Probably a dumb question but here goes..

I can create vlans with a tplink switch.

What I need to do is have port 1-5 in vlan1 and 6-8 in vlan 2. The idea is to connect a router with dhcp 192.168.0.0 /24 in vlan 1

and a different router with dhcp in vlan 2 with 10.0.0.0/24

thus creating two seperate networks on one switch?

I have tried using 802.1q Vlans with all ports untagged. one vlan works but the dhcp on the other one won't.

what am I doing wrong, or is this even possible?
