Looking at the instructions for a 2wire 2701 gateway, it appears that your router has more than one variety of LAN-side interface. There are public proxied subnets, public routed subinterfaces, and private networks. Then of course, there is the DMZ.

So, there are potentially up to three different subnets associated with the LAN side of your router. (Four if you count the DMZplus.) All of them may not be in use, though. Which of them are enabled on your router?

The gist of my previous post is that if your laptop is in one of the four subnets and your zune is in another, that may cause them to be unable to communicate.

When your laptop is connected via the wireless adapter, does it appear in any of the subnets?

What subnet does your Zune appear in when it is trying to connect or actaully acheives connection?

When your laptop is connected by the ethernet cable adapter, does it appear in a different subnet? Is this the same one as the zune appears in?

If the answer to the last two questions is yes, you need to reconfigure your router such that your laptop's wireless adapter is assigned to the same subnet as the Zune. You may have to open ports ("poke pinholes" per the language of your router's documentation) in the firewall to allow compatibility for any applicaitons you use.

Also, your router appears to support WPA, so you should be able to just turn it on and then update the settings on your laptop and on your zune. You may not want to attempt this until after you get the Zune wireless sync working though.
