What do your modem's lights show?

Try these steps

  1. Restart the modem: unplug its power for 30 seconds, plug it back in, and wait 3 minutes.
  2. Move closer to the modem, or test with a LAN cable. Walls and floors weaken Wi-Fi.
  3. Pause big downloads, updates, and videos on the other phones and computers in the house.
  4. Check Advisories in case there's maintenance in your area.
