said by TSI Jonathan: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.
