When configuring a Wi Fi network, which option best describes the basic steps and the role of common Wi Fi protocols?

Introduction / Context:
Wi Fi has become the standard way to connect laptops, phones, and other devices to local networks and the internet without cables. Configuring a Wi Fi network correctly is important for security, performance, and compatibility. This question asks you to identify the essential configuration steps and to understand the role of Wi Fi protocols, such as those based on IEEE 802.11 standards and security mechanisms like WPA2 and WPA3.

Given Data / Assumptions:
- A wireless router or access point is available to broadcast the network.
- The administrator can log in to the router configuration interface.
- Clients such as laptops and smartphones will connect through Wi Fi.
- Security and compatibility with common devices are required.

Concept / Approach:
A Wi Fi network configuration starts with defining a network name SSID so that users can identify it. Then you choose a wireless mode based on IEEE 802.11 standards, such as 802.11n or 802.11ac, which determine speed and frequency band options. The next critical step is to choose a security protocol, typically WPA2 or WPA3, and set a strong password. Clients then scan for the SSID, authenticate using the chosen security protocol, and use the Wi Fi radio protocols to exchange data over the air.

Step-by-Step Solution:
Step 1: Access the router or access point configuration page, usually through a web interface. Step 2: Set the SSID, which is the human readable name of the Wi Fi network. Step 3: Choose the wireless mode and channel, selecting standards such as 802.11n, 802.11ac, and appropriate frequency bands. Step 4: Configure security by choosing WPA2 or WPA3 and setting a strong pre shared key or using enterprise authentication if available. Step 5: On client devices, enable Wi Fi, select the SSID from the list of available networks, enter the password, and confirm that the connection is established.

Verification / Alternative check:
You can verify a correct configuration by checking that the SSID appears in client Wi Fi lists, that entering the password allows connection, and that the link uses the expected security type. Many routers show connected clients and the used 802.11 protocol, which confirms that you selected the correct mode and security. Internet access or internal resource access further validates the configuration.

Why Other Options Are Wrong:
Option B is wrong because laptops do not require wired modem drivers to use Wi Fi, and the network still needs an SSID and security. Option C is incorrect since Wi Fi does not convert all traffic into email attachments. Option D is unsafe and false because Wi Fi protocols support strong encryption and authentication through WPA and WPA2 or WPA3, and disabling security exposes the network to unauthorized access.

Common Pitfalls:
Common mistakes include leaving the default SSID and password unchanged, using outdated or insecure protocols like WEP, or choosing crowded channels that cause interference. Another pitfall is mixing incompatible modes that limit performance, such as forcing the router to legacy standards when all clients support faster protocols. Good practice is to use WPA2 or WPA3, strong random passwords, and appropriate channels and bands for the environment.

Final Answer:
To configure a Wi Fi network, you define an SSID, choose security such as WPA2 or WPA3 with a strong password, select an IEEE 802.11 mode like 802.11n or 802.11ac, and then connect client devices using those wireless protocols.
