DSL speed test: check your speed and what's normal
DSL speed depends on how far you live from the phone company's equipment. Here's how to test your line, what's normal, and when to switch.
Test on a computer wired to the DSL modem, three times, and compare with the speed you were sold, not the "up to" number. Most DSL lines run between 1 and 100 Mbps, and the farther you are from the phone company's equipment, the lower that number. Use our speed test. If wired results are close to your plan, the line is doing all it can.
DSL speeds by provider
From provider plan listings and published speed-test averages (BroadbandNow, HighSpeedInternet.com, CompareInternet), 2026. Averages mix DSL and fiber where noted.
If your provider also sells fiber at your address, a DSL speed test result usually isn't worth fixing; ask about switching. Many offer fiber at the same or lower price.
What's a normal DSL speed?
Older DSL lines usually top out around 10 to 25 Mbps. Newer VDSL lines from Frontier, Brightspeed and Kinetic can reach 50 to 100 Mbps if you live close to the equipment. Uploads are much lower, often 1 to 10 Mbps. The Broadband Facts label for your plan lists the typical speed the provider expects you to get.
How to run an accurate DSL test
- Plug a laptop into the DSL modem with an Ethernet cable. Wi-Fi results tell you about your Wi-Fi, not your line.
- Pause other devices and downloads.
- Test three times, at different times of day.
- Open the modem's status page and note the sync rate, the most your line can carry. If your test is close to the sync rate, you've hit the line's limit.
Why distance matters
DSL runs over copper phone lines, and the signal weakens with distance. Past roughly two to three miles from the phone company's equipment, speeds fall off sharply. A new router won't change that; only a different connection will.
Fixes that help
- Plug the modem into the first phone jack in the home, not an extension.
- Put a DSL filter on every phone and fax on the line.
- Swap old or long phone cords for a short new one.
- Restart the modem, then test again wired.
- Ask the provider for a line test. Noise on the line is something only they can fix.
DSL is being phased out
Many phone companies have stopped selling new DSL and are retiring copper lines. See the copper phase-out for what that means for your line.
When to switch
If your wired DSL tests under 25 Mbps, check what else reaches your address. Fiber is the biggest upgrade where it's available. Otherwise 5G home internet from Visible, T-Mobile or Verizon usually beats DSL by a wide margin, often for less: Visible Home Internet is $30/mo with a Visible line, T-Mobile 5G Home is $50/mo ($35 with a phone line), and Mint Home MINTernet is $40/mo paid a year up front. In rural areas, see the best rural internet. See what's available at your address.
Questions
Is 10 Mbps DSL good?
It's enough for email, browsing and one HD stream. It struggles with several streams, video calls and large downloads at the same time.
What is the fastest DSL speed?
VDSL can reach about 100 Mbps for homes very close to the provider's equipment. Most DSL lines are much slower.
Why is my DSL slower than advertised?
Usually distance from the provider's equipment, line noise or old wiring. Test wired and compare with your modem's sync rate.
Is DSL being discontinued?
Many providers have stopped selling new DSL and are retiring copper lines in some areas. Existing customers are usually offered fiber or wireless where it's available.
