te25, the problem is usually that you have multiple NICs (Network Interface Cards) on your PC, and your wireless one has priority. Winsock (Win7) controls access to your NICs. NetEdit cannot do this (nor any other software). So, you can try to reprioritize your NICs:
1. Start --> Control Panel.
2. Select "Network and Intranet" at the top.
3. Double-click on the "Network & Sharing Center" icon.
4. Press the <ALT> key to make a menu appear at the top of this window.
5. On the menu at the top, select Advanced --> Advanced Settings...
6. On the "Adapters and Bindings" tab, in the top window, select the connection you are using.
7. Use the green arrows at the right to move this connection to the top of the list.
8. Press <OK> and close Network Connections window.
9. You may have to reboot your PC.
