I'm running a TiPB 500 with an airport (original/slow), at least I have been. The System Preferences shows the card and it's powered up, but the card no longer detects my or the other neighbors wifi networks. I've confirmed that my wifi network is still running fine with another device. I'm going to do a clean install of OS 10.411 to see if something went wrong with the software, as we all know sometimes happens. It's probably slightly over due for this maintenance, though I hate to do it. The card has been working great for years.
I can't get the original hardware test disk to run in OS 9.2 (start up holding down the "C" key) for some reason, so I can't check the card that way.
If the clean OS install doesn't fix things, I'll want get a replacement wireless network card for this machine. The choices seem to be another Airport card off of ebay ($10, and reasonable) or upgrade to a better way with a pcmcia WiFi card like a Linksys dual channel N card off of ebay for ($15, also very reasonable).
I'd like the convenience of the built-in device, the old Airport card. However, I'd like the advanced speed of the dual N channel WiFi. But I can't find any Mac drivers on the Cisco/Linksys site for the card I looked at, the WPC600N. Will OS 10.411 automatically recognize it? Thanks for any advice.
