I have an iBook (4 yrs old) with a wireless connection...been working well for a couple of years. My laptop received mail at 2:00AM and the next scheduled mail retrieval would not work. I assumed it was the Airport Card since my Belkin router was lit and my Airport Express was showing a green light. I checked the Airport Card...it was connected...nothing loose. SO....I decided to stop procrastining and went out yesterday and purchased a new MacBook. I set it up last night and the wireless connection is NOT working on this one either. Now...I have NO idea what to do next. I assumed (my first mistake) that because the router was lit - it is working correctly and the same for the Airport Express. Where do I begin? Even though I have set up all these connections myself, I am still pretty clueless when it comes to troubleshooting. Plus...I am pretty clueless with terminology. I would appreciate any help that anyone can give me. Thanks in advance!
