- USB Wifi - probably cheap, not sure which adapters work and have suitable drivers, and SLOW since I think this may be USB 1.1
- Cable - free, since I already have one, but a bit inflexible and I really don't fancy doing the work to get it up there without cables dangling everywhere. I already have too many!
- Bridging adapter - about £12 and up, some need a separate power supply, others can get power from USB. Again I'm not sure how compatible these are with PPC macs; presumably you have to program in the wifi password etc., at least.
- Network via mains - simple but a bit pricy, around £25 for one pair of adapters.
Cable is probably the most practical choice, but I really don't fancy wiring it up, followed by network via mains. Can anyone give me any pointers?
