What are the best network diagnostic tools?

In the realm of network diagnostics, a variety of tools are available, each designed to tackle specific aspects of network troubleshooting and analysis. From simple utilities for basic connectivity checks to advanced AI software and models for in-depth network analysis, the range of tools cater to a wide array of network diagnostic needs.

Network scanning tools

Network scanners are crucial for identifying devices connected to a network. They provide information about each device, including IP addresses, MAC addresses, and sometimes even the device type. These tools are essential for network mapping and understanding the layout of a network. Nile includes a built-in profiling feature that provides data about each device that is connected on the wireless and wired networks. 

Packet sniffers and analyzers

Packet sniffers and analyzers allow network administrators to inspect the data packets traveling through a network. This inspection can reveal issues like packet loss, unauthorized data transmissions, and bottlenecks in network traffic, offering deep insights into network performance and security. Nile has built integration workflows into our service that allow for use of 3rd-party tools. 

Network performance testers

These tools measure the performance of a network, including metrics like bandwidth, latency, and throughput. Network performance testers are vital for ensuring that the network meets the required performance standards for specific applications and services. Dedicated sensors and a radio in each access point probe the Nile Access network on a per minute basis. SLAs are provided for Availability, Coverage and Capacity. 

Configuration management tools

These tools help in tracking and managing the configurations of network devices. They are essential for ensuring that all devices adhere to the necessary standards and policies, and they play a key role in maintaining network security and efficiency. Nile is unique in this regard as each site is set up using a standardized model. There is no configuration per infrastructure device to track.

Wireless network tools

For wireless networks, specific tools are designed to analyze Wi-Fi signal strength, coverage, and interference. These tools are particularly important in optimizing the performance and coverage of wireless networks in various environments. Nile’s sensors play a role here as do AI and automation software and models built into the Nile Access Service.

Root cause analysis software

This software is designed to help network administrators identify the underlying causes of network issues. By analyzing network data and patterns, these tools can pinpoint the source of problems, leading to more effective troubleshooting. This is another area where Nile takes advantage of AI and automation software to help minimize troubleshooting efforts.

What are common network problems found after network diagnostics?

Network diagnostics often reveal a variety of common issues that can impact network performance and stability. Common problems found after running a network diagnostic include:

Bandwidth bottlenecks

Bandwidth issues can severely limit network efficiency, leading to slow performance and frustrated users. To fix this, increasing network capacity or optimizing network bandwidth usage through traffic management strategies can be effective. Nile actively monitors a deployment to ensure it is designed to handle user, IoT and application load with room for expansion.

High latency

Latency issues result in delayed data transmission, affecting applications that rely on real-time data. Solutions include optimizing routing paths, upgrading network hardware, or utilizing content delivery networks (CDNs) for better performance. Nile offers the ability to view potential issues and is the only vendor to offer a user-driven portal that allows users to directly test the performance of Internet connections without downloading 3rd-party applications. 

Security vulnerabilities

Uncovered security vulnerabilities pose a significant risk to network integrity and data safety. Addressing these requires implementing robust security measures like firewalls, anti-malware solutions, and regular security audits. Nile adheres to strict Campus Zero Trust security principles and has partnered with industry leading SASE / Zero Trust Network Access (ZTNA) security providers for remote access use cases.

Inconsistent network availability

Inconsistent network availability disrupts operations and reduces productivity. Enhancing network redundancy and implementing failover strategies can greatly improve network reliability. Availability is one of 3 areas where Nile offers SLAs and uses our standalone sensors and dedicated radios in each AP to test the network.

What are steps to troubleshoot network connectivity problems?

Below are some basics you can use to diagnose network connectivity problems. Keep in mind, the more complex your network, the more difficult it may be to find the root cause of a problem. 

Check physical connections

Ensuring all cables and hardware components are properly connected and functional is the first step in troubleshooting network issues. This simple check can often resolve many basic connectivity problems. Nile includes an AI–powered feature that automatically checks for broken cables, port flaps, etc.

Verify network configurations and settings

Incorrect network configurations and settings can lead to connectivity issues. It's crucial to review and correct these settings to ensure proper network operation. Due to the use of Nile’s standardized device setup, IT teams can eliminate the time spent in this regard. 

Run diagnostic tests

Using network diagnostic tools to run tests can help identify specific problems, such as issues with network throughput, capacity, or utilization, pinpointing areas that need attention. As previously mentioned, Nile performs sensor based tests every minute that are tied to SLAs to ensure Availability, Coverage and Capacity expectations are being met.
