Have you tried simply running the Network Connection Wizard from control panel? Here is a link to
a basic guide. I'm not sure I understand whether there's an issue with the connecting computer or if you want to set up a host/client shared connection. If the latter see
here. Does
this apply to your situation?
Take a look at
this post, and also see the FAQ sections of the same site for endless help.
You can also access 2wire tech support
here.
If you think there may be some corruption in the 2nd computer, run chkdsk according to instructions
here and
here.
You might also have a look in the Device Manager and make sure the network adapter is working properly. It will show an exclamation point or question mark if it's having problems.
Your connection is behind the 2wire firewall, which should be turned on. If you mean your system firewall, OK for now...
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
