Slow Internet — How to Actually Speed It Up

Slow internet can mean a dozen different things — a congested router, a failing cable, a background app hogging bandwidth, or simply a plan that no longer fits your household. This guide helps you pinpoint the real cause.

Step 1: Run a Speed Test

Open a browser and search for a free speed test (several are available from ISPs and independent providers). Run the test with Wi-Fi, then again with your computer plugged directly into the router with an Ethernet cable. If speeds are fine on Ethernet but slow on Wi-Fi, the wireless connection is the problem, not your internet plan.

Step 2: Restart Everything

Unplug your modem and router (they may be one unit). Wait 30 seconds. Plug the modem in first, wait for its lights to stabilise (about 60 seconds), then plug in the router. This clears temporary slowdowns more often than people expect.

Step 3: Check What Is Using Your Bandwidth

On Windows, press Ctrl + Shift + Esc to open Task Manager and click the Network column to sort by network usage. If an app like a game client, cloud backup, or video streaming service is consuming most of your bandwidth in the background, pause or limit it.

Step 4: Reduce Wi-Fi Interference

• Move the router away from microwaves, cordless phones, and baby monitors.
• Position it in a central, elevated spot — not inside a cabinet.
• If neighbours' networks are crowding the same channel, log into your router and change the Wi-Fi channel (channels 1, 6, or 11 on 2.4GHz cause the least overlap).

Step 5: Check for Background Updates

Windows Update, antivirus database downloads, and cloud sync (OneDrive, Dropbox, Google Drive) can all cap your speed temporarily. Check each and pause them during critical tasks.

Step 6: Check Your Cables

A cracked or loose coaxial or Ethernet cable between your wall and modem can halve your speed. Replace any cable that has visible kinks or damage.

When to Call Your ISP

If Ethernet speeds are consistently far below your paid plan (10% or more), contact your provider. Ask them to run a line test. You may have line noise, a failing modem, or simply an outdated speed tier. If you need a hand interpreting your results, feel free to ask us.
