You may think that this problem is due to a network failure, or Internet connection problem, but it’s actually because you have a broken or malfunctioning cable.
Hardware problems like defective cables or connectors can generate network errors on the network equipment to which it is connected. When the time comes to troubleshoot network issues, our instinct is often to think about the most complex situations, when sometimes the problem is actually very simple and right in front of us. It may seem obvious, but some network issues may occur with the hardware outside of the network. Several monitoring tools such as those included in the equipment's GUI or a poorly configured monitoring tool can report an average value on the use of 8 cores or over too long periods, such as every 5, 15 or 60 minutes. It can sometimes be difficult to gather the right information about the actual use of CPU. If overused, network metrics like latency, jitter, and packet loss will increase, which will lead to significant levels of network performance degradation. Depending on the features that you’ve enabled on your devices, the CPU may be in the critical path of packet routing or forwarding. For this equipment, the CPU usage is not linked to the amount of traffic.įor equipment that analyzes or manipulates traffic, like firewalls, that's a whole different story. There are a number of network devices such as switches that have hardware components (ASICs or NPUs) that take charge and process packets super quickly. CPU usage can increase drastically when processes require more time to execute or when a larger number of network packets are sent and received throughout your network. The most common reason for high CPU usage occurs when your network becomes bogged down by enormous amounts of traffic. With such a big job on its shoulders, the signs of high CPU usage on a network device are a very troubling sign for many of us.Īs your network devices continue to work harder to perform an increasing amount of tasks, it increases the chance that things can go wrong.

When this happens, you may start experiencing problems like slow download speed over the Internet.ĬPU, or “ Central Processing Unit”, is the primary component of a computer that receives and processes instructions for operating systems and applications. Network congestion caused by high bandwidth usage, also runs the risk of leaving insufficient amounts of bandwidth for other parts of your network that need it.
When someone or something, like a large application, on your network is monopolizing your bandwidth by downloading gigabytes worth of data, it creates a congestion in your network. Higher bandwidth allows data to be transferred across your network at a faster rate and can sustain a larger number of connected devices all at once.
Bandwidth is often mistaken for Internet speed when it's actually the volume of information that can be sent over a connection in a measured amount of time – calculated in megabits per second (Mbps). It refers to a network’s capacity to transfer data between devices or the Internet within a given span of time. That’s why it’s important to understand what can go wrong with your network and to continuously monitor network performance to quickly identify and fix network problems even before they affect your end-users.īandwidth is the maximum amount of data transmitted over an Internet connection in a given amount of time. Network problems are frustrating, and left unattended, they can have disastrous consequences for your business network. Some network problems can arise from faulty hardware, such as routers, switches, firewalls, and even from unexpected usage patterns, like network bandwidth spikes, changes in app configuration, or security breaches. There are many different network problems that can affect network performance. Anytime a bad network connection issues prevents you from accessing something outside your computer, you're likely dealing with a network problem. Network problems impact things like, VoIP calls, ERP applications, files downloads, and more. If you're struggling to perform everyday tasks over the Internet, or unable to use important apps, there's a good chance your network is to blame. Laggy video calls, slow application or network speed, buffering downloads, choppy VoIP Quality, and no Internet connection are examples of network problem symptoms.
