A user calls the help desk reporting that their laptop is experiencing limited connectivity when connected to the office's wireless network. The laptop successfully obtains an IP address but cannot access internal network resources or the internet. The user's smartphone, connected to the same wireless network, has full connectivity. Which of the following should the technician investigate FIRST to resolve the issue?
Check the Network Access Control (NAC) settings for any restrictions on the user's laptop.
Check if the Ethernet cable is securely plugged into the laptop.
Ensure that the laptop is connected to the correct SSID.
When faced with limited connectivity issues where the device receives an IP address but cannot access resources, checking Network Access Control (NAC) settings is a smart first step. NAC might be restricting the laptop based on certain security policies or compliance with the system's requirements. The incorrect answers involve either steps that are less likely to be the direct cause of the issue or should be performed after ensuring NAC settings are not the source of the issue. DHCP scope issues would not typically allow for IP address allocation, SSID mismatch would prevent the device from connecting to the wireless network entirely, and checking the Ethernet cable would not be relevant for a wireless connection.
