Yes, and it's by far the worst thing about it. Reset your router while there's a cable outage? Sorry, no wifi until your cable company gets the internet connection back online.
This hit me when I moved recently. I would usually fall back to just accessing the configuration on my phone's cell connection, but 1) the house I moved to has poor reception for my carrier and 2) the cable enters the house in the basement so even less signal. Cue several rounds of climbing up and down the stairs.
