My dad recently got a macbook air (2013, 10.8.4). I have a 2011 macbook air. My mac can connect to our home's wifi network, and so can all the other devices in our home, but his macbook can't. As in, it connects (or appears to according to the status bar), but the internet doesn't work. So I go to network diagnostics. It always ends up telling me that it's working fine, even though it always starts out by showing that the ISP conenction fails etc. Sometimes it even tells me that the network settings had changed. I restart his computer, the internet works for 1 minute, then it stops working again. I restart the router, it works for 1 minute, then stops working. I even try to access the router's ip address (to log in to the router) via his macbook, but not even that works. I have no idea what to do. Is this a problem with my router, or could it be a problem with his mac?


Any ideas? Any help is appreciated


Bear in mind that my wifi settings are the same as his (e.g. DNS), and that there are no conflicting ips as far as I know (it uses DHCP). This problem only occurrs on his macbook. Other devices (e.g. iPads, iPhones, my macbook) work.

MacBook Air, OS X Mountain Lion (10.8.4)
