Just my 2c worth. (This may or may not help)

Disable dhcp on your LAN.

Assign all peripherals on your LAN a static IP address. eg:
Your computer 10.1.1.30
Kids computer 10.1.1.31
"Wife's new laptop" 10.1.1.32
etc, etc, etc

Printer
10.1.1.20

Gateway
10.1.1.1

Right click on your network icon on WinXP/ Right click on wireless and ethernet/ Highlight Internet Protocol/Click properties
and configure each computer as above.
Ensure each has their own address and they use it, as well as subnet mask which is 255.255.255.0,and gateway of 10.1.1.1

You only need dhcp from your modem/router to the internet. Not neccessary in your LAN

By doing this each computer/printer etc has its own designated address. Reboot ALL computers and modem/router
Ping from each computer to gateway and each other.

See how this goes

First thing to do is ignore astina6.

You posted the WAN interface information in regard to the TPLINK whereas the LAN interface information would have been of more use. The DLINK assigns an IP address using DHCP to the WAN interface of the TPLINK, e.g., 10.1.1.2/8. This information can be ignored for the moment (/8 means 8 bit subnet or 255.0.0.0).

The LAN interface of the TPLINK needs to be on a different subnet to above (different subnet to WAN interface), e.g., 192.168.1.1/24. The computers also need to be on this 192.168.1.0/24 subnet so that they can communicate with the TPLINK via its LAN interface. These IP addresses are private and a never routed on the Internet.

Command of the day: "ipconfig /all". Please learn to use this command from the shell prompt. Run on each computer. Remember that IP address of computer may change if useing DHCP from TPLINK.

EDIT: The computer's gateway address should be the TPLINK's LAN interface address, e.g., 192.168.1.1, if using DHCP then this should be assigned by the TPLINK correctly.

If you can access the Internet and the DLINK and the TPLINK from the computers then the IP address setup is fine. Any issue with failed tracert or ping is because ping is blocked, routed elsewhere, or you are simply pinging the wrong adresss, i.e., the IP address is NOT what you think it is.

Apart from the Windows firewall do you have any 3rd party firewalls?

  Hi the WAN is on a different subnet to the LAN and the subnet on each PC is the same as that of the LAN.The IP address on the TPLINK LAN and the wireless are the same 192.168.1.1 and the default gateway on each PC is the same as well 192.168.1.1  I ran ipconfig/all on both PC and nothing changed and it all looks ok as fare as I can tell but I can still not see the other PC.  I did notice that they both had a host name, should one be a guest or doesn’t it matter?  The IP addresses are assigned automatically but there always the same and the IP addresses that I have typed in have been the right ones.No I do not have a third party firewall.

first few things...

make sure your subnet mask matches, check your workgroup name matches i.e MSHOME VS WORKGROUP won't work.
Lastly check if this works over ethernet cable, if that's fine try wireless incase that's what you want. If it fail's it could be either interference of RF's, firewall or DHCP - though you said you could ping ok, so i doubt the last one on DHCP.

Also last tip; make sure you know theres no IP address conflicts with PC's or Routers, especially if bridged.
