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 onceIf 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. ### ⭐⭐⭐⭐⭐ Good Modem *by on Reviewed in the United States 5 September 2026* Good modem so far. Setting up can be a slight challenge as it wants you to use an app to set it up from your phone and use a code from your email which I did not have access to because of the new modem, did manage to get it setup with an ethernet cable and laptop. Working fine so far, speeds are good and price is not too bad. ### ⭐⭐⭐⭐⭐ Easy setup and fast. *by on Reviewed in the United States 3 May 2026* 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. ## Frequently Bought Together - ARRIS (S34) - Cable Modem - Fast DOCSIS 3.1 Multi-Gigabit Cable Modem, for Comcast Xfinity, Cox, Spectrum & More, 2.5 Gbps Max Internet Speeds, 2 Year Warranty - (No Built-in WiFi) - Vabogu Cat 8 Ethernet Cable, 3ft Heavy Duty High Speed Internet Network Cable, 26AWG, 2000Mhz 40Gbps with Gold Plated RJ45 Connectors, Shielded for Indoor & Outdoor Use - TP-Link AXE5400 Tri-Band WiFi 6E Router (Archer AXE75)- Gigabit Wireless Internet Router, ax Router for Gaming, VPN Router, OneMesh, WPA3, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/716993358-s34-cable-modem-fast-docsis-3-1-multi-gigabit-cable](https://www.desertcart.pt/products/716993358-s34-cable-modem-fast-docsis-3-1-multi-gigabit-cable) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-29*
