I have an iMac and my MacBook Pro is unable to connect to it through internet sharing.
Is there a way I can check whether my wireless card is working, or diagnose the problem in more depth? I have already tried the usual stuff: from re-creating the connection to wiping the PRAM.
How do you want to "connect"?
I want to share my iMacs internet connection.
What kind of connection are you even creating?
A straight forward Wifi connection using 128 WEP
Do you have shared folders that you want to access?
No
What IP addresses to the machines have?
the MacBook Pro is unable to attain an ip from the iMac, though it can see it.
Can the Macs ping each other via IP?
No
