When waking from sleep my iMac sometimes changes the IP address in the TCP/IP tab of my network settings for my Telewest broadband connection. The IP address changes and has self assigned in brackets underneath.
I have to go the connect via DHCP with manual address then back to connect via DHCP wait for a couple of seconds then the correct settings appear at which point everything continues to sail along nicely.
I've tried clicking the lock at the bottom of the network page but it doesn't appear to work. As i said it doesn't happen all the time which is what i find weird. Has anyone else had this, is it just me or is it a problem with Jaguar?
