Here's the deal... Cable internet, Airport connected to the cable internet through an ethernet cable. Two computers. One G5 iMac, one G4 iBook. The G5 iMac connects to the internet, iTunes, software update, etc. with no problems. The iBook won't connect to iTunes or software update, but can still connect to internet when using Firefox. But not always with Safari. What gives? Never had this issue before... Thanks in advance!!
