DSL (Digital Subscriber Line) delivers internet over existing copper telephone wires — the same physical lines used for landline phone service. It's slower than cable or fiber, but its broad availability makes it a critical option for millions of rural and suburban households that lack access to faster infrastructure. If cable or fiber isn't available at your address, DSL is usually the next-best wired option.

Five providers account for the majority of DSL coverage in the U.S. Most are actively upgrading their DSL footprints to fiber, but DSL remains available (and in many cases the only wired option) across millions of addresses.

When to choose DSL: If cable, fiber, or fixed wireless aren't available at your address, DSL is almost always better than satellite — lower latency, no weather disruption, no hard data caps. CenturyLink's price-for-life guarantee also eliminates the price-hike anxiety common with cable promotions.
FAQ
Frequently Asked Questions — DSL Internet 2026
What is DSL internet and how does it work?▼
DSL (Digital Subscriber Line) transmits data over existing telephone copper wire. Unlike dial-up, DSL uses frequencies above voice calls so you can use internet and phone simultaneously. The connection runs from a local telephone exchange to a DSL modem in your home. Speed depends heavily on how far you are from the provider's nearest node.
How fast is DSL internet?▼
Standard DSL speeds range from 1–100 Mbps download and 1–10 Mbps upload. VDSL2 (the newest version) can reach 100–140 Mbps close to the exchange. Speeds degrade with distance — if you're far from the provider's node, real-world speeds may be 20–50 Mbps even on a plan advertised at 100 Mbps.
Who are the best DSL internet providers?▼
Leading DSL providers in 2026 are CenturyLink/Quantum Fiber (16+ states, price-for-life guarantee), Frontier (25 states), EarthLink (nationwide reseller), Brightspeed (20 states, spun off from CenturyLink), and AT&T (21 states). CenturyLink's price-for-life guarantee makes it particularly attractive for budget-conscious households.
Is DSL internet fast enough for streaming?▼
Yes, for standard HD streaming. Netflix requires 5 Mbps for HD; most DSL plans offer 25–100 Mbps. 4K streaming needs 25 Mbps, achievable on faster DSL tiers. For households with multiple simultaneous streams or video calls, upgrade to 50–100 Mbps DSL or consider cable or fiber if available at your address.
How much does DSL internet cost per month?▼
DSL plans typically cost $35–$65/mo. CenturyLink DSL starts at $50/mo with a price-for-life guarantee. Frontier DSL starts around $40/mo. EarthLink DSL plans range from $50–$80/mo. Equipment rental adds $10–$15/mo, though most providers allow you to use your own compatible DSL modem.
Is DSL better than satellite internet?▼
In most cases, yes. DSL has lower latency (20–60 ms vs. 600+ ms for traditional satellite) and no severe weather disruptions. It's also less affected by data deprioritization under heavy network load. However, if your DSL speeds are below 25 Mbps, fixed wireless (T-Mobile, Verizon) or Starlink may offer better performance.
Is DSL internet available in rural areas?▼
Yes — DSL coverage extends wherever telephone landlines exist, which includes many rural areas not served by cable or fiber. It's often the best wired option for rural households. However, speeds drop sharply with distance from the provider's node, so rural customers may see much lower real-world speeds than the plan's advertised maximum.
What equipment do I need for DSL internet?▼
You need a DSL modem (and a separate Wi-Fi router, or a combo modem-router). Most ISPs rent a combo unit for $10–$15/mo. Compatible DSL modems cost $50–$100 to purchase outright. No new phone line installation is needed — DSL uses your existing telephone wiring. A DSL filter (microfilter) on phone jacks prevents audio interference.
What is the difference between DSL and cable internet?▼
DSL uses telephone copper wire; cable uses coaxial cable. Cable is significantly faster (100 Mbps–2 Gbps vs. 1–140 Mbps for DSL) and doesn't degrade with distance the way DSL does. DSL is available in more locations, particularly rural areas, and is often cheaper. If cable is available at your address, it's almost always the better choice.
Is DSL internet being phased out?▼
Gradually, yes. AT&T, Frontier, and CenturyLink are all actively replacing DSL infrastructure with fiber. However, in areas without fiber, DSL remains available and will continue serving millions of customers for years. The FCC's BEAD program is accelerating rural broadband expansion, which will eventually replace much of the remaining DSL footprint.
What is bonded DSL?▼
Bonded DSL combines two or more DSL lines to effectively double or triple available bandwidth. It's available from some providers in areas where a single DSL line can't deliver adequate speeds and can achieve 100+ Mbps in areas that would otherwise be limited to 25–50 Mbps. Ask your provider if bonded DSL is available at your address.
Can I keep my phone line if I switch to DSL internet?▼
Yes. DSL uses a frequency range above voice calls, so both coexist on the same copper line. You can have an active phone number and DSL internet on the same line simultaneously — just install DSL microfilters on any phone jacks you use. Some providers also offer dry-loop DSL that doesn't require active voice service if you've ditched your landline.
