To  manage a Wi-Fi router WAN links that serve them are usually the most expensive part of the network, and managing bandwidth allocation can be complex. Over-subscribing to bandwidth could mean that the company is paying for more bandwidth than required and under-subscribing could result in congestion and unacceptable network performance. WAN monitoring and Router monitoring thus become very critical to not just day-to-day productivity but also to a company's bottom-line. Network managers will need to optimize the quality of service by balancing throughput.
