Prevent your Synology router from using 2.4GHz channels above channel 11.
Problem: Some IoT devices only work on channels 1-11 (looking at you, Sesame wifi adapter)
Solution: Manually select channel <= 11
Problem: We lose all the benefits of automatic channel selection
Solution:
scp channel_fix.sh root@192.168.1.1:/root/
ssh root@192.168.1.1
chmod +x channel_fix.sh
echo "* * * * * root /bin/ash /root/channel_fix.sh" >> /etc/crontab
/usr/syno/sbin/synoservicectl --reload crond
