Bottom Line
If you're an Xfinity Voice user seeking a multi-gig modem with phone support and want to avoid rental fees, the *Netgear CM2050V-100NAR Nighthawk* offers strong initial performance and solid speed capacity. However, be prepared for a finicky activation process and possible stability issues a few months in, along with less-than-ideal customer support.
