Download fast, upload limited

5G Home Internet

100–300 Mbps
T-Mobile/Verizon — no contract needed

Tips for an Accurate US Speed Test

  • Run the test outside peak hours — US networks are heavily congested between 7–11 PM.
  • Connect via Ethernet to measure your plan speed without WiFi overhead.
  • Close streaming apps and background cloud syncs (iCloud, OneDrive, Dropbox).
  • If your ISP provides a speed guarantee, run the test 3 times and average the results.
  • Compare your result to the FCC broadband definition: 100 Mbps down / 20 Mbps up (2024 updated standard).

Xfinity (Comcast) Speed Test

Test your Comcast Xfinity cable or fiber internet connection.

Xfinity is the largest US internet provider, serving over 32 million subscribers on DOCSIS 3.1 cable and expanding Xfinity Gigabit Pro fiber. If your measured speed is significantly below your plan, try restarting the modem by unplugging it for 30 seconds. Xfinity cable connections can slow during neighborhood peak hours — fiber plans avoid this congestion entirely.

  • Xfinity cable plans: 75–1200 Mbps download, 10–35 Mbps upload.
  • Xfinity Gigabit Pro (fiber): 3000 Mbps symmetric.
  • Typical ping: 10–20 ms on East Coast servers.

Verizon Fios Speed Test

Test your Verizon Fios fiber internet — 100% fiber, fully symmetric.

Verizon Fios is a pure fiber-to-the-home network available in the Northeast US. Unlike cable providers, Fios delivers identical upload and download speeds — critical for video creators, remote workers, and gamers who stream. If Fios speeds are below expectations, check that the Optical Network Terminal (ONT) box has a solid green light on the PON indicator.

  • Fios plans: 300, 500, 1000 Mbps fully symmetric.
  • Typical upload: matching download — unique among major ISPs.
  • Typical ping: 5–15 ms — best-in-class for gaming.

AT&T Fiber Speed Test

Test your AT&T Internet Air or AT&T Fiber connection.

AT&T Fiber covers over 25 million locations across the US with FTTH service up to 5 Gbps. AT&T Internet Air is their fixed 5G home internet product. For fiber subscribers, if speeds drop significantly during evening hours, it may indicate a backhaul issue — contact AT&T support and reference your ONT MAC address for faster resolution.

  • AT&T Fiber: 300 Mbps–5 Gbps download.
  • Upload: 300 Mbps–5 Gbps (symmetric on fiber plans).
  • Typical ping: 8–18 ms.

T-Mobile Home Internet Speed Test

Test your T-Mobile 5G or 4G LTE home gateway.

T-Mobile Home Internet uses 5G and 4G LTE towers to deliver broadband without a cable installation. Median speeds are around 100–200 Mbps but vary widely by tower load. Place your gateway near a window facing the tower direction for best results. The T-Mobile app shows signal quality and tower direction.

  • Typical 5G download: 100–300 Mbps (varies by location).
  • Upload speeds: 15–50 Mbps — limited vs fiber/cable.
  • Typical ping: 30–60 ms — higher latency than wired.
