What customers say
This modem earns praise primarily for its robust performance and speed capabilities, especially for gigabit subscribers utilizing the 2.5 Gbps port. Setup is generally straightforward with major compatible internet service providers. Power users value the bandwidth stability it offers for demanding activities like streaming. However, a key concern involves ISP compatibility and provisioning, as some users face frustrating activation delays or firmware issues with certain regional providers. While performance often justifies the premium price, a few reports suggest potential long term reliability concerns regarding device longevity. Buyers should confirm ISP compatibility before committing to this high performance modem.
