Receive DHCP Lease But Can't ARP Gateway

What would be the the cause of someone to be able to receive a DHCP lease from a DHCP server/router, but then not be able to ping the gateway nor surf the internet. Basically DHCP seems to be working, but nothing else is. Can't ping the gateway, nothing in ARP, etc. In the DHCP server, I can see the MAC of the computer, IP it has, etc.

There is a layer 2+ switch between the router/dhcp server and the client's computer. Doing tagged VLANs to the router and untagged access ports to the computers.

Someone said its because DHCP broadcast is layer 2, and actual DHCP is layer 7?
