Modern technology and the growing usage of hosted services have revolutionized network and application infrastructures. These changes have enabled users to access more features than ever before. However, they have also drastically increased our reliance on a well-functioning network to ensure the stability of these vital applications. Therefore, investing in and maintaining the appropriate network infrastructure and services is essential to ensure that our network and applications continue running smoothly.
When network issues or error occurs, the consequences can be disastrous. Knowing which network issues have the most potential to disrupt your network will help you identify potential network solutions. Employee Managed IT Services Los Angeles specialists to solve your network issues efficiently.
6 Most Common Network Issues and their Solutions
1. Slow Network Issues
Slow network performance is often caused by congestion on the local network. Speed tests, such as Internet speed tests, can help pinpoint areas of congestion and identify potential network connectivity solutions. Jitter, or disruption in real-time applications, is another common issue that can cause slow network performance. Latency measures how long it takes for data to reach its destination, while IP configuration issues can prevent a target IP address from being reached.
To troubleshoot slow network performance, you must check all possible sources of the issue and address each problem as it surfaces. Therefore, a thorough troubleshooting process is critical to resolving network issues quickly and efficiently.
2. Physical Connectivity Issues
Physical connectivity issues can be the source of slow internet performance. Cables or network adapters that are physically damaged or have deteriorated can lead to network disruption. Overloading a network can also lead to congestion, reducing bandwidth and traffic performance. When devices have software compatibility issues and different versions, the performance of IP data packets is affected. Additionally, improper configuration of IP addresses, subnet masks, and routing can lead to network-level troubleshooting issues.
When troubleshooting slow internet performance issues, it is essential to address all possible causes. By ensuring good physical connectivity, such as cable quality and port/interface functionality, network administrators can help ensure that users receive optimal internet service performance.
3. High CPU Usage
High network CPU usage is a critical network issue that calls for immediate attention. It can be caused by factors such as enormous traffic, processes taking longer to execute, and the large number of network packets being exchanged.
Because most devices use processors (such as CPUs) to process and route network packets, high CPU usage is often associated with sluggish network performance. One common cause of high network CPU usage is oversized data frames (frames with too much data). These large frames can consume a great deal of server processing power. Another factor causing high network CPU usage is server-side software that consumes significant server resources.
When troubleshooting network issues, focusing on hardware components specifically designed for handling heavy loads is essential. For instance, ASICs and NPUs on switches can help take responsibility off the CPU and process packets quickly. Poor physical connectivity can also lead to packet loss and reduced data flow through the network. Finally, high network CPU utilization increases drastically when packets are received and sent throughout the network.
4. VPN Connection Issues
VPN connection issues can be caused by the misconfiguration of Virtual Local Area Networks (VLANs). As a result, firewall settings may need to be adjusted to open the necessary ports. Additionally, issues may arise due to compatibility issues with software and version mismatches.
Configuration settings such as IP address, domain, authentication, and privilege can cause connection issues if not correctly configured. For example, such locations might include incorrect configurations of IP address, subnet mask, and routing IP address to the next hop on the network path. This might lead to network connectivity issues between two devices.
Improper configuration of IP addresses, subnet masks, and routing IP addresses can also cause network connectivity problems. Therefore, network administrators must configure network settings correctly to ensure network connectivity between devices.
5. Duplicate IP Addresses
A duplicate IP address is a common issue on a network. When two devices attempt to share a single IP address, an error “Address Already in Use” is displayed. This problem is caused by either a device with a router configured with static IP addresses or a server having two network adapters and being assigned the same IP address.
To fix this issue, first, disable the DHCP server on the new device or modify the router’s configuration so it assigns unique, static IP addresses near the top end of the subnet. You can also try using a different network address or ipconfig /release and ipconfig /renew to troubleshoot any other issues related to duplicate IP addresses on your network. Finally, you can also use ipconfig /all to troubleshoot any other problems associated with the same IP addresses on your web.
6. Malfunctioning Devices or Equipment
In most network devices, the software is installed. This software is critical to a network’s performance and should be updated. In addition, faulty hardware, such as routers, switches, and cables, can cause network performance issues. Therefore, it is essential to troubleshoot the most common network issues by performing basic troubleshooting techniques, such as checking network connection and troubleshooting internet connection issues.
Malfunctioning devices, such as firewalls, routers, switches, wifi APs, can lead to network issues due to wrong configurations or faulty connections. Misconfiguration of network devices can lead to network outages. You must check all devices’ settings and ensure they are configured correctly. Regular tests must be conducted on devices to ensure they work properly.
Maintaining a healthy environment is also vital for maintaining good network performance. It would be best to keep your devices and server clean and well-maintained to prevent any errors in functioning. Besides troubleshooting common network issues, you must also take note of any issues before they escalate into major problems with the network.
Conclusion
Although network connectivity is a problem that can impact the performance of your business, it is a problem that can be fixed in a short period. With the proper troubleshooting and network configuration practices, you can quickly troubleshoot and address network connectivity issues at their root cause.
