Lag tools

Find where your lag comes from, then fix it. Each tool works on its own; the Lag Check tells you which ones matter for you.

In your home

Device · Wi-Fi · Router

Weak or busy Wi-Fi, devices that scan on a timer, and downloads nobody noticed. Your provider can't fix these; you can.

  • Find

    Lag spike finder

    Records your ping ten times a second and names the pattern: a Mac's AirDrop radio, Wi-Fi scans, Starlink's cycle or other traffic.

    Find my spikes
  • Find

    Wi-Fi room check

    Walk your phone or laptop from room to room, test each one, and see where Wi-Fi adds lag and what to change there.

    Tame background downloads

    Where the limits live for Windows Update, Steam, consoles, OneDrive and backups, and the Mac setting behind spikes every second.

    Wi-Fi fixes

On your line

Modem · Line

When the line is busy, a queue builds up and every game packet and call waits behind it. Smart Queue on the router fixes this in most homes.

  • Fix

    Smart Queue assistant

    Works out the exact limits to enter in your router so downloads stop causing lag, then re-tests to prove it worked.

    Set up Smart Queue
  • FixPlus24/7 helper

    Automatic Smart Queue

    On OpenWrt, the helper turns Smart Queue on, tries 90, 85 and 80%, keeps what fixes lag and undoes everything if nothing helps.

    Let the helper do it
  • FindPlus24/7 helper

    Where is my lag?

    A small helper on your network times your router next to the internet, around the clock, and says whether lag starts at home, on the line or further out.

  • FixPlus24/7 helper

    Best hours for big downloads

    Learns when your line is quietest, so updates and backups can run then instead of during your match.

  • FindNetPulse DNS

    Who is downloading?

    Shows which device started a big game, update or backup download, and names it in lag alerts. Counts the service, never the site.

  • Find

    Streaming check

    Records your speed every second for 30 seconds, so you see the dips that make video blur or buffer, not just the average.

Beyond your line
