Paying for a fast connection but still facing buffering and lag? In many homes the problem is not the internet line but the WiFi setup inside the house. Here are 10 simple, practical ways to fix slow WiFi and get the most from your broadband connection.
1. Run a Speed Test the Right Way
First, find out where the problem is. Connect a laptop to the router with a LAN cable and run a speed test. If the wired speed is good but WiFi is slow, the issue is your WiFi coverage, not the connection.
2. Place Your Router in a Central, Open Spot
WiFi signals weaken through concrete walls, floors and metal. Put the router in the middle of your home, at a raised height, away from cupboards, fridges and microwaves. Avoid hiding it in a corner or behind the TV.
3. Use the 5GHz Band
Most modern routers have two bands. 2.4GHz reaches further but is slower and more crowded. 5GHz is much faster at short to medium range. Connect phones, laptops and smart TVs near the router to 5GHz.
4. Change the WiFi Channel
In apartment buildings, many neighbours' routers use the same channel, causing interference. Log in to your router settings and try a less crowded channel, or set it to Auto.
5. Restart Your Router Regularly
A simple restart clears memory and fixes many temporary issues. Turn the router and ONU off for 30 seconds, then turn them back on.
6. Remove Unknown Devices and Use a Strong Password
If neighbours are using your WiFi, your speed drops. Check the connected-devices list in your router, change your password and use WPA2 or WPA3 security.
7. Limit Heavy Background Usage
Large game downloads, cloud backups, CCTV uploads and software updates can use most of your bandwidth. Schedule them for late night or limit them during work and study hours.
8. Add a Mesh System or Access Point for Big Homes
One router is often not enough for multi-storey houses. A mesh WiFi system or a wired access point on each floor gives strong, even coverage throughout the home.
9. Upgrade an Old Router
Routers older than 4–5 years may not support modern WiFi standards. A WiFi 5 or WiFi 6 dual-band router can make a big difference, especially on higher speed packages.
10. Keep Your Connection On During Load-Shedding
Power cuts switch off your ONU and router. A small mini-UPS designed for routers keeps you connected during outages so your work and classes are not interrupted.
Still Slow? Your Package May Be Too Small
As families add more phones, smart TVs and laptops, an older plan may no longer be enough. If several people stream or video call at the same time every evening, consider upgrading. Compare speeds and prices on our packages page.
