Network downtime can significantly impact your business, from decreased revenue and productivity to damaged reputation and customer service. But even slow network performance can disrupt operations and hinder the adoption of emerging technologies. In today’s business landscape, network reliability is critical to success, and any decrease in performance can come with significant costs.
Effective network performance is not just about increasing bandwidth. Although bandwidth limitations can create bottlenecks that impact performance, adding more bandwidth as a reactive measure may only mask underlying issues and exacerbate the problem over time. Denver IT Support experts have access to performance monitoring tools to detect, diagnose, and solve network issues before they become major problems.
Here are the most common network issues and their solutions.
5 Most Common Network Issues and Solutions
- Slow Internet Performance
Slow network performance can be frustrating and often caused by congestion or poor-quality connections. Even if you have dedicated bandwidth, a single overloaded port on a switch or router can significantly decrease network performance. This is particularly true for leased lines, where speed tests may show that the network is not reaching its rated potential. In some cases, poor-quality connections that have corroded or deteriorated can also be to blame.
To get accurate results about your internet speed, try conducting speed tests using websites that test from geographically remote servers. It will help identify any areas of congestion on your ISP’s network. If you have cable internet, it’s important to note that your local network is shared amongst your neighbors. This means that your ISP must commit to a costly bandwidth upgrade if there is saturation. If you identify any issues, report your findings to your ISP so they can take steps to resolve the issue.
- DNS Issues
DNS (Domain Name System) is a directory for the Internet and devices. It matches domain names with their corresponding IP addresses. Each website has its unique IP address on the web, and computers can connect to other computers via the Internet by looking up websites using their IP address. When you enter a domain name into your Internet browser, DNS works behind the scenes to find the relevant information connected to that domain.
DNS issues can be a frequent and easily overlooked problem in network systems. These issues can arise when you cannot connect to an IP address, indicating a potential network or internet access loss. For example, your website may appear online for you but offline for your visitors. Therefore, being aware of DNS issues is essential as they can significantly impact your online presence and connectivity.
- Unplugged Network Cables
Loose cables can cause big problems. It’s easy for them to slip out of their ports and disconnect your devices from the network. To avoid this, it’s essential to double-check your network cables before doing anything else. Coaxial cables, in particular, can be challenging to connect to your router as they require careful screwing into the port. Take your time and ensure they are correctly inserted to avoid connection issues.
To ensure that your hardwired ethernet connection is functioning properly, ensure the port is securely connected to both the wall output and your device. In addition, double-check that all ethernet cables stemming from your router are properly plugged into their respective ports. Finally, inspecting the ports for dust or debris that may interfere with the connection quality is also a good idea.
- High Bandwidth Usage
Is your internet bandwidth constantly drained due to multiple devices connected to your router? If so, you might be at risk of high bandwidth usage. This occurs when one or more devices consume a significant amount of your network’s bandwidth. For example, when a device downloads a large amount of content from the internet or when multiple devices perform bandwidth-intensive activities like streaming or gaming, you’re likely to experience high bandwidth usage.
To resolve the issue, begin with disconnecting and reconnecting your router. If the problem persists, consider updating your router’s software. To update the firmware, connect your router to your device using an ethernet cable and download the relevant update from the manufacturer’s website. Once downloaded, utilize the software to update your router. Ensure to restart your router afterward to ensure a successful upgrade.
- Local Network is Unable to Connect to the Internet
Dealing with external network problems can be challenging, especially when they occur intermittently or persistently. The most frustrating aspect of such issues is identifying the company responsible and then assigning the task of resolving the problem. This becomes even more difficult with intermittent failures that are hard to trace. Such a situation can be so vexing that organizations may have to change their internet service provider to resolve the issue.
To troubleshoot connectivity issues, start with a router and modem reboot. Next, use the tracert utility to pinpoint the location of communication breaks. Finally, examining the tracer results can identify the specific router hop causing the problem. Once you have identified the issue, contact your ISP with your findings and include screenshots to help expedite the resolution process.
Conclusion
Network issues can be frustrating and time-consuming, but they can be quickly resolved with the right knowledge and tools. Understanding the common network issues discussed in this article and following the recommended solutions ensures your network runs smoothly and efficiently. Whether you are dealing with slow internet speeds, connectivity problems, or security issues, taking a systematic approach to troubleshooting can save you time and effort. Remember to always keep your network infrastructure up to date and seek professional help if you encounter issues that require more advanced solutions. With these tips in mind, you can enjoy a seamless network experience and easily connect to the digital world.
