First, I should explain why we're trying to keep a Flowerpot iMac on the road when we have other Macs. My DH has early-onset Alzheimers and has meltdowns if we even discuss learning a new web authoring program. He can use ClarisHome Page in his sleep but he can't manage the simple CSS scenario I developed or even make easy changes to a custom-made iWeb template. His website is extremely important to him, we think it provides a sense of continuity with as more vibrant past. A few months ago the Flowerpot's Airport connection just stopped. I'm in poor health too and wasn't able to troubleshoot so I just setup simple internet sharing with an Ethernet cable from his newer iMac. Last night this connection stopped and we can find no reason for either failure. We tried deleting and re-creating the Airport and device plist files and swapped out ethernet cables. We also rebuilt Permissions on both Macs, Restarted multiple times, and tried Networking Assistant and Diagnostics. I am a former Apple IT Specialist and have usually find relief in these measures.
The Flowerpot can see all area wireless networks except our own, routed via a Time Capsule. It fails to detect a wide open Guest network made just for it as weill as our two (5 GHz and 2 GHz). Nothing in our setup changed around the time of either failure. I also tried a Wireless USB adapter which also failed to see our LAN. The Flowerpot is driving 10.5-something and the other iMac is running Snow Leopard. both disks pass in Disk Utility. We do have Ethernet file sharing but no Internet on the Flowerpot. He has to make his changes in HomePage then copy those files to the newer iMac for uploading via an ftp client. It's slow-going, and I'd love to give him back his internet if there's any possible way. We're wondering if there's another file that might be corrupt or hardware that could be failing.
Thank you for your kind help.
