Comment (by gvalkov):
Here are a few recommendations to make your script better:
If there are known stations that should always be online, use arping to
test your connection and only reset wifi if that fails.
{{{
arping -I br-lan -f -c 1 -w 1 192.168.1.101|grep "reply from" > /dev/null
||wifi
}}}
Notes:
1. With arping you can even detect hosts that have a firewall blocking
ICMP.
2. Running wifi alone should be enough to reset the interface. Usually you
don't need to disable and wait before calling wifi, and can omit them to
reduce downtime. You may want to keep them as a last change or issue a
device reboot if the wifi command fails to bring you online.
