If you’re trying to get fast, reliable internet in Medina County, Texas, the honest answer is that your options depend heavily on your exact address. The county seat of Hondo has more choices than a ranch address on FM 462. A neighborhood off US-90 near Castroville has different infrastructure than a rural route near D’Hanis. This guide breaks down what’s actually available throughout Medina County — not what providers claim on their coverage maps, but what residents are actually dealing with.

The Infrastructure Reality in Medina County

Medina County covers roughly 1,300 square miles with a population of about 52,000. Most of that population is concentrated in Hondo and a handful of smaller communities — Castroville, Natalia, Devine, Lytle, and D’Hanis. The rest is ranchland, farmland, and rural residential scattered across county roads and farm-to-market routes.

That geography explains everything about internet options here. Cable and fiber providers build infrastructure where the return on investment makes sense. Dense urban areas get fiber. Rural counties get whatever’s left.

AT&T in Medina County

AT&T has the most infrastructure in Medina County, but that infrastructure varies dramatically by location. Parts of Hondo and Castroville have seen AT&T fiber expansion in recent years. If you’re lucky enough to be on one of those streets, AT&T fiber is a legitimate option — competitive speeds, reasonable reliability.

But outside those pockets, AT&T’s presence in Medina County means aging DSL over copper telephone lines. Those lines were not built for broadband. They degrade with distance from the switching station, they’re affected by weather and moisture, and they commonly deliver 10–25 Mbps in areas that AT&T’s own coverage maps show as “served.” If AT&T DSL is your only wired option, that’s not a broadband solution by any modern standard — the FCC defines broadband as 25 Mbps down / 3 Mbps up, and many DSL connections in this county barely meet that threshold.

Spectrum in Medina County

Spectrum does not meaningfully serve rural Medina County. Their cable infrastructure exists in some communities but stops at city limits in most areas. If you’re outside an incorporated area or in an unserved rural pocket, Spectrum is simply not available.

Satellite Internet: Starlink and HughesNet

Starlink has become the default fallback for rural Medina County residents who can’t get cable or fiber. It works — up to a point. Speeds of 100–150 Mbps are achievable under good conditions, and it reaches addresses that no other provider touches.

The downsides are real: $120/month plus a $599 equipment purchase upfront, weather sensitivity, latency that affects real-time applications, and no local support when something goes wrong. For addresses with zero other options, Starlink makes sense. For addresses where fixed wireless reaches, it’s hard to justify the cost.

HughesNet is still available in the county but rarely recommended in 2026. Data caps, slower speeds, and high latency put it behind Starlink for most use cases. The one scenario where HughesNet makes sense is a very light user who primarily needs email and basic browsing — but even then, the cost-to-performance ratio isn’t compelling.

Fixed Wireless: South Texas Internet

South Texas Internet serves Medina County with fixed wireless broadband from our local tower network. Our Velocity 400 plan delivers 400 Mbps download and 25 Mbps upload for $65/month — no equipment purchase, no contract, no data caps.

Fixed wireless reaches addresses throughout Hondo, Castroville, Natalia, Devine, D’Hanis, Quihi, Rio Medina, and dozens of rural routes and unincorporated communities across the county. Coverage is determined by line of sight to our nearest tower — if your address has a clear path to one of our towers, you can get connected.

We’ve been operating in Medina County for years. Our operations are based in Hondo. When you call (830) 429-4149, you’re talking to someone who works in this county, not a national call center.

How to Figure Out What’s Available at Your Address

Coverage maps from any provider — including ours — are approximations. The honest way to know what’s available at your specific address is to call each provider directly and ask them to confirm.

For STI, that confirmation takes a few minutes. We check your address against our tower coverage, give you a straight yes or no, and can usually schedule installation within one business day if you’re in our footprint.

For AT&T, ask specifically whether fiber or DSL is available — not just “internet.” The difference matters significantly.

For Starlink, you can check availability online at starlink.com with your address.

The Bottom Line for Medina County Residents

If you’re in Hondo or Castroville near the historic district: AT&T fiber may be available — check before defaulting to anything else. If it’s there, it’s a solid option.

If you’re in most of the rest of Medina County: your realistic choices are STI fixed wireless or Starlink. STI costs less, delivers faster speeds, and comes with local support. Starlink reaches addresses that STI can’t — extremely remote ranchland beyond our current tower footprint.

If you’re not sure what’s at your address, call us at (830) 429-4149. We’ll tell you what we know, and if we can’t serve you, we’ll tell you that too.
