Why is my internet slow? 10 fixes to try

Slow internet is caused by your plan, your Wi-Fi, your devices or your provider's network. Work through these steps in order.

  1. Run a speed test. Use our speed test and note the download, upload and latency.
  2. Test on a wired connection. Plug a computer into the router with an Ethernet cable. If wired speed is fine but Wi-Fi is slow, the problem is your Wi-Fi.
  3. Restart the modem and router. Unplug both for 30 seconds, plug in the modem first, then the router.
  4. Check how many devices are busy. Large downloads, cloud backups, game updates and several 4K streams can use up a plan. Pause them and retest.
  5. Move the router. Put it in a central, open location, off the floor and away from microwaves, cordless phones and thick walls. See our Wi-Fi tips.
  6. Use the 5 GHz or 6 GHz band for devices close to the router. They are faster than 2.4 GHz over short distances.
  7. Check your equipment's age. Older modems and routers may not support your plan's speed. Check the model's maximum speed.
  8. Look for an outage. Check your provider's status page or app, or ask neighbors with the same provider.
  9. Compare to your plan. If speeds are consistently far below what you pay for, contact support with your test results.
  10. Consider whether your plan is too small. Use the speed calculator. If you need more, see what is available at your ZIP code.

When to call your provider

Call if wired speed stays far below your plan after restarting equipment, if the connection drops repeatedly, or if the modem shows error lights. Have your speed test results ready. Ask them to check the signal on your line and whether your equipment is up to date.
