How to Fix Slow Wi-Fi at Home

Why Is My Wi-Fi Slow?

Slow Wi-Fi is one of the most common tech complaints we hear. The good news is that most causes are easy to fix yourself. Work through the steps below before calling your internet provider.

Step 1 — Restart Your Router & Modem

This is the single most effective fix. Unplug both your modem and your router from power, wait 30 seconds, then plug the modem in first. Once its lights stabilise, plug the router back in.

Step 2 — Check How Many Devices Are Online

Every device on your network shares the same bandwidth. Log in to your router admin page (usually 192.168.1.1 or 192.168.0.1) and look at the connected devices list. Streaming 4K video on three TVs while everyone works from home will slow things down.

Step 3 — Move Closer to the Router

Wi-Fi signal drops off quickly through walls and floors. If your device is far from the router, try moving it closer to test whether speed improves. If it does, consider a Wi-Fi extender or a mesh network system (e.g., Eero, Google Nest Wi-Fi).

Step 4 — Change Your Wi-Fi Channel

Routers broadcast on channels and neighbouring routers can cause interference. Log in to your router settings, go to Wireless Settings, and switch from Auto to a specific channel — try 1, 6, or 11 for 2.4 GHz, or any channel for 5 GHz.

Step 5 — Run a Speed Test

Visit speedtest.net and run a test. Compare the result to the speed on your internet plan. If you are getting much less than you are paying for, the problem may be with your ISP, not your equipment.

Step 6 — Check for Background Downloads

Windows Updates, app downloads, and cloud backup software can quietly consume your entire bandwidth. Check Task Manager → Performance → Wi-Fi (Windows) or Activity Monitor → Network (Mac) to see what is using the most data.

Step 7 — Consider a Router Upgrade

Routers older than 4–5 years may not support modern Wi-Fi standards (Wi-Fi 6 / 802.11ax). A newer router can dramatically improve speed, range, and reliability — especially in larger homes.
