Hi, I have encountered the following problem several times. I connect my mac to a wifi network. The login is ok and I can see the signal strength, however the internet does not work. Strange thing my iphone is also connected to the network and internet works fine. So I look at the preferences in both machines and note that the ip addresses are very different ie. 192.168.1.x and 169.172.1.x. I then go to the mac and set a manual address (the ip, the dns, etc.) from the iphone and apply these settings. At this point the mac is ok to use the internet. Why is it the iphone can automatically find the correct settings whilst the mac cannot? Any ideas welcome ?
