📊 Test Your Current Speed

Before you start how to improve wifi speed without buying new hardware, test your current speed.

How to Test:

1. Run a wifi speed test on your device (Ookla Speedtest or Fast.com).
2. Test with a wired connection (Ethernet) first.
3. Test with WiFi in different rooms.
4. Note the speeds.

What to Look For:

• Wired speed: Your actual internet speed.
• WiFi speed: Your WiFi performance.
• Difference: If WiFi is much slower, the problem is your WiFi.

Why This Matters:

You need a baseline to measure improvement. After making changes, test again to see if your wifi speed has improved.

For more on testing, see our how to test WiFi speed guide.

📍 Optimise Router Placement

Router placement is one of the most effective wifi speed boost tips.

Why Placement Matters:

Where you place your router affects signal strength and wifi speed. A poorly placed router creates dead zones and slow speeds.

Golden Rules:

• Central location: Place the router in the centre of your home.
• Elevated: Place it on a shelf or high table.
• Away from walls: Keep it at least 0.5 metres from walls.
• Away from metal: Metal objects block signals.

What to Avoid:

• Corners: Wastes half the signal.
• Floors: Signals travel outward and downward.
• Cupboards: Blocks the signal.

Realistic Example:

Moving your router from a corner to the centre of your home in Pretoria East can improve wifi speed by 30-50%.

For more on placement, see our router placement guide.

📡 WiFi Channel Selection

Wifi channel selection is a key part of wifi network optimisation.

Why Channels Matter:

If too many routers use the same channel, they interfere. This slows down your wifi speed.

How to Choose the Best Channel:

1. Download a WiFi analyser app.
2. Scan for nearby networks.
3. Identify the least congested channel.
4. For 2.4 GHz, use channels 1, 6, or 11.
5. Change the channel in your router settings.

How to Change Your Channel:

1. Access your router settings.
2. Find wireless settings.
3. Find channel selection.
4. Select your chosen channel.
5. Save and reboot.

Realistic Example:

Changing the channel can improve wifi speed by 10-30% in congested areas.

For more on channels, see our router channel settings guide.

🚫 Reduce Interference

Interference is a common cause of slow wifi speed.

Common Interference Sources:

• Microwaves: Operate on 2.4 GHz.
• Cordless phones: Use 2.4 GHz.
• Baby monitors: Use 2.4 GHz.
• Neighbouring WiFi: Too many routers.
• Bluetooth: Can interfere.

How to Reduce Interference:

• Move the router: Keep it away from interference sources.
• Use 5 GHz: Less interference than 2.4 GHz.
• Change channels: Reduce interference from neighbours.

Realistic Example:

Moving your router away from the microwave in Waterkloof can improve wifi speed during microwave use.

For more on interference, see our WiFi interference guide.

⚙️ Update Router Firmware

Updating firmware is a simple wifi speed optimisation step.

Why Firmware Matters:

Router manufacturers release updates that improve performance, fix bugs, and enhance security.

How to Update:

1. Access your router settings.
2. Find “Firmware Update” or “System Update.”
3. Check for updates.
4. Install if available.
5. Wait for the router to reboot.

How Often to Update:

Check every 3-6 months. Some routers have automatic updates.

Realistic Example:

A firmware update in Menlyn can improve wifi speed by fixing known bugs.

For more on firmware, see our router setup guide.

📊 Enable QoS

QoS is a powerful tool for wifi network optimisation.

What Is QoS?

QoS (Quality of Service) prioritises certain types of traffic. This ensures important activities get priority.

How to Enable QoS:

1. Access your router settings.
2. Find QoS or bandwidth management.
3. Enable QoS.
4. Set streaming or gaming as high priority.
5. Save and apply.

Why QoS Helps:

If someone is downloading large files while you’re streaming, QoS ensures your streaming gets priority. This improves your wifi speed for important activities.

For more on QoS, see our best router settings guide.

📱 Reduce Connected Devices

Too many devices can slow down your wifi speed.

Why This Helps:

Each device uses bandwidth. The more devices, the less bandwidth each device gets.

How to Reduce Devices:

• Disconnect unused devices: Turn off WiFi on devices not in use.
• Use Ethernet: Connect stationary devices via Ethernet.
• Use guest network: Isolate guest devices.

Realistic Example:

Disconnecting 5 unused devices in Lynnwood can improve wifi speed for active devices.

For more on device management, see our WiFi for many devices guide.

📡 Use 5 GHz Band

Using the 5 GHz band is a key wifi speed boost tips technique.

Why 5 GHz Is Faster:

• Less interference: Fewer devices use 5 GHz.
• Faster speeds: Supports higher speeds.
• Less congestion: Fewer networks on 5 GHz.

How to Use 5 GHz:

1. Check if your device supports 5 GHz.
2. Connect to the 5 GHz network.
3. Use 5 GHz for streaming, gaming, and video calls.

Note: 5 GHz has shorter range. Use 2.4 GHz for distance.

For more on bands, see our dual band WiFi guide.

🔑 Change WiFi Password

Changing your password can improve wifi speed.

Why This Helps:

If someone is using your WiFi without permission, they’re using your bandwidth. Changing the password kicks them off.

How to Change Your Password:

1. Access your router settings.
2. Find wireless or WiFi settings.
3. Change the WiFi password.
4. Use a strong password.
5. Save and apply.
6. Reconnect all your devices.

Important: Use a strong password with at least 12 characters.

For more on passwords, see our best security settings guide.
