My Macbook has decided it doesn't want to share its wifi

by Buzz McCool / May 3, 2013 6:41 AM PDT

For the past year I've been connecting to wifi with an old macbook (running OSX 10.4.11), and sharing it with a Desktop PC (running Windows 7) via ethernet cable. Yesterday it suddenly stopped working for no apparent reason. The wifi connection is fine, and the macbook says that it's sharing it, but the PC has no connection.

I ran windows network diagnostics and it said '"Local Area Connection" doesn't have a valid IP configuration'.

I've tried rebooting the modem and using a different ethernet cable to no avail.

Smells like a PC issue.

There's not much to work with here but just last week Norton expired on a friend's PC and locked him out of the internet "just to be safe." The Local Area Connection would have to DHCP an address from the Apple so that's a lot to ask but tell me how you assign addresses.

I'm not sure,

I'm not sure, before yesterday I just turned on internet sharing on the macbook and it worked fine. That's about as far as my knowledge of this stuff goes.

I ran ipconfig /all on the PC and it said that the autoconfiguration IPv4 address starts with 169. which I've been told means that it isn't getting an IP address from the router.

But we don't have a router in this brew. That's why I asked how you assign addresses.
