Larry,

I have moved this post to the Dell Networking, Internet, Wireless Forums for better assistance.

What operating system(s) are involved?

What wireless adapters are involved?

What virus program and firewalls are you using? Is there a firewall on your wireless router?

I would first try going to the Network and Sharing Center.

Do you have more than 1 connection listed there?(Is there a local connection listed?)

Click on your connection. Look for TCP/IPv4 and TCP/IPv6 and click on properties for each. Have your settings match mine.
