected WiFi access point: *** (***)

Apr 05 10:05:17 *** kernel: bond0: (slave wlan0): making interface the new active one

I may be wrong in my reading, but it looks as though networkd is taking down the wlan0 interface in the middle of iwd attempting to connect to the new network, causing the connection to fail. Am I correct in my reading of this? If so, how should I connect to a new network? I'm pretty new to this so I'm not sure if this is a limitation of my setup, a mistake I'm making or a bug of sorts.

Thanks!

Re: [SOLVED] Unable to switch wifi networks after setting active-backup

Try modifying /etc/systemd/network/30-bond0-wireless.network from

[Match]
Name=wlan0

[Network]
Bond=bond0

to

[Match]
MACAddress=MAC_address_of_the_WiFi_card

[Network]
Bond=bond0

Thanks -thc. This seems to have fixed the issue I was having.
