External Modem Hangs up, Computer asks to restart.

Since I've updated to 10.4.7 my internet connection using dial up unexpectedly hangs up and asks me to verify my settings and try again. Sometimes a transparent gray screen with a message box in 4 languages ask me to press and hold the power button for a few second so I can restart my MacBook.



And when I do restart my computer it gives me the following Problem Report:

    That's a kernel panic. Drivers like the USB drivers that run the external modem are outside the OS protection so if they screw up, they can take down your system. It could be a number of things that's wrong. If the modem was working fine before 10.4.7 then I would suspect that may have caused the problem. It could also be a hardware fault.



    You may be able to downgrade the drivers if they have been updated, I'm not sure. I would try to avoid using usb peripherals for internet access. You can get ADSL with an ethernet modem. In the long run, it's usually cheaper than dial-up these days.



    Did the modem come with a driver installation CD? If so, it may be worth a shot running that again.

    Thanks for the reply, well my internet connection works sometimes now but the rest of the time it just disconnects.



    I agree with you .7 probably screwed something up with my external modem I only hope that .8 will fix it, that or I hope Apple will release a patch or something for this problem!!



    My modem did not come with an installation CD. Btw my modem is an official Apple modem (just in case)



    I would also love to upgrade my internet service but I really don't have the money now, plus where I live its still expensive, perhaps one day, but for the moment I'm stuck with dial-up
