Slow Wi-Fi is frustrating, but the cause is often simple. Before you replace equipment or call your provider, try these steps in order.
Turn the router off, wait about thirty seconds and turn it on again. This clears many temporary problems. Do the same with your modem if you have a separate one.
Connect one device directly to the router with a cable and test it. If it is fast by cable but slow on Wi-Fi, the issue is the wireless signal. If it is slow on both, the problem may be your internet service.
Wi-Fi signals weaken with distance and obstacles. Try placing the router:
Other wireless devices and neighbours' networks can interfere. Many routers let you change the channel or choose between frequency bands. The faster band usually has shorter range, and the slower band reaches further. Check your router's instructions for how to change settings.
Phones, tablets, TVs, speakers and cameras all share your connection. If many devices are streaming or downloading at once, everything slows down. Disconnect devices you are not using.
Routers occasionally need updates for performance and security. Check the manufacturer's instructions on how to update, and consider changing the default admin password.
For devices that stay in one place, such as a desktop computer or TV, a cable is faster and more stable than Wi-Fi.
If some rooms still have a weak signal, you have options such as a Wi-Fi extender, a mesh system or powerline adapters. Each has trade-offs in cost, speed and setup. Compare options and check recent independent reviews.
If your household uses more devices or streams video in high quality, your plan may simply be too slow. Check the speed you pay for, compare it with a speed test, and ask your provider about options. Plans and prices change, so check current details.
Use a strong Wi-Fi password and the security setting recommended by the router. Unknown devices on your network can slow it down.
If nothing improves, contact your provider. Tell them what you have already tried, since it helps them diagnose the problem faster.
Restart, test by cable, move the router, reduce interference, disconnect extra devices, update, then consider new equipment only if needed.
