The AirPort Utility software for 9 and X doesn't seem to offer a port speed selection option. If it is there, I've never been able to find it in Mac OS 9.2.2, X 10.1, or X 10.3 (my Jaguar install CDs died and so I can't see if Jaguar offers that.) It's miraculous that the IIci will work with a standard one of these things. If I was to put System 7 on the IIci, then it would be more stressed and that's what's got me running System 6 as I'm not interested in speed so much as stress, but if I can get the IIci's hard drive with a stable System 7.0.1 install that might just go a whole lot better. The only thing other than stress that makes it inconvenient is my Power Mac G4 Quicksilver I use to load a full OS onto the IIci (that's how I got System 6 on there) when I install the 80MB hard drive with System 7 the Quicksilver will try to boot from the 80MB SCSI hard disk instead of the startup disk selected in the Control Panel and there's no way to bypass it. Which means that once I put System 7 on the IIci I can't make any other changes.

I wish I knew how to force the LAN port on the AirPort to go to 10baseT half duplex because your reply has been so very helpful. I'd be more enthusiastic, but I'd get in trouble
