Speed Tests
Speed Test by Provider
Every network technology behaves differently - cable, fiber, 5G fixed wireless and satellite each have their own quirks. Pick your provider for a speed test plus what speeds and latency you should realistically expect.
Comcast Xfinity
Cable & FiberTest your Comcast Xfinity internet speed to see if you are getting the bandwidth you pay for. Xfinity offers cable and fiber-gig plans, and real-world...

Fiber & DSLRun an AT&T speed test to check whether your fiber or DSL connection hits its rated speeds. AT&T Fiber generally delivers low latency and symmetric up...
Run the AT&T speed test →Verizon Fios
FiberTest your Verizon Fios connection speed. Fios is a pure fiber-optic service, so a healthy connection should deliver low ping, low jitter, and near-sym...

CableRun a Spectrum speed test to verify your Charter Spectrum connection. Spectrum cable plans are marketed as "starting at" speeds with no contracts, but...
Run the Spectrum speed test →T-Mobile Home Internet
5G Fixed WirelessTest your T-Mobile 5G Home Internet speed. T-Mobile delivers broadband over the cellular network, so your speed depends on signal strength at the gate...

Run the Cox speed test →Why test per provider?
A speed test tells you what your connection delivers right now, but whether that number is good depends on what your provider sells you and the technology behind it. Cable upload is a fraction of download; fiber should be near-symmetric; 5G home internet swings with tower congestion; satellite depends on sky clearance.
Each provider page above embeds the full SpeedPulse test - download, upload, ping, jitter and a bufferbloat grade - plus the expected speed ranges and common issues for that provider, so you can judge your result instead of guessing.
