Answer:
Step-by-step explanation:
Replacing the cable should already solve the problem, if it does not then you need to check to make sure that the wall plate is properly accessing the office network directly through the cable. As well as making sure that the wall plate's cable to the network is not damaged. If the cable is fine, then your last step would be to give the user's computer a new IP address as it may be interfering with another address in the network, hence it is not receiving data. That should fix the problem.
