How to share a Wi-Fi connection securely

Written by  Dec 18, 2020

One major advantage 2.4GHz has over the newer 5GHz band is it penetrates solid objects more easily.

Since workstations and residential areas are mostly not devoid of objects, use 5GHz in tandem with 2.4GHz to get the best of both worlds.

How to boost Wi-Fi signal strength

Wi-Fi routers have far more limited transmitting power than cell towers or base stations. Plus, obstacles, like a wall or a piece of metal, can partially or completely block Wi-Fi signals. To maximise router efficiency, avoid placing it near or on the ground.

The ideal location for a router is an elevated spot near the centre of the room, as radio waves tend to spread out in a downward direction. And although Wi-Fi signals can easily pass through walls and ceilings, fewer obstacles often results in better transmission. Metal objects, mirrors and appliances that emit electromagnetic waves are strong disruptors of a Wi-Fi signal.

Avoid being an easy target to Wi-Fi hackers

Even with a password-protected network, remaining vigilant is key to preventing network intrusion and unauthorised access. Changing your router’s default password is a good place to start. Typically set by the device manufacturer, a router’s username and password are the same for all users.

More concerning, hackers can access a router’s credentials through a simple Google search about the brand. To maximise protection, access your router’s administration settings and set a strong password with numbers and special characters.

Also, disable auto-connect when joining a network and refrain from accessing, visiting, or avoid any website that doesn't start with https://, an essential security protocol.
