If you’ve lived in rural Texas for more than a few years, you’ve had the conversation. Usually it starts with someone from out of town asking why your internet is so slow. You give them the look — the one that says you stopped being surprised about this a long time ago — and you try to explain something that doesn’t really make sense until you understand how broadband infrastructure gets built in America.

This isn’t a complaint column. It’s an explanation. Because understanding why rural Texas internet has historically been bad is the first step to understanding what’s actually changing — and why.

The Economics of Infrastructure

Broadband providers are private companies. They build infrastructure where it’s profitable to do so. A fiber run costs anywhere from $20,000 to $80,000 per mile to install, depending on terrain and permitting. Urban areas with dense housing can amortize that cost across hundreds or thousands of customers per mile. Rural areas with one house every quarter mile cannot.

That’s not a conspiracy. It’s arithmetic. AT&T, Spectrum, and every other major provider have made rational economic decisions to build where the math works and skip where it doesn’t. Medina County has about 40 people per square mile. Harris County (Houston) has about 2,800. The infrastructure investment per customer is dramatically different.

The result: rural Texas has been served by whatever technology was cheapest to deploy — DSL over copper telephone lines that date to the 1970s and 80s, or satellite systems that were designed for basic email access, not video calls and remote work.

How Federal Policy Made It Worse

For decades, federal universal service programs required telephone companies to provide basic telephone service everywhere. Broadband was treated differently. The assumption — which lingered well into the 2010s — was that broadband was a luxury, not a utility.

By the time policy caught up with reality, the big providers had already locked in their infrastructure positions. FCC Form 477 — the filing that determines official broadband availability — allowed providers to claim an entire census block as “served” if they could deliver broadband to even one location in that block. One house with fiber at the edge of a block meant the entire block was marked served on federal maps, even if 90% of the block had no viable broadband option.

Those maps influenced where federal funding went. If your area was already “served” on paper, it was deprioritized for funding. Rural Texas counties — including much of Medina, Atascosa, and Frio — spent years in a catch-22: technically served on federal maps, actually underserved on the ground.

What DSL Actually Delivers in 2026

Let’s be specific about what “served by AT&T” has meant for most of rural Medina County.

DSL internet runs over copper telephone wire. The technology works, but its performance degrades with distance — the farther you are from the telephone switching station, the slower your connection. In dense areas, most homes are close enough to a station to get reasonable speeds. In rural areas, you might be three to five miles from the nearest DSLAM. At that distance, 10 Mbps is a good day.

Those copper lines are also aging. They were installed decades ago and were not designed to carry broadband. Moisture intrusion, oxidized connections, damaged conduits — all of it degrades performance further. In parts of rural Medina County, customers with “broadband service” are getting 3–7 Mbps on a good day. That’s below the FCC’s own definition of broadband.

What’s Actually Changing

Two things have meaningfully shifted the landscape for rural Texas internet.

First, fixed wireless technology improved dramatically. The radio equipment used to deliver internet signals wirelessly from towers to homes has gotten faster, cheaper, and more reliable. What was 25 Mbps technology ten years ago is 400+ Mbps technology today. That improvement made it economically viable for local providers — not the national giants — to build coverage in rural areas that AT&T and Spectrum would never touch.

Second, federal funding priorities shifted. The RDOF and subsequent programs directed billions in subsidies toward rural broadband deployment. That funding, combined with improved technology, has accelerated buildout in underserved areas.

South Texas Internet has been serving Medina, Atascosa, and surrounding counties for years — long before federal broadband funding became a headline issue. We built our tower network because the need was real and the technology made it possible, not because a grant made it temporarily profitable.

Where Things Stand Today

Rural Texas internet is no longer uniformly terrible. It’s uneven — dramatically better in some areas, still stuck in the DSL era in others. Whether your address has a good option depends on your exact location, your proximity to a fixed wireless tower, and which providers have invested in your area.

The honest advice: don’t assume. Check what’s actually available at your address. The landscape has changed enough in the last three to five years that assumptions based on past experience may be outdated. Addresses that couldn’t get fixed wireless two years ago may be in our coverage area today.
