Yes I reported. A tech came on 12/8, replaced the modem. He said there were some similar cases in the neighbourhood so he would suggest to check the boxes beside the street, and he said that can be done remotely (is that true?).
After the modem was replaced, I didn't notice any difference when everything works. Then on 12/10 the disconnection happened again at night. Exactly the same symptoms: modem status (lights, status in the portal) looks good, router status shows even I am still connected with an external IP address. But I was not able to connect/ping anywhere. The only thing I can do to bring the internet back is to reboot the modem. I notice that after the modem rebooted and all lights turn to normal condition, I still have to wait for couple minutes to get internet back because my router shows " Your ISP's DHCP does not function properly.". This never happened when I was with other cable internet providers that all use Rogers cable. This reminds me on the first day I hooked the Fido modem with residential gateway enabled, it's only assigned a IPv6 but not IPv4 so I could barely use it, until the next day it's fixed by itself. I guess this problem is never fixed.
I contacted Fido again last night when it happened again and another appointment was scheduled. Based on my research online, this is related to the communication between the modem and CMTS and/or some configuration issues with the CMTS. The chat agent can do nothing remotely rather than to make an appointment. I hope the next tech knows what the problem can be and resolve it. Internet is essential nowadays and such instable service is completely unacceptable.
