C7100V Verified Purchase Reviews

Great Cable Modem RouterThis is a 5 Star cable modem router for internet and voice.6 Months Ago – Tony D. via Best Buy C7100V★★★★★
The ABSOLUTE BEST solution for Comcast I’ll make this short and to the point: if you have Comcast as your provider, and you have their Triple Play plan (TV, data, and voice), this is hands down the BEST solution available. Netgear is the king. Highly efficient, great GUI, incredibly secure, and dependable. The other options are Arris and Motorola. Neither of them is half as good as Netgear!
