It looks like you still do not have your network setup correctly. I know from experience that some switches are "not very intuitive" when setting up VLANs :(

I would suggest manually configuring 1 or more devices with IP addresses appropriate to the network they *should* be in and get the network correct. Once you fix that then you should find the DHCP "just works".
