The problem can be solved by setting up a DLINK to work as a switch or put the same in bridge mode that can provide the link for communication between networks.

What causes network forwarding to take so long?

That slowness is caused by the loss of some packets on the network, which causes higher-level protocols like TCP or applications to time out and initiate retransmission. With another type of slowness, caused by network equipment, forwarding (whether Layer 2 [L2] or L3) is performed slowly.

Why can’t My Computer communicate with other computers on my Network?

The common problem you’ll encounter is that computer will be able to communicate with hosts on local network and to all remote networks but not to those who have same class and are nearby to it.
