WLAN Configuration

WLAN Configuration

1. Remote Site WLAN Configuration

   • The Wireless Router
     • typically include a switch for wired clients, a port for an internet connection (sometimes labeled “WAN”), and wireless components for wireless client access
   • Log in to the Wireless Router
   • Basic Network Setup
     • -Log in to the router from a web browser. -Change the default administrative password. -Log in with the new administrative password. -Change the default DHCP IPv4 addresses. Renew the IP address. -Log in to the router with the new IP address.
   • Configure a Wireless Mesh Network
   • NAT for IPv4
   • Quality of Service
   • Port Forwarding
     • Port forwarding is a rule-based method of directing traffic between devices on separate networks.
   • Basic Wireless Setup
     • -View the WLAN defaults. -Change the network mode. -Configure the SSID. -Configure the channel. -Configure the security mode. -Configure the passphrase.

2. Configure a Basic WLAN on the WLC

   • WLC Topology
   • Log in to the WLC
   • VIew AP Information
   • Advanced Settings
   • Configure WLAN
     • -Create the WLAN -Apply and Enable the WLAN - Select the Interface -Secure the WLAN -Verify the WLAN is Operational Monitor the WLAN -View Wireless Client Information

3. Configure a WPA2 Enterprise WLAN on the WLC

   • SNMP and RADIUS
   • Configure SNMP Server Information
     • Click MANAGEMENT Click SNMP Click Trap Receivers Click New...
   • Configure RADIUS Server Information
     • Click SECURITY Click RADIUS Click Authentication Click New...
   • Topology with VLAN 5 Addressing
     • Each WLAN configured on the WLC needs its own virtual interface.
     • The WLC has five physical ports for data traffic.
   • Configure a New Interface
     • 1.- Create a new interface. 2.- Configure the VLAN name and ID. 3.- Configure the port and interface address. 4.- Configure the DHCP server address. 5.- Apply and Confirm. 6.- Verify Interfaces.
   • Configure a DHCP Scope
     • 1.- Create a new DHCP scope. 2.- Name the DHCP scope. 3.- Verify the new DHCP scope. 4.- Configure and enable the new DHCP scope. 5.- Verify the enable DHCP scope
   • Configure a WPA2 Enterprise WLAN

4. Troubleshooting Approaches

   • Troubleshooting Approaches
     • 1.- Identify the problem
     • 2.- Establish a Theory of Probable Causes
     • 3.- Test the Theory to Determine Cause
     • 4.- Establish a Plan of Action to Resolve the Problem and Implement the Solution
     • 5.- Verify Full System Functionality and Implement Preventive Measures
     • 6.- Document Findings, Actions, and Outcomes
   • Wireless Client Not Connecting
   • Troubleshooting When the Network is Slow
     • 1.- Upgrade your wireless clients 2.- Split the traffic
   • Updating Firmware
     • Most wireless routers and APs offer upgradable firmware. Firmware releases may contain fixes for common problems reported by customers as well as security vulnerabilities.
