Every time I turn on our router and then on our MacBook, it takes like 5 minutes before I can use the internet. Why is this? We are using a MacBook with OS 10.4 and intel processor. We are connecting by airport and I could not tell you what router it is because I am in Japan and the company that is providing our internet service is Softbank and they always send you a router when you order their ADSL. We always get full reception by looking at the airport monitor thing at the top right side of the screen so I cant figure out why it takes 5 minutes before we can use the internet....?
