WLAN Configuration by Mind Map: WLAN Configuration

1. Remote Site WLAN Configuration

1.1. The Wireless Router

1.1.1. Remote workers, small branch offices, and home networks often use a small office and home router Cisco Meraki MX64W

1.2. Log in to the Wireless Router

1.2.1. Most wireless routers are ready for service out of the box. They are preconfigured to be connected to the network and provide services.

1.3. Basic Network Setup

1.3.1. Log in to the router from a web browser After logging in, a GUI opens

1.3.2. Change the default administrative password. To change the default login password, find the administration portion of the router’s GUI

1.3.3. Log in with the new administrative password. the wireless router will request authorization again.

1.3.4. Change the default DHCP IPv4 addresses Change the default router IPv4 address

1.3.5. Renew the IP address. you will temporarily lose access to the wireless router.

1.3.6. Log in to the router with the new IP address. Enter the router’s new IP address to regain access to the router configuration GUI

1.4. Basic Wireless Setup

1.4.1. View the WLAN defaults.

1.4.2. Change the network mode.

1.4.3. Configure the SSID.

1.4.4. Configure the channel.

1.4.5. Configure the security mode.

1.4.6. Configure the passphrase.

1.5. Configure a Wireless Mesh Network

1.5.1. In a small office or home network, one wireless router may suffice to provide wireless access to all the clients

1.6. NAT for IPv4

1.6.1. find the IPv4 addressing information that the router uses to send data to the internet

1.7. Quality of Service

1.7.1. Many wireless routers have an option for configuring Quality of Service (QoS)

1.8. Port Forwarding

1.8.1. Wireless routers typically block TCP and UDP ports to prevent unauthorized access in and out of a LAN.

2. Configure a Basic WLAN on the WLC

2.1. WLC Topology

2.1.1. Topology

2.1.2. Addressing Table

2.2. Log in to the WLC

2.2.1. Configuring a wireless LAN controller (WLC) is not that much different from configuring a wireless router.

2.2.2. Network Summary

2.3. View AP Information

2.3.1. Access Points

2.3.2. This AP in the topology is a Cisco Aironet 1815i which means you can use the command-line and a limited set of familiar IOS commands

2.4. Advanced Settings

2.4.1. Most WLC will come with some basic settings and menus that users can quickly access to implement a variety of common configurations

2.5. Configure a WLAN

2.5.1. Wireless LAN Controllers have ports and interfaces. Ports are the sockets for the physical connections to the wired network.

3. Configure a WPA2 Enterprise WLAN on the WLC

3.1. SNMP and RADIUS

3.1.1. Topology

3.2. Configure SNMP Server Information


3.2.2. SNMP

3.2.3. Trap Receivers

3.3. Configure RADIUS Server Information


3.3.2. RADIUS

3.3.3. Authentication.

3.4. Topology with VLAN 5 Addressing

3.4.1. Each WLAN configured on the WLC needs its own virtual interface.

3.5. Configure a New Interface

3.5.1. Create a new interface.

3.5.2. Configure the VLAN name and ID.

3.5.3. Configure the port and interface address.

3.5.4. Configure the DHCP server address.

3.5.5. Apply and Confirm.

3.5.6. Verify Interfaces.

3.6. Configure a DHCP Scope

3.6.1. Create a new DHCP scope

3.6.2. Name the DHCP scope.

3.6.3. Verify the new DHCP scope.

3.6.4. Configure and enable the new DHCP scope.

3.6.5. Verify the enable DHCP scope

3.7. Configure a WPA2 Enterprise WLAN

3.7.1. Create a new WLAN

3.7.2. Configure the WLAN name and SSID.

3.7.3. Enable the WLAN for VLAN 5.

3.7.4. Verify AES and 802.1X defaults.

3.7.5. Configure WLAN security to use the RADIUS server.

3.7.6. Verify the new WLAN is available

4. Troubleshoot WLAN Issues

4.1. Troubleshooting Approaches

4.1.1. Identify the Problem

4.1.2. Establish a Theory of Probable Causes

4.1.3. Test the Theory to Determine Cause

4.1.4. Establish a Plan of Action to Resolve the Problem and Implement the Solution

4.1.5. Verify Full System Functionality and Implement Preventive Measures

4.1.6. Document Findings, Actions, and Outcomes

4.2. Wireless Client Not Connecting

4.2.1. Confirm the network configuration on the PC using the ipconfig command

4.2.2. Confirm that the device can connect to the wired network

4.2.3. Check the channel settings on the wireless client

4.2.4. Check for the presence of other devices in the area that may be interfering with the 2.4 GHz band

4.3. Troubleshooting When the Network Is Slow

4.3.1. Upgrade your wireless clients

4.3.2. Split the traffic

4.4. Updating Firmware

4.4.1. Most wireless routers and APs offer upgradable firmware. On a WLC, there will most likely be the ability to upgrade the firmware on all APs that the WLC controls.
