Why is my internet slow? 10 fixes that work

Updated: 11 October 2026

First, run a speed test so you know the number you start from. Then work down this list.

On mobile data

  1. Check your daily data. Many prepaid plans cut the speed sharply once the day's high-speed data is used.
  2. Turn airplane mode on and off. The phone reconnects to the best tower.
  3. Check the network type. If it shows 3G or E, set the preferred network to 4G or 5G.
  4. Move near a window. Walls and basements weaken the signal a lot.
  5. Test at another time. Evening slowdowns usually mean a crowded tower.

On WiFi

  1. Test next to the router. If it is fast there, the problem is WiFi reach, not your plan.
  2. Use 5 GHz nearby and keep 2.4 GHz for far rooms.
  3. Restart the router and update its firmware.
  4. Move the router to a central, high, open spot.
  5. Find the bandwidth hog: cloud backup, game updates and 4K TVs can take most of the line.

Still slow on a cable next to the router at different times? Note your results and contact your provider; see how to complain.
