“What Can Go Wrong…”
1. Many APs create a lot of noise
2. Some APs can manage over the wireless out of box but should only manage
through hardwired connection; DO NOT connect wirelessly to manage the router!
3. SSIDs are the same on all Linksys; we want to change in the beginning of the lab
4. All routers use the 192.168.1.1 address; reassign IP address based on what
given by speaker
**After changing SSID and IP, disconnect and reconnect to router
5. As long as SSIDs are changed, overlapping DHCP scope should not be a
problem
6. Some Windows desktops loose their network connections and/or SSID broadcast;
this is a Windows issue
7. WUSB clients CD out of the box does not work with VISTA; CD setups do not
work with Macintosh
8. Internet Explorer should be used for all the management

Lab 7.2.5 Configuring a Wireless Access Point

Lab 7.2.5 Configuring a Wireless Access Point
Objective
•Configure the wireless access point (AP) portion of a multi-function device to allow access to a wireless client.
Background / Preparation
The Linksys WRT300N includes an integrated 4-port switch, a router and a wireless Access Point (AP). In this lab, you will configure the AP component of the multi-function device to allow access for wireless clients. The basic wireless capabilities of the multi-function device will be configured but this will not be a secure wireless network. Setting up a secure wireless network will be covered in a later lab.
The following resources are required:
• Windows XP based computer that is cabled to the multi-function device
• Linksys WRT300N
Step 1: Verify connectivity between the computer and the multi-function device
a. The computer used to configure the AP should be attached to one of the multi-function device’s switch ports.
b. On the computer, click the Start button and select Run. Type cmd and click OK or press Enter.
c. At the command prompt, ping the multi-function device using the default IP address 192.168.1.1 or the IP that has been configured on the multi-function device’s port. Do not proceed until the ping succeeds.
d. Write down the command used to ping the multi-function device.
The answer : ping 192.168.1.1 -t
NOTE: If the ping is not successful, try these troubleshooting steps:
• Check to make sure the IP address of the computer is on the 192.168.1.0 network. The computer must be on the same network as the multi-function device to be able to ping it. The DHCP service ofthe multi-function device is enabled by default. If the computer is configured as a DHCP client itshould have a valid IP address and subnet mask. If the computer has a static IP address, it must be in on the 192.168.1.0 network and the subnet mask must be 255.255.255.0.
• Make sure the cable is a known-good straight-through cable. Test to verify.
• Verify that the link light for the port where the computer is attached is lit.
• Check whether the multi-function device has power.
If none of these steps correct the problem, check with your instructor.
Step 2: Log in to the multi-function device and configure the wireless network
a. Open a web browser. In the address line, type http://ip_address, where ip_address is the IP address
of the wireless router (default is 192.168.1.1). At the prompt, leave the user name textbox empty, but
type the password assigned to the router. The default password is admin. Click OK.
b. In the main menu, click on the Wireless option.
c. In the Basic Wireless Settings window, the Network Mode shows mixed by default, because the AP supports 802.11b, g, and n wireless devices. You can use any of these standards to connect to the AP. If the wireless portion of the multi-   function device is NOT being used, the network mode would be set to Disabled. Leave the default of Mixed selected.
d. Delete the default SSID (linksys) in the Network Name (SSID) textbox. Enter a new SSID using your last name or           name chosen by your instructor. SSIDs are case-sensitive.
e. Write down the exact SSID name that you are using. __________________________________
____________________________________________________________________________
f. Click on the Radio Band drop-down menu and write down the two options.
____________________________________________________________________________
g. For a wireless network that can use 802.11b, g, or n client devices, the default is Auto. Auto allows
the Wide Channel option to be chosen and gives the best performance. The Standard Channel
option is used if the wireless client devices are 802.11b or g, or both b and g. The Wide Channel
option is used if only 802.11n client devices are being used. Leave the default of Auto selected.
h. SSID Broadcast is set to enabled by default, which enables the AP to periodically send out the SSID
using the wireless antenna. Any wireless devices in the area can detect this broadcast. This is how
clients detect nearby wireless networks.
i. Click on the Save Settings button. When the settings have been successfully saved, click on
Continue.
j. The AP is now configured for a wireless network with the name (SSID) that you gave it. It is important
to write down this information before starting the next lab or attaching any wireless NICs to the
wireless network.
