With an AC1600 Wi-Fi standard, it provides decent coverage but may not be ideal for very large homes or highly congested network environments. Featuring 16x4 channel bonding, it ensures stable and efficient data transfer.

However, it only has two Ethernet ports, which might be limiting if you have multiple wired devices. The device is compact and lightweight, making it easy to place discreetly.

However, there are some drawbacks to consider.

In summary, the ARRIS G20 is well-suited for users seeking a high-performance, future-proof modem-router combo with robust security and control features.
