It seems to be DHCP in Waterloo/Kitchener but not official yet. Still looking into it.
That was my experience as well - though on Sunday. Was unable to get an IP address (timeout on DHCP request). Modem DS/US was fine. It's as if the DHCP server was down/out of IP addresses/decided to ignore a particular modem MAC for a while (changing the router's MAC didn't help).
Waiting an hour and performing a hard reset (with the reset button) seemed to fix it. Might just be that there were free IP addresses at the instant I reset, or might just be that the DHCP/Modem finally started talking nice again.
Yeah, repeatedly... Mine was one of the last ones to come back during the previous outage too... I'll give it 'til morning then hit the direct forum. Thank goodness for having a backup connection (hurrah for working for an ISP that does DSL!)
