Review: Finally Getting the Full Speed I’m Paying For - I ditched my ISP’s rented modem the day I upgraded to a 1.2 Gbps plan and never looked back. The SURFboard S34 is a clean, no-nonsense DOCSIS 3.1 modem with a 2.5 Gbps Ethernet port plus a bonus 1 Gbps port for link aggregation if your router supports it. Setup took under 10 minutes (activate on Xfinity/Spectrum/Cox app or phone call), and it’s been rock-solid ever since—no random reboots, no overheating, just consistent multi-gig speeds. Pros: • Real multi-gig capability — Hits 1.4–1.8 Gbps actual download on gigabit+ plans (tested with my own speed tests) • 2.5 Gbps + 1 Gbps ports — Future-proof and perfect for bonding or separate devices • 32×8 channel bonding — Locks on strong even in crowded node areas • Cool and quiet — Stays barely warm, vents well, no loud fans • Own-your-modem savings — Paid for itself in under a year vs $14/month rental fees • Easy activation on major ISPs (Xfinity, Spectrum, Cox, Mediacom) Cons: • No built-in router/WiFi — Pure modem, so you still need your own router (most people do anyway) • Pricey upfront — Not cheap, but cheaper than renting long-term • Link aggregation needs compatible router — Not everyone can use both ports at once If you’re on a gigabit or faster plan and tired of rental fees or sluggish ISP gear, the S34 delivers exactly what it promises: fast, stable, multi-gig internet with zero drama. One of the best modem upgrades I’ve ever made—5 stars, no hesitation.
Review: Easy setup and fast. - Easy setup with Comcast and works with 2.5GB downstream and 300MB upstream package. Paired with the top end Netgear Orbi mesh system. Reliable and very fast.
