Things that comes to my mind: 
* I had a mobo w/ a funny onboard ethernet I/F: after "some" networking, it
  needed a linux driver reload (or w$ reboot) - never knew why,
* a MiM missed attack could also give this result (cli should watch arp),
* Even though I'm downtown the renewal of my adsl box lease takes almost 4
  minutes to "stabilize".
