Hi,I wonder if your network driver is flaky? perhaps it could have been revived via the following regimen:
This morning, my internet DSL connection appeared dead. I restarted the network and anything else that would use any part of the network including dhcp. That didn't help. I checked the logs, found nothing wrong. I finally rebooted and that fixed the problem.
1. stop networking 2. remove network driver 3. start networking (which will reload the driver)
What sort of network card are you using? I don't see this happen with most but I have seen it with some (tlan comes to mind)
