Wifi роутер cisco packet tracer

In this lab, we will configure WIFI in Cisco packet tracer and we will be enabling the laptop for wireless connection using a wireless router

Configuring a wireless router and creating a wireless network is easy in a packet tracer. It is almost the same as configuring the home wireless router.

There are varieties of wireless devices given in the packet tracer so we will select the wireless router WRT300N from the list.

Now, we have to configure the wireless router. Most of the settings are already configured on the wireless router required to establish a wireless network however, we can change the configuration as per our requirement and enable features like an access list, MAC address filtering, firewall, etc.

We can change the DHCP scope as per our requirements however in this lab but we will keep those settings to default.

SSID is configured as ‘default’ but we will change that to ‘packet’ and wireless security is disabled by default on the router so we will enable security and set up a password.

WPA2personal security mode has been selected and password packet123 has been configured on the router.

After configuring the router, we must save the setting. The save button is not visible on the screen until we scroll down.

Now, we will configure the laptops so they can join the wireless network.

By default, the laptop does not have a WPC300N module installed and there is no extra space to install the module so we have to remove the Ethernet module and replace it with a WPC300N module.

Before changing the module, the laptop must be powered off otherwise, the module cannot be changed.

If we will not change any setting on the router then changes are not required on the laptop as well because the laptop is preconfigured with the SSID and a password is not required so the laptop will establish the connection with the router just by installing the wireless module.

As we have changed the SSID and password on the router, we should configure the laptop with the required information.

The laptop will establish a connection when configured with the appropriate SSID and password. Now, we can open the GUI of the wireless router on the web browser of the laptop.

We have to enter the IP address of the server in the web browser and then the browser will ask for the username and password, which is admin for both. After the successful authentication, we will be able to configure the router on a laptop.

Лабораторная работа №5: Cisco Packet Tracer: Wi-Fi (10.05.2018)

Создать модель локальной сети, состоящей из обычного домашнего wi-fi роутера и маршрутизатора, который имитирует провайдера Интернета. Использовать интерфейс Fast Ethernet. Добавим ещё пользовательское устройство, например ноутбук. Установим модуль wi-fi (WPC300N) в ноутбук.

Настройка модели

1)Настройки маршрутизатора провайдера Router0 (жирным выделено то, что необходимо ввести с клавиатуры:

Router>en
Router#
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router (config)#int fa0/0
Router (config-if)#ip address 210.210.0.1 255.255.255.252
Router (config-if)#no shutdown

Router (config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

Router (config-if)#end
Router#
%SYS-5-CONFIG_I: Configured from console by console

Router#wr mem
Building configuration.
[OK]

2)Настройки домашнего wi-fi маршрутизатора Wireless Router0

выполняется с помощью веб интерфейса.

Настройка внешнего интерфейса во вкладке Setup показана на рисунке.

Настройка локальной сети (Network Setup)

Выбираем по умолчанию ip-адрес 192.168.0.1, маска 24-битная 255.255.255.0, разрешён DHCP-сервер, начало раздачи с адреса 192.168.0.100 и всё. После чего незабываем сохранить настройки, нажать на кнопку внизу формы Save Settings.

Настройки во вкладке Wireless, т.е. wi-fi. Выбираем основные настройки вайфая: режим (mode), мы выбираем смешанный (mixed); идентификатор сети (SSID) — netskills; ширина канала (Radio Band) — auto; частоту — 1-2.412HGz; видимость сети (SSID Broadcast) — видимая (enable). Сохраняем настройки.

Переходим ко вкладке Wireless Security. Выбираем режим шифрования WPA2 Personal, алгоритм шифрования AES, ключевое слово для выбранного режима шифрования не менее 8 символов. Сохраняем.

3)Настройка wi-fi адаптера на ноутбуке. Вкладка Desktop->PC Wireless->Connect. Смотрим доступные нам сети. Нажимаем кнопку Connect для подключения к сети netskills.

Если настройки произведены верно, то появиться пунктирная линия между wi-fi маршрутизатором и ноутбуком как на рисунке.

Введём на ноутбуке в командной строке команду ipconfig, чтобы проверить правильность настроек. Из рисунка видно, что DHCP- сервер присвоил правильный ip 192.168.0.100 Пропингуем шлюз (wi-fi маршрутизатор) и пропингуем адрес интернет провайдера. На рисунке видно, что в обоих случаях пинг идёт.

При этом NAT мы не использовали, так как практически на всех wi-fi маршрутизаторах NAT используется по умолчанию.

Packet Tracer 7.3 — WLC configuration

The Cisco Wireless Controller (WLC) devices is the Cisco solution to centrally configure, manage enterprise wireless networks, regardless of the number of access points deployed and thei location. Wireless controllers have become very popular as companies move from standalone Access Point (AP) wireless designs, complicated to configure and to secure properly, to centralized controller-based designs, reaping the enhanced visibility, functionality and redundancy benefits that come with those modern designs.

The following youtube video presents the basic concepts of how Wireless Controllers work and interact with Lightweight access points using CAPWAP protocol. A good understanding of the concepts presented in this video is mandatory before starting this Packet Tracer 7.3 wireless tutorial.

Tutorial introduction

This Packet Tracer 7.3 wireless tutorial will show you how to configure the Wireless LAN controller and the associated Lightweight Access Points embeded in Cisco Packet Tracer 7.3 including :

• WLC 2504 intial setup
• SSID and VLAN configuration on th WLC 2504
• Security configuration using 802.1x
• LightWeight Access Points 3702i automatic registration

This tutorial will be based on the following network topology :

Management IP addressing (Vlan 1 / 192.168.1.0/24)

• Cisco WLC 2504 : 192.168.1.254
• Catalyst L3 switch : 192.168.1.1 (vlan 1 default gateway / DHCP server)
• Management laptop : dynamic IP address from DHCP
• Lightweight Access Points : dynamic IP address from DHCP

Cisco WLC 2504 initial setup

Connect to the WLC 2504 using the web browser of the management laptop using http://192.168.1.254 and configure the admin username and password. The admin credentials will be login: admin, password : P@ssw0rd in this tutorial. Make sure to connect using HTTP (unsecure), not HTTPS, for this first connection.

Packet Tracer 7.1 issue : Access to the web interface can fail several times before allowing showing the following page. It works after a random number of tries.

The second step is to configure time, location, and management IP address of the WLC before creating the first protected Wireless network. Please note that the Guest Network function is not supported in Packet Tracer 7.3 .

After this initial setup, reconnect to the Cisco WLC using HTTPS (https://192.168.1.254). If you try to connect using HTTP (unsecure) the WLC resets the connection but doesn’t automatically redirect the connection to the HTTPS url.

SSID and VLAN configuration on the WLC

WLAN creation and SSID to VLAN mapping is configured on the WLAN tab of the WLC configuration. Each WLAN SSID is associated to a VLAN previously created and linked to a pysical interface on Controller tab. Packet Tracer 7.3 supports the following security options :

• No security
• WPA2 Personal
• WPA2 Enterprise (802.1x)
• Static WEP
• Static WEP + 802.1x
• CKIP
• None + EAP Passthrough

Security configuration using 802.1x

LightWeight Access Points automatic registration

Cisco Lightweight access points are directly connected to the layer 3 Catalyst 3560 switch and are PoE power supplied by the switch, making deployment quite easy. Attention is required for the access switch deployment which needs reduncdant power supplies and suffisant power budget from the closet to power up all the connected WLC.

Switch#show power inline Available:370.0(w) Used:15.0(w) Remaining:355.0(w) Interface Admin Oper Power Device Class Max (Watts) --------- ------ ---------- ------- ------------------- ----- ---- Fa0/1 auto on 5.0 Light Weight Access Point0n/a 15.4 Fa0/2 auto on 5.0 Light Weight Access Point1n/a 15.4 Fa0/3 auto on 5.0 Light Weight Access Point2n/a 15.4

Lightweight Access Points automatically discover the WLC address using DHCP option 150 configured on the DHCP which has been configured on the Catalyst switch for Vlan 1.

ip dhcp excluded-address 192.168.1.1 192.168.1.9 ! ip dhcp pool MGMT network 192.168.1.0 255.255.255.0 default-router 192.168.1.1 option 150 ip 192.168.1.254

The WLC displays thesuccessfully registered Access Points with thir IP address. detailed data is not available as this function has not been implemented in Packet Tracer 7.1

Known issues

When configuring the WLC port to trunk mode and applying a static IP to the WLC, connection to the management interface of the WLC fails. The issue has been identified by Cisco and it’s correction has been integrated in Packet Tracer 7.1.1

Packet Tracer crashes when configuring DHCP on WLC-PT wireless controller. Issue will be corrected in Packet Tracer 7.2
