I had another Dlink router and all was working fine.  DI-624 I think it was.  I could swap files between my xp machine and win7 ultimate desktop just fine.  It went bad after 7 years so I bought the DIR-645 based in good reviews.

My desktop is wired and my laptop (xp) is wireless.  Both can get on the internet.  I can see the laptop from win 7 but cannot access it.  I cannont see the win 7 from xp.  But I can ping either from either machine.

The only thing I did different with the new router was go from WEP 128 bit to WPA.

I am at a major loss any help appreciated!!

Link>Welcome!

Link>What Firmware version is currently loaded? Found on routers web page under status.
What region are you located?

Some things to try:
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.

Link>Wireless Installation Considerations
What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or N or mixed G and N?
Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Try setting a manual channel to a open or unused channel.
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto.
Turn off WISH, and WPS under Advanced.
Try turning off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

Ensure each PC is on the same workgroup name and that you have folders shared out.

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
