You are midway through a 15 hour shift and you receive a call from an employee who turned on his computer and was unable to connect to the internet. As more employees arrived to work, computers that use the corporate Wi-Fi were unable to connect but the computers using a line (wired) were able to connect. The opposite side of the building and other floors were able to connect. There are other offices throughout the state and they all are having no issues in regards to internet or connectivity.

Prepare a brief contingency plan for this scenario.
