Here we take a look at everything relating to Wi-Fi. We start with the history of Wi-Fi and why it has become second nature in our daily lives. We also dive in to how it works and how you can improve your speed and the distance it can reach. Then finally we take a look at how you can do some fault finding yourself and find ways to resolve most problems before you have to start considering those dreaded long call queues to your provider for help.

How to Improve Your Wi-Fi

Move Your Router to a Central Location:

Why: Reduces signal interference and improves coverage throughout your home.

How: Place your router in a central, open area, away from thick walls, metal objects, or appliances that emit electromagnetic waves (like microwaves). The fewer physical obstacles in the way, the better your signal strength will be.

Update Your Router Firmware:

Why: Ensures you have the latest security patches and performance optimizations.

How: Check your router’s manual or manufacturer’s website for instructions on updating firmware. Many modern routers have an option to check for and apply updates directly in the settings interface.

Use a Wi-Fi Extender or Mesh System:

 Why: Expands your network’s range, eliminating dead zones in larger spaces.

How: If you have a large home or areas with weak signal strength, invest in a Wi-Fi extender or mesh system. Extenders amplify the signal, while mesh systems use multiple access points to create a seamless network across your space.

Limit Devices and Bandwidth-Hogging Apps:

Why: Reduces network congestion, improving speed and stability for all connected devices.

How: Prioritize essential devices and apps. You can log into your router settings to see what’s connected and limit unnecessary devices. Use Quality of Service (QoS) settings to give priority to high-demand activities like video calls or gaming.

Upgrade to a Modern Router (Wi-Fi 6 or 7):

Why: Provides faster speeds, better efficiency, and handles more devices at once.

How: If your router is more than five years old, it might be time for an upgrade. Wi-Fi 6 and 7 routers offer better performance, especially in homes with many connected devices. Look for features like MU-MIMO, beamforming, and dual or tri-band capabilities for the best results.

1. Slow Internet Speeds

Common Causes:

• Too many devices connected
• Router placement or interference
• Outdated hardware or firmware

Fixes:

• Restart the Router: Unplug for 30 seconds and plug it back in.
• Move Closer to the Router: Walls and distance weaken signals.
• Limit Connected Devices: Disconnect unused devices.
• Update Firmware: Check router settings or manufacturer website.
• Upgrade Equipment: If your router is old, consider upgrading.

3. No Internet Connection

Common Causes:

• ISP outages
• Faulty cables or connections
• Incorrect router settings

Fixes:

• Check ISP Status: Use your mobile data to check for outages.
• Inspect Cables & Connections: Make sure everything is plugged in properly.
• Reboot Devices: Restart your modem, router, and device.
• Reset Router: Press the reset button (hold for 10 seconds).

5. Forgotten or Incorrect Wi-Fi Password

Common Causes:

• Forgot password
• Typing errors or case sensitivity

Fixes:

• Check Router Label: The default password is usually on the router.
• Access Router Settings: Log in via browser (type the router IP, usually 192.168.1.1) and reset the password.

7. IP Address Conflicts

Common Causes:

• Two devices with the same IP address
• Router struggling to assign IPs

Fixes:

• Restart Router: This forces the router to reassign IPs.
• Set Static IP: Manually assign unique IP addresses in router settings.

1. Slow Internet Speeds

Common Causes:

• Too many devices connected
• Router placement or interference
• Outdated hardware or firmware

Fixes:

• Restart the Router: Unplug for 30 seconds and plug it back in.
• Move Closer to the Router: Walls and distance weaken signals.
• Limit Connected Devices: Disconnect unused devices.
• Update Firmware: Check router settings or manufacturer website.
• Upgrade Equipment: If your router is old, consider upgrading.

2. Wi-Fi Keeps Disconnecting

Common Causes:

• Interference from other devices (microwaves, Bluetooth)
• Router overheating or hardware issues
• Network congestion

Fixes:

• Reposition the Router: Keep it in a central, elevated location.
• Switch Wi-Fi Channels: Use router settings to switch to a less crowded channel.
• Use 5 GHz Band (if supported): Less interference than 2.4 GHz.

3. No Internet Connection

Common Causes:

• ISP outages
• Faulty cables or connections
• Incorrect router settings

Fixes:

• Check ISP Status: Use your mobile data to check for outages.
• Inspect Cables & Connections: Make sure everything is plugged in properly.
• Reboot Devices: Restart your modem, router, and device.
• Reset Router: Press the reset button (hold for 10 seconds).

4. Weak Signal in Certain Areas

Common Causes:

• Distance from the router
• Thick walls or physical obstacles

Fixes:

• Relocate the Router: Place it in a more central location.
• Use a Wi-Fi Extender or Mesh System: Expands signal coverage.
• Reduce Interference: Keep away from electronics and thick walls.

5. Forgotten or Incorrect Wi-Fi Password

Common Causes:

• Forgot password
• Typing errors or case sensitivity

Fixes:

• Check Router Label: The default password is usually on the router.
• Access Router Settings: Log in via browser (type the router IP, usually 192.168.1.1) and reset the password.

6. Device Can’t Find Wi-Fi Network

Common Causes:

• Hidden SSID (network name)
• Router issues

Fixes:

• Restart Router & Device: Simple, but effective.
• Manually Add Network: On your device, manually add the Wi-Fi name and password.
• Check Router Settings: Make sure the SSID isn’t hidden.

7. IP Address Conflicts

Common Causes:

• Two devices with the same IP address
• Router struggling to assign IPs

Fixes:

• Restart Router: This forces the router to reassign IPs.
• Set Static IP: Manually assign unique IP addresses in router settings.
