I an using openwrt 22.03.2 with mwan3.
When powering on or rebooting openwrt it seemed to get rather lost, which could be corrected by maually restarting the network followed by restarting mwan3.
Looking at the log it seem that some wan interfaces were attempting to connect before the system was ready i.e before br-lan was up.
To try an work around this I set wanb and wanb6 to 'Not started on boot' and added this to /etc/rc.local
\# wanb6 seems to need something extra running before it will start cleanly.
\# it seems to start best if is ready to go as wanb connects. Hence wanb6 than wanb
( sleep 30
Can you suggest a better solution?
Is this a common problem?
