explains the Code 10 error. Probably driver
-related, especially if you upgraded to Windows 7 on your existing computer. I personally never even use my ethernet... and as for the 'Sharing' tab not showing up, the Xbox tutorial mentions that:
If you don’t have a Sharing
tab, it means:
- Your computer doesn’t have two network cards.
- You’re trying to share a network connection that can’t be shared. Repeat step 3 with a different network connection.
We can rule out the first one because you obviously have wireless and ethernet. And if you have admin access to the wireless network, I'm pretty sure you can enable sharing. But if you're mooching free WiFi off the neighbors like I used to do in college, you might be outta luck :/ Hopefully a network pro will stumble upon our little thread here and offer some deeper insight.
