iTunes Quitting Internet Connection & More ...

[Henri Gaudier]

We've finally bought an iPOD and so we've started to build up a library of CD's on our Mac but we've encountered quite a few problems and so we wondered if there were any work-arounds. The most serious is the machine keeps freezing and bringing up a window that the only time I'd seen previously was when my iBook's logic board had died. The message is a black oblong in which it says that it's necessary to restart the machine by holding down the power button. At the same time the screen dims. This happens after inserting a CD.

Also this morning -

Everytime we insert a disc the internet quits. (We're on dial-up) Not only is it laborious I'm starting to worry. Before all of this the machine was fine. Now there are freezes and what appears to be kernal panic messages. (Something that I'd only previously read about and never understood as I'd never encountered them/it.) I'm using the latest software. Help.

The panic log clearly points at an issue with either the modem hardware or driver. It appears you are using some sort of Motorola 56k USB modem. Is this an external modem? Or are you using the internal modem (which could be on an internal USB connection)?

 

[Henri Gaudier]

It's Apple's own USB modem. The internal was fried in a thunderstorm.

 

[robbieduncan]

Do you have any other modem you could try with? Or even an old Airport basestation with a modem in it?

 

[Henri Gaudier]

Hello Robbie, No I don't. Why? Do you think the replacement modem is faulty? Since the switch from internal to USB we have had a lot of "modem has unexpectedly quit" messages but only ever having had dial-up I've seen them a lot over the years. But the latest glut definitely started at the time of the switch over. I didn't put much store by it because I was thankful that I was back on-line and the internet service is crap anyway.

Thanks for sticking with the thread but I'll be absent soon as I'll be watching the FA Cup this afternoon.

Could be the modem, the cable, the port...
