Common causes of slow Wi-Fi
Weak signal, interference, crowded channels, old devices, outdated router software, too many simultaneous downloads, and provider problems can all reduce perceived internet speed.
How to narrow it down
- Test near the router. If the speed improves substantially, your biggest problem may be coverage.
- Test on a second device. One slow phone or laptop may need a software or network reset.
- Compare wired and wireless speed. Wired performance can help distinguish Wi-Fi issues from internet-service issues.
- Check router updates and placement. Simple changes sometimes make a noticeable difference.
- Review the equipment age. An older router may struggle with a busy household, but upgrade only after diagnosing.
