Simple Troubleshooting Network Performance Issues for Office Users

Troubleshooting Network PerformancePrior to the LiveNX solution, it was almost impossible to have a network be in perfect working conditions for a long period of time. In the absence of absolutely perfect network performance, errors are bound to occur; luckily, as in most cases, NetOps professionals in your organization can easily troubleshoot network performance once the error source has been detected, a core strength of LiveNX.

While requesting the services of a network engineer might always be the best option if you want to get back to your business ASAP, it might be worth it to have basic knowledge on how to troubleshoot network performance without breaking a sweat. That is if the error in question is one within your control.

Taking the First Step: Have an understanding of the Problem

Finding and troubleshooting network performance issues can be frustrating – network performance problems are one of the top complaints by employees. The key to quick resolution is to remain calm and assess the situation wholly and determine if the problem is something within your control. Whenever a network performance degrades, there is always the probability that a hundred questions can be asked before one can determine or identify the problem, the cause of the problem and how to troubleshoot it. Take a slow network as an example; one may ask:

  • Who is experiencing the slowness, the end-users, or the internal staff?
  • Is the slowness on a WAN or LAN network environment?
  • What type of internet connection is being used?
  • What types of switches are in use?
  • Those that reported the slow network, are they all in the same segment?

Depending on the issue in question, asking relevant questions will enhance an understanding of the problem, subsequently paving the way for appropriate solutions to be implemented in troubleshooting network performance.

Troubleshooting Network Performance Issues

Reboot
Sometimes, the problem is not as big as you might have imagined it to be – it might not be your network but rather applications on your computer. (Network Operations faces this all the time too). A lot of time can be wasted trying out various solutions when the problem is a temporary one that can be easily fixed by a power down / up cycle. Turn off computers for about 60 seconds is the easiest first step in troubleshooting network performance issues for an end-user.

Hardware Inspection

If a problem persists after a reboot, a manual check can be conducted to ensure that cables are properly connected and that the LED link lights indicate that the NIC is actively connected to the network device. If otherwise, it is possible that the NIC is improperly connected to a faulty network port or that the network adapter has been disabled or it doesn’t have an active connection. If the network adapters are configured properly, it is likely that the NIC is faulty and due for replacement.

Still, on hardware, a persistent network issue can also be as a result of a piece of network equipment that has outlived its lifespan, or it is not particularly compatible with the new complexities of today’s networks. If you feel they are outdated, it might be best to consult an IT professional before taking the next action.

Or if using a wireless network, check to see if you are connected to the wireless network in your office.

IP Configuration
Till date, poor IP configuration resulting from the use of wrongly configured domain name servers (DNS) stands as one of the most common sources of poor network performance issues. You can troubleshoot network performance errors of this kind by setting your network connection to obtain an IP address automatically.

Follow these steps:

Open network and sharing center -> Connections -> network in use (whether wired or wireless) -> Properties -> double click on IPv4 or IPv6 -> Adjust settings to obtain DNS server address
and IP addresses automatically.

To confirm that you have started receiving a correct IP address, type “ipconfig” into the command prompt and check out for the text under the WLAN adapter or Ethernet adapter. If the IP address being displayed starts with 169.x.x.x, then it is safe to conclude that your device is not receiving a valid IP address from the router. To troubleshoot the problem, type the following
commands.

Ipconfig /release    

Ipconfig /renew

In a case where the command prompt does not fix the problem but plugging the computer directly into the modem did fix it, then the problem can be said to be a router problem. 

Ping and Trace

Having an IP address that doesn’t start with 169 implies that you have a valid IP address. By implication, this means that if you are experiencing a poor network performance, then the problem is probably stationed between the internet and the router. There are numerous tools online that allow you to ping and trace. Additionally, there are numerous tools for wireless network speed tests. Just Google “free ping and trace tools” or “free network speed test.”

Troubleshoot Network Performance Issues Requires Pros

Fix Network Performance Issues As much as it might sound exciting to sit down and start checking out numerous possibilities that might be the cause of your office’s network problems; it will most likely end up being a tedious task.  The complexity of network systems today creates a whole new possibility in the development of network performance errors. An error can arise as a result of malfunctions in various components within the network. Hours that should be spent boosting productivity in the office, are rather spent figuring out the cause of poor network performance. 

LiveAction’s LiveNX solution is a network monitoring tool that addresses common and complex network problems seamlessly, through the prioritization of network activities (voice, video, critical applications, etc.,) that are most important for smooth running of an organization’s daily affairs. 

As an efficient means of troubleshooting network performance errors, the solution package effectively keeps NetOps staff a thousand steps ahead, by enabling them to effortlessly troubleshoot network performance errors not limited to:

  • Over-utilization by numerous network-based applications
  • IP and DNS errors
  • Network discovery and mapping errors
  • Bandwidth Hogs

Simply put, with a unified network monitoring dashboard feeding your IT managers with reports on the physical and virtual components of your network system, your organization gets to proactively identify network performance issues before they even occur. There is no simpler way to ensure that you offer the best user experience while keeping your staff optimally productive without network frustrations.
