Motorola MG8702 Cable Modem + Wi-Fi Router vs ARRIS SURFboard G36

Both are DOCSIS 3.1 modem-router combos for cable gigabit plans, but they target different buyers. The ARRIS SURFboard G36 is the stronger pick for most people: Wi-Fi 6, a 2.5 Gbps Ethernet port and 32x8 channel bonding handle gigabit tiers with headroom. The Motorola MG8702 uses older AC3200 Wi-Fi 5 and a dual-band design, so it suits smaller homes and lighter device loads. Owners of both report solid modem reliability; the G36 draws more praise for wireless throughput, while the MG8702 is often called simple to set up.

• Choose the Motorola MG8702 if you have a modest cable plan, few devices, and want a straightforward combo that covers a small home without paying for Wi-Fi 6 you won't use.
• Choose the ARRIS SURFboard G36 if you are on a gigabit or multi-gig cable tier and want Wi-Fi 6, a 2.5 Gbps port and channel bonding that keeps pace with the plan.
