IBM Thinkpad T40 Connecting Wirelessly using the built-it Wireless Adapter

IBM Thinkpad T40: Connecting Wirelessly using the built-in Wireless Adapter


This is a step-by-step example of how to use an IBM T40 portable's own wireless adapter to connect to your existing local wireless network. The general steps will work for other, similar situations, (such as not using WEP). The hardware and software used are.

  • Wireless Adapter - Cisco Systems PCI Wireless LAN Adapter (Driver v3.4.9.0)
  • IBM Thinkpad T40 laptop
  • Windows XP
  • IBM Access Connection software

The network that the computer will use is:
  • An existing 802.11 network using a NETGEAR wireless router
  • WEP security is used as an example, (however, you must match whatever security your local network uses.)

The step-by-step instructions create a wireless LAN connection to the wireless router or access point, allowing you to share network resources such as printers, files and folders. Internet connectivity is not guarranteed as it depends on a properly established connection to your Internet Service Provider (ISP).  Default settings were selected and used where appropriate to minimize time in creating a working connection.  Changes and modifications can be easily made after the connection profile has been established.

Although there are many steps to the procedure described below, each step typically only involves one or two selections.  This document also attempts to break the steps into logical sections to give the user a better sense of what is being accomplished at certain steps.

Create a new connection profile

1.  Verify that there is no wireless connection. The screenshot shows the wireless icons in the System Tray when there is no wireless connection.

A - The IBM Access Connection status. A red X means there is no wireless connection.

B - The Cisco Systems PCI Wireless LAN Adapter status.

If the no wireless connection condition exists, follow these instructions to use the IBM Access Connection utility to create a new connection.

2. Double-click IBM Access Connection (A).

3. Click Create

3. Enter a name for the new profile, for example My Home Network

4. Select Wireless 802.11 connection to an AccessPoint or Residential Gateway (WLAN)

5. Click Next

6. Verify that a wireless adapter is selected, in this example Cisco Systems PCI Wireless LAN Adapter.

7.  Click Next

Enter Basic Network Settings

8.  Leave the default settings for IP Address and DNS server, unless you know there are specific entries to be used for your network.

9.  Click Next

10.  Do not change the default settings for Advanced DNS settings, unless you know there are specific entries for your network.

11.  Click Next

Finding the Wireless Network Name (SSID)

12.  Click Find Network... or enter the SSID for your wireless network.

13.  Select your network name (SSID) from the list.

14.  Click OK

15.  Verify that the correct wireless name (SSID) is selected, in this example NETGEAR.

16.  Verify that Connection Type is set to Access Point

17.  Select Enabled - Use Static WEP Keys

18. Click Next

Entering Security Settings

19.  Select the security settings used by your local network, for example Enable - 128 bit

20.  Verify that Access Point authentication is set to Open.

21.  Select the correct Key sequence to use, in this example Key 1

22.  Select Use 26 Hexadecimal Digits

23.  Enter your manual key sequence.

24. Click Next

Optional Settings

25.  Click Next or enter Internet Explorer Proxy Settings.

26.  Click Next or select additional Security Settings.

27.  Click Next or select a printer to be used.

28.  Click Next or enter Program Setup.

Save and Apply the New Connection Profile

29.  Click Save.

30.  Click Yes.

The IBM Access Connection A now shows a connected status (with no red X). 

You now have wireless access to your local network. If your network is connected to the Internet, then the laptop also now has Internet access
