Every November a windstorm comes off the Pacific, a Douglas fir drops across a line somewhere in King or Snohomish County, and a few thousand people find out which kind of internet they have. Buried fiber and cable shrug it off. Aerial lines on wooden poles go down with the power. A 5G receiver in the window keeps working until the tower's battery runs out. West of the Cascades, wet-weather reliability matters when you choose.
Our pick for most Washington homes is Xfinity. It reaches more addresses than anyone else in the state with a wired cable line, the second-best technology after fiber; reach plus technology is the whole basis for that call. The upgrade, where you can get it, is CenturyLink's Quantum Fiber in Seattle and Spokane.
Which internet providers cover most of Washington?
Washington is a cable state. Cable at 100/20 Mbps reaches close to nine in ten locations, while fiber reaches fewer than four in ten.[1] Four providers reach most of the state: Xfinity, T-Mobile, Verizon 5G Home and CenturyLink.
| Provider | Type | Where it's available | Contract |
|---|---|---|---|
| Xfinity | Cable | Across most of Washington | No annual contract[2] |
| T-Mobile 5G Home Internet | 5G fixed wireless | Across most of Washington | No annual contract[3] |
| Verizon 5G Home Internet | 5G fixed wireless | Across most of Washington | No annual contract[4] |
| CenturyLink / Quantum Fiber | Fiber in some cities, older copper elsewhere | Across most of Washington | No annual contract[5] |
| AT&T Internet Air | 5G fixed wireless | In many areas | No annual contract[6] |
| Ziply Fiber | Fiber where built, older DSL elsewhere | In many areas | Not stated |
| Astound Broadband | Cable | In some areas | No contract required[7] |
Xfinity's 300 Mbps plan is $45 a month for five years for new customers on autopay and paperless billing, with unlimited data and the gateway included.[2] CenturyLink Fiber up to 500 Mbps is $50 a month where available, with no annual contract and unlimited data, plus a CTL fee of up to $1.50 a month.[5] Astound's promo is $40 a month for twelve months with autopay.[7] Spectrum serves a few pockets. Satellite from Starlink, Hughesnet and Viasat is available almost everywhere and is the fallback for cabins and islands; Starlink starts at $55 a month.[8]
What is the best internet in Seattle, Tacoma and Vancouver?
Seattle is the fiber exception. More than three-quarters of city addresses can get fiber, mainly CenturyLink's Quantum Fiber, and Xfinity cable is on nearly every block.[1] For people searching fiber internet providers in Seattle: if your street has the fiber, it is the better product, with CenturyLink at $50 for up to 500 Mbps versus Xfinity's 300 Mbps at $45.[5][2] Seattle also has the strongest 5G coverage in the state.
Spokane is the other fiber city. Fiber reaches about six in ten homes, split between Ziply Fiber and CenturyLink, and Xfinity is nearly universal. Anyone looking for cheap internet in Spokane should compare Xfinity's five-year rate against whatever Ziply quotes, since we could not retrieve Ziply's terms.
Tacoma is a mixed city: fiber on roughly four in ten streets, Xfinity nearly everywhere. The best internet provider in Tacoma for most households is Xfinity, with T-Mobile the main rival.
Vancouver and Bellevue are cable-first. Fiber reaches fewer than four in ten homes in each, so the real contest is Xfinity versus 5G. Kent is the most cable-dependent big city, with fiber on barely one in ten streets, so the best internet provider in Kent is Xfinity unless a T-Mobile or Verizon signal tests well at your window.
Is 5G home internet a good choice in Washington?
Along I-5, yes. Licensed fixed wireless at 100/20 Mbps reaches nearly half of Washington locations, a higher share than fiber.[1] T-Mobile is headquartered in Bellevue, and its Rely plan is $50 a month with AutoPay, unlimited data and no annual contract.[3] Verizon 5G Home is $35 a month with a Verizon phone plan and has no annual contract or equipment charges.[4] AT&T has no fiber in Washington; its offer is AT&T Internet Air, with unlimited data and no annual contract.[6]
Treat 5G as a strong second choice in Seattle, Bellevue, Tacoma and Spokane, and as the first choice for renters who move often. Over the passes, check the signal before you commit; the fixed-wireless map thins out fast east of Ellensburg.
Which internet holds up best in a Pacific Northwest storm?
Ask how the line reaches your house. Newer subdivisions in Snohomish, Pierce and Clark counties often have buried utilities, and buried cable or fiber rarely goes down in wind. Older neighborhoods on poles lose cable when a limb takes out the strand. Fiber and cable both need power at your house, so a small battery backup for the modem is cheap insurance.
5G home internet runs on the carrier's towers, which have backup power, though not unlimited. A 5G gateway on a small battery can keep a household online for hours after the neighborhood goes dark, a decent argument for a 5G second line if you work from home in the foothills.
What should I ask before I sign up?
- How long does the price last? Xfinity's $45 is a five-year rate; Astound's $40 runs twelve months.[2][7]
- Is there a contract? Xfinity, CenturyLink, T-Mobile, Verizon and Astound all say no.[2][5][3][4][7]
- Is data unlimited? Yes on Xfinity, CenturyLink, T-Mobile and AT&T Internet Air.[2][5][3][6]
- What fees are added? CenturyLink adds a CTL fee of up to $1.50 a month.[5]
- Is the line to the house buried or aerial, and how soon can the install happen?
- What happens at renewal?
