Mantas seems to be correct that I was giving you a bum steer about putting the DHCP=Yes into 25-wireless.network. I haven't used bonding before, either. So please consider advice from someone who actually knows what he/she's doing in preference to anything I suggest.
Have a look at how systemd obtains the IP address on the [presumably working] wired connection. # journalctl -b | grep DHCP May 16 15:32:47 rl-000db948364a systemd-networkd[382]: en01: DHCPv4 address 192.168.3.200/24 via 192.168.3.1 My Ethernet interface is called /en01/. I would expect your log to say it's /bond0/. Given that wireless interfaces look a lot like Ethernet interfaces, I don't see that you've done anything wrong, and maybe if you run dhcpd manually on bond0 for diagnostic purposes, you'll see a better result in your test. The other thing would be to ping the default gateway (192.168.43.1 in your log), in case ICMP to the outside world is blocked. (The router might also block ICMP pings, though. It depends on the paranoia level of the network administrator.) If you've just brought up dhcpd, it's still running, and the IP layer is down already, that suggests to me that systemd-networkd has gotten in the way. With wired interfaces, I swap the cable around all the time and systemd-networkd properly picks up the new IP configuration from DHCP. Maybe try a setup without the bond interface and see whether you can get IP working over wireless. I would expect systemd-networkd to gracefully handle DHCP configuration when you go out of range of the transmitter and return, or if you move to another SSID that's set up in wpa-supplicant. If that works, it suggests an issue with interface bonding. Another thing you might do is set up .network files for the interfaces that include a route metric of 0 for the wired (preferred) interface and 1 for the wireless: [Match] Name=en02 [Network] Description=WAN connection on en02 DHCP=yes [DHCP] RouteMetric=1 I'm using those successfully in my set-up, but the two interfaces are separate subnets. Still, I would expect it to work were they on the same subnet. I hope this helps, and I'm looking forward to learning more from what you find out and what others suggest. Bruce A.
