Broadband service in 78734 spans Lakeway, Hudson Bend and surrounding Lake Travis communities. The ZIP has established cable service, AT&T fiber and a growing GFiber network, while fixed wireless adds another layer of competition. Fiber construction is also changing the local provider map block by block.

78734 is a particularly important ZIP for tracking fiber expansion because Lakeway is receiving a new GFiber network while established Spectrum and AT&T networks remain part of the market. Fixed wireless providers extend the available choices beyond the wired network footprint.
The City of Lakeway maintains a dedicated GFiber construction page. It identifies an initial construction area along Hurst Creek Road toward Lohmans Crossing and RR 620 and provides additional project maps for Lakeway Drive, Vanguard, Atlantic, Highlander, Lakeway Boulevard and the Duck Lake area. The city also says it cannot determine the exact neighborhood service date for individual addresses.
Current broadband datasets identify Spectrum as the dominant cable network in the Lakeway market, while AT&T Fiber is reported across a substantial portion of the area. Spectrum also has a smaller fiber footprint. This means the relevant comparison at many addresses is not simply wired versus wireless, but which wired technology reaches the property.
ZIP-level data reports T-Mobile Home Internet and Verizon fixed wireless across much of the 78734 market, with smaller fixed-wireless networks also appearing in the data. These services can matter at properties where a particular fiber build has not reached, but wireless eligibility remains address and capacity dependent.
This table separates direct provider or municipal evidence from ZIP-level broadband records. The availability figures are useful for understanding the local market but are not a substitute for a live address check.
| Provider | Technology | 78734 evidence | Advertised maximum | What to verify |
|---|---|---|---|---|
|
AT&T Fiber
Local fiber service
|
Fiber | AT&T's Lakeway service page confirms home internet service in Lakeway and advertises fiber availability in the market. Current ZIP-level data also reports AT&T Fiber in 78734. | Up to 5 Gbps where available | Exact address, fiber tier and installation requirements |
|
GFiber
Active Lakeway build
|
Fiber | The City of Lakeway documents active GFiber construction, including Hurst Creek Road toward Lohmans Crossing and RR 620, plus other mapped construction areas. | Multi-gig plans where service is released | Whether construction is complete and the address is orderable |
|
Spectrum
Major local network
|
Cable; limited fiber footprint | Current ZIP-level datasets report approximately 99.8% cable availability in 78734 and a much smaller fiber footprint. Spectrum also maintains a Lakeway service presence. | Up to 1 Gbps in the current local data | Residential technology, plan tier and upload speed |
|
T-Mobile 5G Home Internet
Broad wireless presence
|
5G fixed wireless | Current ZIP-level datasets report T-Mobile Home Internet across most of the 78734 market. T-Mobile's own eligibility system requires an exact address. | Plan-dependent; wireless speeds vary | Address eligibility, signal and network capacity |
|
Verizon 5G Home Internet
ZIP-level wireless evidence
|
Fixed wireless | Current ZIP-level broadband datasets report Verizon fixed wireless availability across a large portion of the 78734 market. | Up to 300 Mbps in the cited ZIP-level dataset | Exact address and current 5G Home eligibility |
|
Astound Broadband
Small fiber footprint
|
Fiber | Current ZIP-level broadband data reports a small Astound fiber footprint in 78734. The reported coverage is much smaller than Spectrum or AT&T and should be treated as property-specific. | Up to 1.5 Gbps in the cited data | Whether the individual property falls inside the footprint |
|
Nextlink / Hill Country Networks
Limited fixed wireless
|
Fixed wireless | Current Lakeway broadband records identify smaller fixed-wireless footprints from Nextlink and Hill Country Networks. Their coverage is substantially more limited than the major networks. | Provider and location dependent | Line of sight, service footprint and address eligibility |
78734 has a more complicated provider map than its ZIP boundary suggests. Lakeway, Hudson Bend and other communities inside the ZIP have different infrastructure histories, and GFiber construction is being completed in phases rather than appearing everywhere simultaneously.
AT&T has a documented home-internet presence in Lakeway, and its current local page says many Lakeway homes may qualify for AT&T Fiber. The provider advertises speeds up to 5 Gbps where available. Current ZIP-level broadband data separately reports AT&T Fiber in a substantial portion of 78734.
GFiber is the most significant infrastructure change documented for 78734. The City of Lakeway maintains a dedicated construction page showing work in multiple parts of the city. The first phase described by the city ran along Hurst Creek Road toward Lohmans Crossing and RR 620, with additional mapped work around Lakeway Drive, Vanguard, Atlantic, Highlander, Lakeway Boulevard and Duck Lake.
Spectrum is the established cable network against which the newer fiber deployments in 78734 should be compared. Current ZIP-level broadband records report roughly 99.8% cable availability for Spectrum in the Lakeway market, while also showing a much smaller Spectrum fiber footprint.
T-Mobile Home Internet is an important alternative in 78734 because its fixed-wireless network does not require a cable or fiber line to reach the home. Current ZIP-level broadband data reports T-Mobile Home Internet across most of the Lakeway market.
Verizon is another fixed-wireless alternative reported in current 78734 broadband data. The cited ZIP-level dataset reports Verizon fixed wireless across a large portion of the Lakeway market. Verizon's own home-internet guidance says service options depend on the exact address and directs customers to its availability checker.
Astound appears in current ZIP-level broadband records as a small fiber provider in 78734. The reported footprint is approximately 1% of the Lakeway market in the cited data, making Astound a property-specific possibility rather than a general ZIP-wide option.
The local technology mix makes upload performance particularly relevant. A fiber connection from AT&T or GFiber can have materially different upload characteristics from a cable connection, while fixed wireless performance can change with radio conditions and network capacity.
A reasonable range for ordinary browsing, video calls, streaming and smaller households when the connection is stable.
Useful for households with several simultaneous users, multiple streaming devices and heavier downloads.
More relevant for larger households, substantial downloads, home offices and many simultaneously active devices.
Only relevant where the property has a supporting fiber network and the provider actually offers the tier. Network hardware can become the limiting factor.
The local broadband market is shaped by both established infrastructure and new construction. That distinction matters because a provider can appear in the ZIP while a particular neighborhood is still waiting for construction or activation.
AT&T Fiber is already represented in 78734, while GFiber is expanding through active Lakeway construction. Current data also reports a small Astound fiber footprint and a smaller Spectrum fiber footprint.
Spectrum is the principal cable network identified in current ZIP-level data. Cable remains an important baseline because it is already established while portions of the Lakeway fiber market are being expanded.
T-Mobile and Verizon provide fixed-wireless alternatives, while Nextlink, Hill Country Networks and AT&T Internet Air also appear in local broadband datasets at smaller or technology-specific footprints.
Satellite remains geographically relevant around the Lake Travis area, particularly where a property lacks a suitable wired or terrestrial fixed-wireless option. It has materially different latency and service characteristics from fiber and cable.
78734 is not simply an Austin suburban ZIP with one dominant network. It encompasses Lakeway and Hudson Bend and includes residential areas with different construction histories, terrain and proximity to Lake Travis. The current GFiber buildout adds another layer because fiber availability is progressing through specific construction areas rather than appearing everywhere at once.
The City of Lakeway maintains an official GFiber project page and says the first construction phase took place along Hurst Creek Road toward Lohmans Crossing and RR 620. The city also publishes maps showing additional areas of completed or ongoing construction. This provides stronger local evidence than simply listing GFiber as an Austin provider.
Current Lakeway broadband data reports Spectrum cable availability across approximately 99.8% of the local market, while AT&T Fiber is reported across a substantial portion and Spectrum has a much smaller fiber footprint. The practical issue for a 78734 household is therefore which network reaches the specific property, not whether cable or fiber exists somewhere in the ZIP.
The City of Lakeway explicitly says it cannot provide exact individual-neighborhood construction timelines or tell residents when a particular address will become serviceable. That distinction matters in 78734 because a construction map and an orderable service address are two different stages of deployment.
ZIP 78734 covers both Lakeway and Hudson Bend, along with other surrounding areas. Current geographic sources identify the ZIP across multiple communities rather than a single municipal boundary. Provider networks follow streets, utility infrastructure and serviceable locations instead of the ZIP boundary.
Current Lakeway broadband records identify T-Mobile Home Internet, Verizon 5G Home, AT&T Internet Air and smaller fixed-wireless networks. This matters for properties waiting for fiber construction or outside a particular wired footprint, although wireless eligibility still depends on local capacity and signal conditions.
These findings focus on infrastructure that can actually distinguish 78734 from a generic Austin provider page.
| Finding | Evidence | What it means for a 78734 address |
|---|---|---|
| GFiber Lakeway buildout | City of Lakeway documents construction around Hurst Creek Road, Lohmans Crossing and RR 620 and publishes additional project maps | GFiber should be checked independently even when an older provider list does not show it. |
| AT&T Fiber | AT&T's Lakeway service page confirms local home internet service and says many Lakeway homes may qualify for fiber | AT&T should be checked as a fiber option rather than treated only as a legacy DSL provider. |
| Spectrum cable | Current Lakeway broadband data reports approximately 99.8% cable availability | Spectrum is an established wired baseline while newer fiber networks are expanding. |
| Spectrum fiber | Current ZIP-level data reports a much smaller Spectrum fiber footprint than its cable footprint | Do not assume a Spectrum address is fiber simply because Spectrum is available. |
| T-Mobile Home Internet | Current ZIP-level data reports broad fixed-wireless coverage; T-Mobile requires an address eligibility check | Wireless can be an alternative where a wired provider is unavailable or not yet expanded. |
| Verizon 5G Home | Current ZIP-level data reports Verizon fixed wireless across a substantial portion of the market | Worth checking separately from T-Mobile because the two networks have different infrastructure and eligibility. |
| Small fiber providers | Astound is reported at approximately a 1% local footprint in the cited data | Smaller providers can matter at individual properties even when they are not meaningful ZIP-wide competitors. |
| Small fixed-wireless networks | Nextlink and Hill Country Networks appear in current Lakeway broadband records at smaller footprints | Properties outside major wired footprints may have additional local wireless options. |
The locations below are useful for understanding why broadband infrastructure can differ within the ZIP. They are geographic reference points, not guarantees of provider availability.
Neighboring ZIP codes can have materially different provider footprints. Use them as separate research areas rather than assuming a nearby ZIP has the same fiber, cable or fixed-wireless infrastructure as 78734.
The correct sequence for this ZIP is to identify the existing network, check whether new fiber construction has reached the property, and then use the provider's address-level system.
The Lakeway GFiber construction maps are useful evidence that network construction is occurring in specific parts of the city. They are not equivalent to an address-level service checker. The city itself says it cannot provide exact individual-neighborhood service dates and directs residents to GFiber for current status.
The current local market makes the physical network reaching the property one of the first questions to answer. The same provider name can represent different technologies, and the technology can affect upload performance and network characteristics.
A construction map can show that GFiber is being deployed nearby, but it does not establish that a particular home can order service. Check the exact address after construction progresses.
AT&T Fiber and GFiber can offer fiber-based service, while Spectrum remains heavily represented through cable. Similar download tiers can therefore have different upload characteristics.
78734 contains Lakeway, Hudson Bend and surrounding communities. A provider or fiber project documented in one part of the market should not automatically be treated as available at an address in another part of the ZIP or across a ZIP boundary.
ZIP-level research identifies the local market. Provider address tools determine which network and plan can actually be ordered at the property.
