There were no changes to the router configuration for the visitor. I have
been periodically blocking internet access for the laptops on the router (to
get boys to do homework) but taht shouldn't affect connection to the LAN,
and it's off now.

G-only

Yes. SSID broadcast is on and the laptops see it and attempt to connect to

Can't see such a setting

Yes, may have to try this or even reinstall firmware. Come to think of it I
have also been having problems with VPN which might point to a router
