Have a feeling default routes are set elsewhere these days

Lemme see in Mi Pi...

Ah yes. Imn /etc/dhcpcd.conf

there will be a line saying

static routers=192.168.1.254 or whatever.

Make sure it is.

Pis tend to use dhcp and te easy way to static them is to frig with dhcp
- but these Pis might hacve decided to 'renew their leases'

And also make sure that the router* isnt advertising a bad gateway

*or some other dhcp master on the LAN
