Recently I obtained an iMac G4. It has a 1 GHz CPU, 1.25 GB of RAM, and is running on Mac OSX 10.5.8. I have no options for a hardline and I don't necessarily want to buy a wireless card. In my efforts to get my G4 on the internet, I used an ethernet cord to tether it to my Macbook Pro (Mid-2010). I went into system preferences, then to "sharing." These are the setting currently set up for the Macbook Pro: These are the setting currently set up for the iMac G4: From the settings, it should work. When I open networking on activity monitor on my G4 there is data being received and sent. There are times that my iMac will get on the internet and other times I just get error screens. Is there an extra step that I'm missing? Please help.
