My daughter's MacBook Air used to work seamlessly on our home wireless network--until today. Her machine runs OS X 10.5.8.
Her laptop has been very straightforward, very plug and play.
Today, it stopped connecting to the internet, completely. The AirPort connects to the wireless router as normal. It sees the router at full strength and is logged in with the proper password.
But it can't connect via Google Chrome, Safari, e-mail -- anything.
Trying a direct ethernet connection is no help either--it keeps telling me the network cable is not plugged in.
But the cable is fine, and it works on other machines. And this computer I'm using to write this, my work PC laptop, is logged in via the same wireless just fine.
We tried rebooting the Mac, the modem, the router. No change.
Under Network Preferences, everything looks OK on the intro page. There is one message that looks benign: AirPort has a self-assigned IP address and may not be able to connect to the Internet". Correct me if I'm wrong, but I believe that is the usual message on this page.
The "Assist Me" screen gets stuck at "please restart the device", the device being the modem and router. As I said, these are fine on other computers. I restarted them all anyway, but it made no difference and I'm stuck in this loop.
Summing up: Airport is seeing the router and has the password, but it can't connect to the ISP. The MacBook won't connect via a physical cable, either.
Stumped. I can't understand what's going on because guest machines brought in from outside and two other computers in the house have no problems. They need no special login to the ISP, just the router login, and that part is working fine.
It could be a settings problem, I guess, but I see no reason why they would have been wiped and everything looks OK, it's all set to obtain an IP address automatically. Tried some other threads here but none I could find matched my symptoms. They talked about trashing certain files under /library/preferences/systemconfiguration/etc...., but that path does not exist on the machine in question.
