Tools

Free Wi-Fi Test Kit

Compare speed, latency, placement, mesh, and band clues before calling your ISP, buying mesh, replacing your router, or changing your internet plan.

Built for controlled retests

Change one thing, record the same number again, and keep the result tied to the diagnosis instead of guessing from a single speed test.

Enter the numbers you already have, compare the pattern, and send the strongest signal into the full diagnosis.

Start Diagnosis

Speed Pattern Checker

Compare plan, near-router, problem-room, and wired results.

Worth testing

Coverage or placement is the strongest signal

The problem-room speed drops sharply from the near-router result. That usually means the plan is not the first thing to change.

Signal

95 Mbps in the problem room vs 420 Mbps near the router

Near router vs plan

84%

Shows whether speed is healthy before room layout gets involved.

Problem room vs near router

23%

Shows whether Wi-Fi drops sharply by location.

Next step

Move the router higher and more central if possible, then retest the exact same problem-room spot.

What not to do yet

Do not upgrade the internet plan until the location drop is addressed.

Each guide explains one check in plain English and links back to the full diagnosis when the pattern fits.

Speed Pattern Checker

Compare plan speed, near-router speed, problem-room speed, and wired speed.

Best for

Figuring out whether slow Wi-Fi is really coverage, the ISP/modem side, or a normal Wi-Fi speed limit.

Band Choice Helper

Decide whether 2.4 GHz, 5 GHz, or 6 GHz makes sense for a device.

Best for

Smart devices, older streaming sticks, combined Wi-Fi names, and rooms where range matters more than top speed.

Router Placement Check

See whether router location is creating a false hardware problem.

Best for

Routers hidden in cabinets, corners, TV stands, closets, low shelves, or one side of the home.

Loaded Latency Check

Explain lag and frozen calls when download speed looks normal.

Best for

Gaming lag, Zoom or Teams freezes, upload-heavy cloud backup, and homes where speed tests look fine.

Helpful to have, but not required

You can start with just your symptom.

These details make the result more accurate if you have them. If you do not know one, skip it and keep going.

  • Internet plan speed, if known
  • One speed test near the router
  • One speed test in the problem room
  • Whether the issue affects one device or many
  • Idle and loaded latency, if gaming or video calls are the issue
  • Optional wired speed test, if you can plug in directly
