For networking problem solving I would start with the physical layer first, also known as the bottom-up approach. Starting from the bottom of the OSI model would allow me to verify any simple errors quickly, like comparing the suspect device with another to see if the problem persists, or simply powering the device on and off again. Following the OSI model cables would be checked for damage or being unplugged. If no issues were found physically, ports and software would be looked into next. Once the issue is found, figuring out how the problem occurred and try to recreate the problem to verify. To avoid any lengthy trial and error a plan to fix the solution would be made testing full functionality is restored. Documentation will need to be made on how the problem occurred and what steps were taken to correct the issue.
