In the last four to six days the wireless on my network kept failing (particularly overnight - but that may be less to do with time of day and more to do with lease expiry??). I searched and found that someone else resolved this back in around 2018 by enabling IGMP Snooping and then rebooting their router (https://forum.openwrt.org/t/wifi-up-device-connected-but-no-internet/) - That worked for me but only temporarily. This morning, even though (on LuCI and via SSH) I can see IGMP Snooping is still enabled (LAN interface), the same problem occurred - all the wireless devices can connect to the router but not the Internet. For the moment, rebooting the router fixed it but clearly that's not a realistic solution.
I have marked this high severity because:
It looks like a regression
My kids can't access school via their iPads and are getting marked absent! (like many/most, we're in lockdown)
config interface 'lan'
option type 'bridge'
option ifname 'eth0.1'

option broadcast '192.168.7.255'
option ipaddr '192.168.7.1'
option gateway '****' <- my WAN static IP
list dns '1.1.1.1'
option igmp_snooping '1' <- I set this, which seemed to resolve it, but only for a bit
[In other news, another reboot - along with setting the option igmp_snooping '1' seems to have fixed it and be stable for the last couple of days (fingers crossed)]
