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.
