Study Notes
Troubleshooting WLAN Issues
- Dual-band routers/APs default to the same SSID for both 2.4 GHz and 5 GHz bands; renaming one can help segment traffic.
- Signal range can be improved by ensuring that the router/AP placement is unobstructed by furniture or tall appliances.
- When obstacles persist, consider using a Wi-Fi Range Extender or Powerline technology to enhance coverage.
Updating Firmware
- Regularly check for firmware updates on wireless routers and APs to fix common issues and address security vulnerabilities.
- Wireless LAN Controllers (WLCs) offer functionality to upgrade firmware across all managed APs.
- Use the WLC interface to set up SNMP, RADIUS, VLAN, DHCP, and WPA2 Enterprise WLAN configurations.
- Troubleshooting a WLAN often requires a systematic process to eliminate problems; common issues include connectivity loss and poor performance.
WLAN Configuration Basics
- Familiarize with essential terms like Network Address Translation (NAT), Wireless Mesh Network (WMN), port forwarding, and port triggering.
- To access AP information, navigate to the Access Points section on the interface to review system performance metrics such as IP address (e.g., 192.168.200.3).
- Active Cisco Discovery Protocol (CDP) on the network allows WLC to identify the AP connection details.
Advanced WLAN Configuration
- Access advanced settings on the Cisco 3504 Wireless Controller from the Summary page to explore all configuration features.
- Web browsers can be used to log in to wireless routers; change default credentials for security right after gaining access.
- Default router configurations are easily accessible online; ensure to modify default settings for enhanced security.
Basic Network Setup for Remote WLAN
- Steps to set up the network include logging into the router, changing the administrative password, modifying default DHCP IPv4 settings, and confirming connectivity.
- After changing settings, verify that devices can connect using the updated credentials and IP configuration.
Practical Applications
- Engage in hands-on activities via Packet Tracer to explore and implement wireless technologies in diverse scenarios such as office environments and areas with connectivity issues.
- Understand the role of wireless routers in small offices and home networks, which often combine switching capabilities with wireless access points.
- Familiarize yourself with the DHCP function in routers that automatically assigns IP addresses to connected devices.
