Common issues with wireless LAN controllers and how to troubleshoot them with effective monitoring

To keep up with competition, enterprises must embrace next-level capabilities like artificial intelligence, machine learning, and the Internet of Things (IoT). Market leaders know this depends on having fast, resilient, reliable, and secure connectivity that can adapt to the business's needs. 
Organizations have to ensure their:
  • Network aligns with enterprise needs and delivers value end-to-end. 
  • Wireless ecosystem integrates across the enterprise's technology stack—including hardware, software, and physical infrastructure.
Wireless networks are bringing in connectivity to all industries. Yet, ensuring consistent and reliable Wi-Fi connectivity is no small feat. Wireless LAN controllers (WLCs)—which manage your network's access points from a cocktail of vendors—can, at times, be the source of headaches.

This is where Site24x7's network monitoring tool comes in. It offers actionable insights and advanced features to keep your network running smoothly. 

In this blog, we will discuss WLCs and how Site24x7 can assist you in monitoring them.

What are wireless LAN controllers and why are they crucial?

Wireless LAN controllers act as the nerve center of an enterprise Wi-Fi network. They manage access points (APs), optimize traffic, enforce security policies, and ensure a consistent user experience. While indispensable, WLCs are prone to various issues that can compromise your network's reliability and performance.

Common issues with wireless LAN controllers

  1. AP disconnections: Frequent disconnections between WLCs and access points can disrupt connectivity, especially in high-density environments like offices, airports, and hospitals.
  2. Overloaded controllers: A single WLC managing too many APs or client devices may struggle with performance, leading to slow network speeds and intermittent outages.
  3. Firmware compatibility issues: Outdated or mismatched firmware versions can result in inconsistent performance, security vulnerabilities, and compatibility issues with newer devices.
  4. Interference and signal degradation: Environmental factors like physical obstructions, overlapping channels, and interference from other devices can degrade wireless signals and affect end-user experience.
  5. Configuration errors: Misconfigured settings in the WLC can result in authentication failures, improper traffic routing, and other network hiccups.
  6. Security vulnerabilities: Without proper monitoring, rogue APs, unauthorized access, and data breaches can compromise your network's integrity.
