# Why Does My Bios Ask For My Altitude: Understanding and Configuring Cisco 5520 Wireless Controller in Your Homelab

Welcome to this comprehensive guide on configuring your Cisco 5520 Wireless Controller, a valuable addition to any homelab or self-hosted environment. In this tutorial, we will delve into the mysteries of why your BIOS asks for the altitude of the system and guide you through the installation, setup, configuration, usage, and troubleshooting steps of this versatile device.

Prerequisites

• Hardware: Cisco 5520 Wireless Controller (Wireless LAN Controller Module 3 - WLCM3)
• Software: Cisco Prime Infrastructure 3.8.x or higher
• Network Requirements: Static IP address, VLAN configurations if necessary, and access to the controller’s management network
• User Permissions: Administrator-level privileges on your Cisco Prime Infrastructure

Installation & Setup

1. Install Cisco Prime Infrastructure according to the official documentation.

2. Register your Cisco 5520 Wireless Controller to Prime Infrastructure following the registration instructions.

3. Configure the controller’s settings, including the altitude, in Prime Infrastructure under Wireless > Wireless Controllers > [Controller Name] > Controller Properties.

4. Verify the controller’s registration and configuration by navigating to Wireless > Monitor > Controllers > [Controller Name].

Configuration

1. Secure your Cisco 5520 Wireless Controller by enabling encryption, setting strong passwords, and configuring role-based access control (RBAC).

2. Optimize performance by adjusting channel width, band steering, and load balancing settings according to your network’s needs.

3. Integrate the controller with other services such as RADIUS authentication servers or network management platforms.

4. Customize the controller for different use cases, such as guest access or IoT deployments, by configuring policies and profiles.

Usage & Operations
