Broadband in 78217 is unusually competitive for a San Antonio ZIP code. Current provider records show a major fiber-versus-cable comparison: Google Fiber has a large reported fiber footprint, AT&T specifically identifies Windcrest and ZIP 78217 for fiber service, and Spectrum maintains a near-ZIP-wide cable network. T-Mobile and Verizon also add substantial fixed-wireless alternatives.

78217 is not simply a cable market with a limited fiber overlay. Current ZIP-level records show multiple large fiber networks alongside extensive Spectrum cable service and substantial fixed-wireless coverage. The most significant local comparison is between Google Fiber, AT&T Fiber and Spectrum, with wireless providers adding another layer of competition.
Current ZIP-level broadband data report Google Fiber fiber coverage across a large majority of 78217. Google Fiber's own Texas service information also specifically lists Windcrest among its San Antonio service areas. The address checker remains necessary because the reported ZIP footprint is not a property-level guarantee.
AT&T's San Antonio area-code information identifies Windcrest and ZIP 78217 with fiber service up to 5 GIG. Current ZIP-level datasets report AT&T Fiber across a substantial portion of the ZIP, creating a meaningful second fiber network rather than a single-fiber-provider market.
Current ZIP-level records report Spectrum cable availability across almost all of 78217. The reported cable footprint makes Spectrum the primary wired alternative where Google Fiber or AT&T Fiber is not available, and it can also compete directly with fiber where networks overlap.
The table separates provider evidence reported for the ZIP from address-level ordering information. FCC-derived datasets are useful for understanding the local market, but the FCC broadband map itself is designed to show provider-reported availability at specific locations.

The provider descriptions below focus on networks with meaningful current evidence in or specifically associated with ZIP 78217. Smaller reported footprints are separated from the major wired networks.
Google Fiber is one of the defining features of the 78217 broadband market. Current ZIP-level data report a large fiber footprint, and Google's own Texas service-area information specifically lists Windcrest as one of its San Antonio locations. That combination makes Google Fiber materially more relevant to 78217 research than a generic citywide provider listing would suggest.
AT&T has unusually direct local evidence for 78217. Its San Antonio area-code information specifically identifies Windcrest and lists ZIP 78217 alongside fiber service up to 5 GIG. Current ZIP-level datasets also report a substantial AT&T Fiber footprint in the ZIP.
Spectrum remains the broadest cable network reported in 78217. Current ZIP-level records place Spectrum cable coverage at approximately 99.65% of the ZIP, making it the most geographically extensive wired network in the dataset. That does not make Spectrum the only practical choice: much of the ZIP also has reported fiber competition.
T-Mobile is a meaningful part of the 78217 broadband market because current ZIP-level records report fixed-wireless coverage across most of the ZIP. Unlike fiber or cable, T-Mobile Home Internet does not require a wired drop to the home, but eligibility can change with network capacity and the radio conditions at the property.
Verizon provides another substantial fixed-wireless alternative in 78217. Current ZIP-level broadband data report Verizon fixed-wireless coverage across a large majority of the ZIP. Verizon therefore belongs in the local comparison even though its network model is different from Google Fiber, AT&T Fiber and Spectrum.
Astound Broadband appears in current 78217 provider datasets, but its reported residential footprint is much smaller than Spectrum, Google Fiber or AT&T. That makes Astound relevant to particular properties rather than a default ZIP-wide choice.
Hotwire Communications appears in current 78217 fiber records at a substantially smaller footprint than Google Fiber or AT&T. A provider with limited fiber coverage can be particularly relevant to a specific apartment, condominium or planned development without being a meaningful option for the surrounding streets.
Satellite services remain geographically relevant throughout 78217. They do not depend on the same neighborhood fiber and cable plant as terrestrial networks, although the ZIP's strong wired competition means satellite is more useful as a distinct technology option than as the central feature of the local market.
The important speed comparison in 78217 is not simply whether a provider advertises gigabit service. Google Fiber and AT&T offer multi-gig fiber where available, while Spectrum provides extensive gigabit-class cable coverage and fixed-wireless providers offer a different performance model.
Suitable for ordinary browsing, video calls, streaming and moderate household use when the connection is stable.
Useful for households with several simultaneous users, multiple streaming devices and larger downloads.
Relevant for larger households and substantial downloads when a fiber or high-capacity wired plan is available at the property.
Google Fiber advertises plans up to 8 Gbps in San Antonio, while AT&T advertises up to 5 Gbps where available. These tiers require the appropriate fiber service and compatible equipment.
78217 is notable because several technologies coexist at substantial scale. Fiber is unusually important in the ZIP, while Spectrum provides broad cable coverage and wireless networks add another layer of competition.
Google Fiber and AT&T Fiber are the two most significant fiber networks identified in current 78217 research. Google Fiber reports Windcrest as a San Antonio service area, while AT&T specifically identifies Windcrest and ZIP 78217 with fiber service.
Spectrum has an exceptionally broad cable footprint in 78217. Current ZIP-level records report cable coverage across almost the entire ZIP, making Spectrum the principal cable alternative where fiber is absent or where a household chooses between technologies.
T-Mobile and Verizon both have substantial fixed-wireless footprints reported in 78217. Wireless can provide another option when a property does not have the desired wired network, but eligibility and performance depend on the exact location and network capacity.
Satellite remains geographically available independent of local fiber and cable construction. In 78217 it is generally a different technology option rather than the primary competitive story because wired coverage is extensive.
ZIP 78217 covers parts of northeast San Antonio and includes Windcrest and established residential areas around the Perrin Beitel, Nacogdoches and Walzem corridors. The ZIP's combination of older neighborhoods, townhomes, apartments and newer development helps explain why provider availability can differ at the property level.
AT&T's official San Antonio area-code information lists Windcrest with ZIP 78217 and identifies fiber service up to 5 GIG. Google Fiber's official Texas service-area page also lists Windcrest as a San Antonio service area. This makes the Windcrest portion of 78217 particularly important when comparing fiber options.
Current ZIP-level broadband records report Google Fiber across a large majority of 78217. That is materially different from a ZIP where one fiber provider has only a small scattered footprint. Residents with Google Fiber and AT&T Fiber at the same address can potentially compare two fiber networks rather than fiber against cable alone.
Current ZIP-level records report Spectrum cable coverage of about 99.65% in 78217. That gives Spectrum a geographic advantage even though fiber networks reach a large share of the same ZIP. For residents, the meaningful question is therefore not whether Spectrum serves 78217, but whether the property has fiber alternatives as well.
Current ZIP-level datasets report T-Mobile fixed wireless across about 96.6% of 78217 and Verizon fixed wireless across about 94.3%. These figures do not mean every household can order both services, but they show that wireless competition is significant enough to be part of a normal provider check rather than a last-resort category.
78217 contains established residential neighborhoods as well as townhomes, apartments and newer construction. Fiber drops, interior wiring, existing conduit and building-specific provider arrangements can therefore differ from one property to another. A nearby house is not necessarily a reliable proxy for an apartment or townhome.
The northeastern San Antonio portion represented by 78217 is not isolated from the broader city's fiber expansion. Current provider records show multiple wired and wireless technologies overlapping in the ZIP. This means address-level research is more useful here than relying on a single provider's citywide availability statement.
The following findings describe what the current evidence means for residents rather than simply listing provider names.
| Finding | Evidence | What it means for a 78217 address |
|---|---|---|
| Google Fiber | Current ZIP-level records report a large Google Fiber footprint; Google lists Windcrest among its San Antonio service areas | Fiber should be checked first rather than assuming Spectrum is the only major wired option. |
| AT&T Fiber | AT&T specifically identifies Windcrest and ZIP 78217 with fiber up to 5 GIG | AT&T should be evaluated as a fiber provider, not simply as a legacy DSL provider. |
| Spectrum cable | Current ZIP-level records report approximately 99.65% cable coverage | Spectrum is the dominant cable network and is relevant at most 78217 addresses. |
| Fiber competition | Google Fiber and AT&T Fiber both have substantial reported footprints | Some properties may have a choice between two fiber networks as well as Spectrum. |
| T-Mobile Home Internet | Current ZIP-level data report approximately 96.6% fixed-wireless coverage | 5G Home Internet is a meaningful local alternative, although live eligibility remains address dependent. |
| Verizon 5G | Current ZIP-level records report approximately 94.3% fixed-wireless coverage | Verizon is worth checking separately rather than treating all wireless networks as interchangeable. |
| Small fiber networks | Hotwire and Astound appear in smaller reported footprints | Some buildings or developments may have provider choices that are not representative of surrounding streets. |
| Housing differences | 78217 includes established neighborhoods, townhomes, apartments and newer construction | Building infrastructure and provider arrangements can materially affect the final service list. |
These locations are useful reference points for understanding the geography represented by the ZIP. They are not substitutes for an address-level broadband check.
Nearby ZIP codes can have different fiber and cable footprints. Use them as separate research areas rather than transferring 78217 availability assumptions across ZIP boundaries.
The correct sequence is to use ZIP-level research to identify the relevant network choices, then verify the exact property with each provider before comparing plans.
FCC-derived datasets are useful for understanding the provider mix in 78217. The FCC National Broadband Map can then be used to examine the providers reported at a specific location. Provider address checkers remain the appropriate source for live ordering eligibility, current plan availability and current pricing.
The local network mix makes it useful to compare technology and property-level availability before focusing on the largest advertised download number.
78217 is unusual because Google Fiber and AT&T Fiber both have substantial reported footprints. If both are available at the same address, compare upload capacity, pricing, equipment and plan terms instead of treating fiber as a single category.
Spectrum's broad cable network gives it strong geographic reach in 78217, but current ZIP-level records report substantially lower cable upload capacity than the symmetrical fiber plans offered by Google Fiber and AT&T where available.
T-Mobile and Verizon both have substantial reported fixed-wireless footprints in 78217. Wireless can be useful as an alternative or backup, but eligibility and actual performance depend on the property rather than the ZIP alone.
ZIP-level research identifies the local market. Provider address tools determine what can actually be ordered at the property.
