Answer :
When a person wants to connect to a wireless network at a cafe for the first time using a laptop, the laptop (wireless client) goes through several steps to establish a connection to the wireless network. These steps involve interacting with the wireless access point (AP). Understanding these steps is crucial for ensuring a successful connection.
Discover the AP:
- This is the first step. The wireless client must detect and identify the available wireless networks. The laptop will scan for and identify the signals transmitted by nearby access points. This process enables the client to discover the AP's presence and available networks, typically represented by SSIDs (Service Set Identifiers).
Authenticate to the AP:
- Once an AP is selected, the wireless client will attempt to authenticate with it. Authentication can involve traditional WEP, WPA, or WPA2 methods and includes providing a password or security key to verify the client's identity.
Associate with the AP:
- After successful authentication, the client sends an association request to the AP. If the AP accepts, it responds with an association response that allows the client to formally join the network.
Agree with the AP on the Payload:
- While payload agreement is not a distinct step in the connection process, it generally involves negotiating parameters for secure communication over the network.
In this context, the correct choice is the first option: 1. Discover the AP. This step is fundamental as it sets the stage for further communication and eventual connection to the network.
