My Power Mac G5 freezes about 20 seconds after I plug in ethernet cable.

Hi,

I have exactly the same issue

Do you solve your problem ?

I have just installed a new modem in a french company. 20pcs and 5 macs works perfectly excepted a 2008 mac intel g5.

It freezes when i plug the network cable

Thanks,

Hi, G5s were discontinued in early 2006.

What OSX version is it running?

You are right

It is an 2006 mac

OS version : 10.6.6

I have two modems : an old Orange Pro modem from the french Orange FAI and a new Zyxel SB3300 modem

Zyxel modem freezes the 2006 mac when I plug the ethernet cable.

Thanks

I understand IPv6 is needed in the EU, but might try disabling in in Network prefs for a test with the Zyxel modem.

Yes, it works

Thanks to this POST

MacBooks constantly freezing after new router installed

I have ever disabled IPv6 in the router and it doesn't work

But, now, i have disabled IPv6 in Ethenet 1 , Ethernet 2 and Firewire mac settings

Thanks a lot everybody !!!

Great to hear! 🙂

Did we ever solve this Issue? is it the ISP?

I don't know if it was mentioned yet, but...

Also, turn off IPv6:

System Preferences » Network » AirPort » TCP/IP tab » Configure IPv6

Yes Turning Off IPv6 brought my Mac Back!! Well Done. I will inform my ISP
