I just got this same modem and any time I connected my One to the network it would seemingly kill the wireless signal. I had a D-Link wireless router and the TW cable modem previously and I connected fine. My old Inc2 would cause the same issue with the old setup, never sure why it did that.
Anyway, after some searching I found a solution that has worked so far, not sure why, but I changed the LAN IP from the default 192.168.0.1 to .0.2 and no more issues, worth a try.
YMMV
