CompTIA A+ 220-1101 Practice Question
A user reports that their desktop is unable to reach any networked systems or the internet. You observe no signs of activity where the Ethernet cable connects to the computer. To best address this user's issue, what is the FIRST action you should take?
Procure a new computer's Ethernet interface as a direct replacement.
Reverse the Ethernet cable as it was likely installed backwards and the T568A side is plugged into the T568B port.
Inspect the physical Ethernet cable and its connections for any visible damage or to confirm if it's securely connected to the appropriate port on both the computer and the network switch.
Move the device to be closer to the wireless access point.
