Hi - I am a non-technical person here out of desperation!
I have an iMac G5 (OS X 10.4) and I access the internet using Rogers cable highspeed Internet. Up until 24 hours ago all was hunky dory. Now though when I connect, my internet access freezes up within a few minutes. Initially, the only way I could reconnect was by restarting the computer. Now I have discovered that I can renew the DHCP lease to reconnect.
To resolve the problem I have tried disconnecting and reconnecting the ethernet cable and the power going to the external modem. Likewise the computer itself. I also scanned for viruses or spyware that could potentially interfere with the Mac but came up with a clean machine.
Any ideas why my connection would suddenly stop? Isn't the Mac supposed to renew the DHCP automatically?
Thanks in advance for any clues you may be able to provide! Richard.
