Wi-Fi Quick Guide

Wi-Fi is a wireless networking technology that allows devices to connect to the internet and communicate with each other without the need for physical cables.

Wi-Fi uses radio waves to transmit and receive data between devices. It typically operates on the 2.4 GHz or 5 GHz frequency bands and uses the IEEE 802.11 standard.

A Wi-Fi access point is a device that acts as a central hub for Wi-Fi connections. It broadcasts a wireless signal that devices can connect to in order to access the internet or communicate with other devices on the network.

SSID stands for Service Set Identifier. It is the unique name assigned to a Wi-Fi network. When devices scan for available networks, they can identify and connect to a specific SSID to join a particular network.

To secure your Wi-Fi network, you can enable encryption (e.g., WPA2) to encrypt data transmitted over the network, set a strong password, change the default administrator credentials, and enable features such as MAC address filtering or disabling SSID broadcast.

Yes, you can extend your Wi-Fi range by using wireless range extenders or mesh Wi-Fi systems. These devices can amplify and extend the Wi-Fi signal to cover larger areas or eliminate dead zones within your home or office.

Wi-Fi signal strength can be affected by various factors, including distance from the access point, physical obstructions (e.g., walls), interference from other devices (e.g., microwaves or cordless phones), and the number of connected devices sharing the network.

Dual-band Wi-Fi refers to routers or devices that support both the 2.4 GHz and 5 GHz frequency bands. It allows for better performance and less interference when multiple devices are connected, as they can utilize different frequency bands.

Yes, most mobile phones today support Wi-Fi connectivity. You can connect your phone to a Wi-Fi network to access the internet, download apps, stream media, and more, often providing faster and more stable connections than cellular data.

Wi-Fi operates within a safe range of radio frequency emissions as defined by regulatory bodies such as the FCC. Extensive research has not found any conclusive evidence linking Wi-Fi to adverse health effects at normal exposure levels.
