No devices found on local Network

[Guest]

Both computers on my local network can access Internet....But...
They can't access each other. File Sharing is turned on in both and they are
both on the same workgroup.
I can successfully ping to the laptop which is Wireless, but not from the
Wireless to the desktop, which is Ethernet.
The desktop successfully pings the Gateway (MN-700) device.

Here's output from ipconfig /all on desktop:

This is usually caused by an overlooked or misconfigured firewall. For
instance, when you run the Network Setup Wizard it turns on the XPSP2
Windows Firewall. If you aren't running a third-party firewall or have
an antivirus with "Internet Worm Protection" (like Norton 2005/06)
which acts as a firewall, then you're fine. If you have third-party
firewall software, configure it to allow the Local Area Network traffic
as trusted. I usually do this with my firewalls with an IP range. Ex.
would be 192.168.1.0-192.168.1.254. Obviously you would substitute your
correct subnet.

From a recent post, I learned that the later nForce NIC's have a
firewall. I Googled for "nForce network adapter firewall" and found
this link that might help if you've got this hardware:
