Roles count plans reaching at least 5% of San Marcos. Faster only in small pockets: Frontier Fiber 7 Gig up to 7,000 Mbps (~4% of the city).

Spectrum is the best overall, with cable speeds up to 1,000 Mbps reaching about 76% of the city. AT&T is the fastest where available, with fiber speeds up to 5,000/5,000 Mbps reaching about 8% of the city, and if it reaches your address, it is the faster choice. Where Spectrum does not reach, Brightspeed is the broadest backup, mostly DSL across about 49% of the city, with its fastest common DSL tier reaching up to 60 Mbps across about 6%.

Local availability shifts quickly: in Blanco Gardens, Spectrum reaches about 29% of the ZIP, while Astound Broadband reaches about 26%, and Astound’s fiber reaches about 23%. ZIP 78667 is the standout, with Astound Broadband fiber reaching about 94%, while Spectrum reaches only about 1% there. Rio Vista and Springtown can look different from either ZIP, and older apartments or homes may still be limited by DSL or copper infrastructure. For students at Texas State University and Austin Community College San Marcos Campus, reliable service matters for Zoom, streaming, and gaming, so check the exact address before choosing, since coverage can change street by street.

Spectrum’s cable Internet Gig plan has a Speed Score of 80/100, above the city average of 67, making it a solid, reliable choice for most households. Availability is address dependent, with this plan reaching about 76% of San Marcos, so confirm your address qualifies before signing up.

About Spectrum

Spectrum’s cable service offers up to 1,000 Mbps download and 35 Mbps upload, which is excellent for households with multiple streamers, gamers, remote workers, and smart devices. The fastest plan is available to about 76% of San Marcos, but availability is address-dependent, so check your address first; the 500 Mbps plan is also a strong choice, while the 100 Mbps option may be adequate for lighter use but offers less room for a busy modern household.

THE TAKEAWAY

Our recommendation for San Marcos

At $90/mo for 12 months, AT&T Internet 5 GIG offers up to 5,000 Mbps both ways, a $150 reward card, and a 95/100 Speed Score that is above the city average of 67, making it a top-tier fiber option. Availability is address-dependent, and this plan reaches about 8% of San Marcos, so check your address to confirm that the high-performing fiber service is available rather than AT&T Internet Air fixed wireless.

Speeds and reach below are what the provider files with the FCC for each technology tier, by census block. The plans it actually sells here, with their own speeds and prices, are under Pricing & Plans; the two can differ.

About AT&T

AT&T offers strong value where its fiber is available, with $35/mo for up to 300 Mbps both ways, $50/mo for up to 1,000 Mbps both ways, and $90/mo for up to 5,000 Mbps both ways. These are excellent options, but fiber availability is address-dependent and the 5,000 Mbps plan reaches only about 8% of San Marcos, while the fixed-wireless Internet Air plan reaches about 21% and offers up to 300 Mbps download and 30 Mbps upload. Check for fiber first, since Internet Air is a reasonable alternative but may be less suitable for heavy uploads or demanding households.

THE TAKEAWAY

Our recommendation for San Marcos

Brightspeed’s plan offers up to 100 Mbps download and 50 Mbps upload, suitable for basic browsing, streaming, and smaller households, but its 18/100 Speed Score is well below San Marcos’s city average of 67. This DSL service has limited performance compared with alternatives, so consider checking other providers first for demanding gaming, video calls, or multiple simultaneous users. The plan is available to about 0% of San Marcos, so confirm the technology and speeds offered at your address.

Speeds and reach below are what the provider files with the FCC for each technology tier, by census block. The plans it actually sells here, with their own speeds and prices, are under Pricing & Plans; the two can differ.

About Brightspeed

Up to 100 Mbps over DSL can handle basic browsing, video calls, and streaming for a small household, but it may feel limiting with many connected devices or heavier use. This is a below-average option with a Speed Score of 18/100, so check for faster internet first, since Brightspeed’s availability and speed depend on your address.

GVTC’s fiber plan is an excellent, top-tier option with a Speed Score of 80/100, above San Marcos’s average top speed score of 67, and is available to about 6% of the city. Your address may instead be served by GVTC’s copper plan, which offers up to 10 Mbps download and 1 Mbps upload with a Speed Score of 1/100, so consider checking other providers first if fiber is not available.

About GVTC

GVTC’s fastest option is fiber with up to 1000 Mbps download and 250 Mbps upload, an excellent choice for streaming, video calls, gaming, and multiple connected devices.

THE TAKEAWAY

Our recommendation for San Marcos

Households that need fast, low-latency service for streaming, remote work, gaming, or many connected devices should consider Guadalupe Valley Electric Coop’s fiber plan. It offers up to 1000 Mbps download and 1000 Mbps upload, has a Speed Score of 80, and reaches about 5% of San Marcos, making it an excellent, top-tier option that is above the city’s average top speed score of 67. Because availability depends on your address, verify that fiber is offered there, since the provider’s Lbr Fixed Wireless plan is limited to up to 100 Mbps download and 20 Mbps upload with a Speed Score of 18.

About Guadalupe Valley Electric Coop

Homes with heavy streaming, gaming, or remote-work needs should consider Guadalupe Valley Electric Coop for its excellent fiber option, with up to 1000 Mbps both ways.

THE TAKEAWAY

Our recommendation for San Marcos

Where available, its fiber plan is an excellent choice, offering up to 1000 Mbps download and 200 Mbps upload with a Speed Score of 80/100, above the city’s average top speed score of 67. Availability is highly address-dependent, so check your exact address to confirm this top-tier option reaches your home.

Verizon’s 5G fixed wireless service offers up to 300 Mbps download and 75 Mbps upload, which can support streaming, video calls, and everyday browsing, though fixed wireless may be less consistent than wired connections. Its 5G Home plan has a Speed Score of 66/100, about the same as San Marcos’s city average of 67, making it an adequate option rather than a standout. Availability depends on your address, with this plan reaching about 74% of the city, so check your location before signing up and compare available technologies if you need the most consistent performance.

Speeds and reach below are what the provider files with the FCC for each technology tier, by census block. The plans it actually sells here, with their own speeds and prices, are under Pricing & Plans; the two can differ.

About Verizon

Verizon’s 5G fixed wireless service offers up to 300 Mbps download and 75 Mbps upload, which is adequate for streaming, video calls, and everyday browsing, though its below-average 66/100 speed score means it may feel limited for heavier households. It is available to about 74% of San Marcos, but performance depends on your address, so check whether faster fiber or cable options are available before choosing it, especially if several people regularly work, study, or game online.

THE TAKEAWAY

Our recommendation for San Marcos

At $94.99/mo for the first 12 months, then $119.99/mo, HughesNet Fusion buys up to 100 Mbps download and 5 Mbps upload, but its 18/100 Speed Score is below San Marcos’s city average of 67. Because all listed plans use satellite technology, performance is more limited and latency is typically higher than with fiber or cable, so consider checking other providers first and confirm availability at your specific address. Fusion is available to 100.0% of San Marcos, while the cheaper Select and Lite plans offer lower speeds and scores.

Speeds and reach below are what the provider files with the FCC for each technology tier, by census block. The plans it actually sells here, with their own speeds and prices, are under Pricing & Plans; the two can differ.

About HughesNet

At $39.99 to $94.99 per month for the first 12 months, HughesNet offers up to 25 to 100 Mbps download speeds, but those satellite plans provide below-average value for today’s streaming, gaming, and work needs, especially after the promotional rates end. All three plans are available to 100% of San Marcos, yet you should check your address for faster fiber, cable, or other options first because satellite’s higher latency and limited performance may not be sufficient for modern internet use.

THE TAKEAWAY

Our recommendation for San Marcos

Viasat is a limited-performance option compared with other technologies, with Viasat Essentials offering up to 55 Mbps download and 4 Mbps upload for a Speed Score of 17/100, below the San Marcos city average of 67. Essentials is available to 100.0% of the city, but satellite’s higher latency and lower scores make it worth checking other providers available at your address first.

Speeds and reach below are what the provider files with the FCC for each technology tier, by census block. The plans it actually sells here, with their own speeds and prices, are under Pricing & Plans; the two can differ.

About Viasat Inc

Viasat Inc is a widely available fallback, but you should check for faster internet first because its satellite plans are below average, with Viasat Essentials offering up to 55 Mbps download and 4 Mbps upload for $69.99 per month, and Viasat Unleashed offering up to 34 Mbps download and 4 Mbps upload for $99.99 per month. Both plans reach 100% of San Marcos, but satellite can have high latency and may be limiting for modern needs such as heavy streaming, video calls, and gaming.

What internet is available in Blanco Gardens?

How We Analyze Internet in San Marcos

FCC Broadband Data

We use the FCC National Broadband Map, updated twice a year with provider-reported coverage at the census block level.

Speed Score

A state-wide percentile of each plan’s maximum advertised download speed against every option filed with the FCC in the state, all technologies on one scale. It is not a measured speed test.

Coverage Calculation

Provider coverage shows what percentage of census blocks in San Marcos report service availability from each provider.

Data Coverage for San Marcos

ZIP Codes Analyzed:
7866678667
Census Tracts: 28 tracts
Census Blocks: 1,663 blocks analyzed

How We Calculate Speed Score

The Speed Score is a state-wide percentile from 0 to 100. It answers one question: of every internet option filed with the FCC in this state, across every technology, what share is slower than this plan’s maximum advertised download speed?

What goes in:

  • The plan’s maximum advertised download speed, as the provider files it with the FCC and lists it for sale.
  • Every other serviceable option in the state from the FCC Broadband Data Collection, counted by the census blocks it reaches.

Speed Score = share of the state’s filed options with a lower advertised download speed

A score of 85 means this plan’s advertised speed beats 85% of the options filed in the state. Fiber, cable, DSL, fixed wireless and satellite are all on the same scale, so a 1,000 Mbps plan scores the same whoever sells it.

What it is not: a measured speed test. It does not include latency, upload speed, reliability or congestion. Real throughput at an address varies with wiring, equipment and time of day.

How providers are ordered on this page: each provider’s tier scores are averaged across the census blocks it serves, then multiplied by the share of the city it reaches. Wired providers rank ahead of wireless-only ones, and satellite last, because their filings describe a signal footprint rather than a plant. The same rule sets the title and the 30-second verdict.

Data source: FCC National Broadband Map (Broadband Data Collection), republished roughly twice a year; provider plan lists checked monthly.

How We Calculate Capabilities

Estimated Capabilities predict how well each internet plan supports common household activities based on speed requirements and connection type.

Rating Scale:

  • Excellent – Optimal performance, handles peak usage easily
  • Good – Reliable performance with minimal issues
  • Fair – Functional but may experience slowdowns during heavy use
  • Poor – Not recommended; expect frequent buffering or lag

How We Rate Each Category:

Streaming

Based on download speed. 4K streaming requires 25+ Mbps per stream; HD requires 5+ Mbps. We account for multiple simultaneous streams.

Multi-device

Evaluates total bandwidth capacity divided by typical household device count (phones, tablets, smart TVs, computers). Fiber and cable handle many devices better than DSL or satellite.

Gaming

Considers both upload speed (for sending game data) and latency (ping time). Fiber and cable excel here; satellite connections struggle due to inherent signal delay.

Whole Home

Assesses whether the connection can reliably serve an entire household during peak evening hours. Factors in technology type (shared vs. dedicated bandwidth) and total speed capacity.

Note: Actual performance depends on your specific location, network congestion, and equipment quality.
