Walmart offers the refurbished Netgear CM500 DOCSIS 3.0 Cable Modem for $29.99. Choose in-store pickup to avoid the $5.99 shipping fee. That’s $15 under our mention from last month of a new unit and the lowest price we’ve seen. (It’s $15 less than the best deal for a new unit today.)
It supports 16 download and four upload channels with speeds up to 680MB/s. It’s certified for Comcast Xfinity, Time Warner Cable, Cox, and Charter, among others.
