My boyfriend recently has had trouble connecting to DSL with his G4 Desktop. The idiots at Comcast have come out several times and conclude each time that it is not a problem on their end but with the ethernet port in his Mac. I don't really believe they know what they are doing though, because they've all admitted they know nothing about Macs. So I brought my Powerbook G4 over and could not connect either. I did some troubleshooting on the phone with Comcast using my powerbook G4 and still nothing...no connection. And I know my ethernet port is just fine! I use my airport 99% of the time! I heard that a bad ethernet port is not an easy fix or even worth it because macs aren't easily patched like PCs and also because it is integrated with the motherboard? Is this true? Anyone have any other troubleshooting ideas? Every time either of us try to go online using both of our computers we get a pop-up saying can't find server. (Just a side note: every other application on his G4 works perfectly.) A friend told me to simply by a wireless router and try wireless as a solution (if it is in fact the ethernet port that is bad) How do I know if his G4 desktop has wireless capabilities? If not can I easily install an airport card?
