Final answer:
Option B is answer. To troubleshoot network connectivity issues on a Windows computer, check that the SOHO router is powered and the port LEDs show connectivity.
Step-by-step explanation:
To resolve limited or no network connectivity issues on a Windows computer, two important steps should be taken. First, verify that the SOHO router is powered on and that the corresponding port LEDs indicate there is connectivity. This will ensure that the hardware necessary to connect to the network is active and functioning.
Secondly, verify the network cable between the computer and router is connected and not damaged. A disconnected or faulty cable can often be the cause of network connectivity issues. Inspecting the cable and ensuring that it is properly plugged in at both ends, or replacing it if it's damaged, can solve the problem.
These steps are typically the first to consider before moving on to more complex troubleshooting procedures. Running tools like System Restore or configuring the system for safe mode may not directly address network connectivity issues and should only be considered if initial checks don't resolve the problem.
