Using Airport Express (AE), iBook can connect to internet, but can no longer connect to printer. Simultaneously, iMac can do both (just as iBook did until recently). Airport Utility on iBook is "unable to find any Apple wireless devices", which is ridiculous (because iBook is connected to the internet via AE). Why can iBook suddenly not see the printer over Airport Express? ---- Detailed description of problem follows ------- ** SITUATION iBook G4 14" iMac G5 2.1 GHz OS 10.5.4 AIrport Express (AE) w/Ethernet to cable modem and w/USB to printer iMac (via AE) - Wirelessly connects to internet - Wirelessly connects to printer iBook (via AE) - Wirelessly connects to internet * CANNOT wirelessly connect to printer (Although it always did until yesterday) ** BACKGROUND Trouble began after purposely discharging iBook's new battery as part of conditioning/calibrating. Afterward, iBook's Airport card came up with a self-assigned IP address, and only way to reconnect to AE (after resetting PRAM, deleting prefs, changing network settings, etc) was turning the Firewall off and back on. ** PROBLEM Thought everything was fine until I tried to print, at which time the iBook could no longer find the printer over the Airport Express. Troubleshooting with Airport Utility (v 5.4.1): - iMac: AU immediately finds the Airport Express - iBook: AU "unable to find any Apple wireless devices" Oh, really? Then how is it that the iBook is connected to the internet via an Apple wireless device?! The iBook now cannot find this printer at all. In the Print dialog, when I select "Add Printer", the printer that's USB-connected to the AE does not come up as a Bonjour printer (as it correctly does when I try this process on the iMac). ** QUESTION How can this situation arise? What setting am I missing? Did I somehow disconnect the printer myself, or did the discharged-battery condition make the iBook forget something?
