Question : Problem: Using Internal Airport to Share Ethernet Connection

My apple macbook pro running leopard is connected to the internet via ethernet. I have permissioned Internet Sharing for the internal airport card.

Airport Options are set to:
Channel: Automatic
Encryption: Enable
Password: 5 hex characters e.g. 123AB
WEP Key Length: 40bit - more compatible

Vista says:

Windows cannot connect to "MyMac"

When I click on "View the wireless security settings on this computer to verify they are compatible with this network" - nothing happens.

How can I get vista to connect to the wirless network.

PS My iphone can see and connect to the network

Answer : Problem: Using Internal Airport to Share Ethernet Connection

Your settings for sharing the Wireless Connection do not look quite right.

1st step .. ALWAYS start with all security WEP etc. DISABLED.  To establish the connection (you can add security later) you should first try without any encryption.

2nd .. Disable any Firewalls or security software on Vista and OSX.

3rd Start with a static IP scenario. Remember that the Mac will be acting as a type of DNS server which may not be to the liking of Vista. To begin with assign fixed IPs .. Using the same method as described here

4th .. Assuming you get it running you can then try using dynamic IPs if you want, selectively re-enable the firewalls and finally adding encryption.
