Best Internet Services Available in
seattle, Washington
Seattle’s broadband market is mature and competitive: most households can choose between high-capacity cable, growing fiber, 5G home-internet, and satellite options. Cable (Comcast Xfinity) remains the most widely available option and offers the highest advertised cable speeds in the area for many addresses — good for heavy streaming and multi-user homes. Fiber and fiber-powered networks (Astound/Wave, CenturyLink/Lumen and regional fiber operators such as Ziply) are increasingly available in neighborhoods across the city and deliver the most consistent upload speeds and lower latency — a better choice for creators, streamers and gamers where it’s offered. 5G home services (T-Mobile, Verizon) are a convenient, no-contract alternative in many Seattle ZIP codes and typically deliver hundreds of megabits per second in real conditions. Satellite options (Starlink) fill gaps outside wired networks or for users who want a simple install and wide availability. Because availability and pricing vary block-by-block, always run an address-level check; plan tiers and promotions change often, and Lumen’s consumer fiber assets are being acquired by AT&T which may reshuffle local offerings and pricing in 2025–2026.
| Provider | Primary technology | Typical top advertised speeds (city listings) | Quick note |
|---|---|---|---|
| Comcast Xfinity | Cable | Up to ~1.2 Gbps (consumer tiers vary by address). | Widest cable footprint in Seattle neighborhoods; promotions and bundle options common. |
| Astound (Wave) | Fiber-powered / cable | Plans up to ~940 Mbps (fiber/fast cable tiers). | Strong regional provider in Puget Sound with competitive pricing and no-contract options in many areas. |
| CenturyLink / Lumen | Fiber (where built) & DSL | Fiber up to ~940 Mbps in covered areas. | Fiber expansion in select neighborhoods; availability must be address-checked. (Note: Lumen’s consumer fiber was announced for sale to AT&T — see news). |
| Ziply Fiber | Fiber | Symmetrical fiber plans (varies by address; check availability). | Regional Northwest fiber operator expanding into new neighborhoods — sign up for local availability alerts. |
| T-Mobile Home Internet (5G) | Fixed wireless (5G) | Real-world ranges commonly ~133–415 Mbps (varies by location/time). | No-contract, easy install — good fallback where wired options are limited. Run an address check for exact speeds. |
