As my G4 does not have an airport I will have to find an alternative way to connect it to the internet.

A few methods come to mind.

1. Devolo plugs to router then to ethernet on G4 but never tried power plug networking and costly at £40 for two plugs not including cat 5 leads.

2. Internet Bridging via dedicated bridge. Once again quite costly but guaranteed speed once again connecting to ethernet.

3. Cross over cable from laptop or G5 sitting next to machine. Cheap but probably a nightmare to set up.

Any other suggestions on how I could do this?
