A user reports that their computer is not connecting to the Internet. After checking that the computer has a valid IP address, you suspect the issue could be with the computer's network card. You replace the network card, but the computer still can't connect to the Internet. What should you do next?
Establish a new theory, such as checking the network cable or router, and test it.
Assume that the Internet service is down and wait for it to come back on its own.
Replace the network card again with a different brand.
According to the CompTIA troubleshooting methodology, when an initial theory is not confirmed after testing (in this case, replacing the network card did not resolve the connection issue), the next step is to establish a new theory and test it, or escalate the issue. Escalating is a common practice when a resolution cannot be found with the available resources or knowledge, allowing someone with more expertise or different resources to assist. The other options are incorrect because they either involve repeating a failed test without new information, jumping to a drastic and unfounded conclusion, or taking a passive approach instead of actively troubleshooting.
