Hey there. I just formated my IBM t40 and after I run all the up-dates including service pack 2 I try to connect to my romemates wireless connection (secured connection). The problem is, that it tries to connect without asking for the network key, and it failes to connect. An error message appears saying, that "Windows is unable to connect to the selected network. The network may no longer be in range. Please refresh the list of available networks, and try to connect again." I have tried everything I can imagine also in the properties of the wireless network and have no idears left. Before formating the computer I had no problems connecting to the network. Do you maybe have any idea of the problem?
1) If you are using the Windows Default Wireless Network Connection. Open the windows where you you will see a list of all wi-fi connections near by your location. On the left panel(Related Tasks) click on "Change Advance Settings" >> Wireless Network Connection Properties >> Click "Wireless Network" Tab >> from the Preferred Networks: list, remove the wi-fi connection you are trying to connect. Once your W-Fi connection settings are removed. You can either add it manually clicking on the Add button and entering all informaiton manually, or from the wi-fi network list click the network name it will ask you to enter the netowkr key....
2) if you are using any other Wi-Fi connection application, like the Intel's, follow the same procedure. delete the settings and try connecting again.

Hello, if you see a yellow exclamation mark it means device drivers are not installed or are incorrect.
below is the link for IBM/Lenovo site that lists all the drivers for Thinkpad T40/T41. Go to that linkand scroll down to " Wireless Networking" and select the appropriate drivers: eg: Make sure it under T40 section, and not T41 since they are listed side by side.
since i am not sure which exact wireless card your T40 has i am posting this main link where it lists all options.
I would start with "ThinkPad 802.11bg wireless LAN Mini PCI adapter" if this doesn't work try next one in the list.
here is the link: http://www-307.ibm.com/pc/support/site.wss/MIGR-46258.html#wireless
I hope this helps, let me know if there is a problem.
First we need to remove the previous profile in your wireless network. I believe you know the SSID for wireless connection using WEP security. You can check this by going to;
Using Windows XP SP2/3 1. "Control Panel" > Switch control panel to classic view ( look at the upper left side ). > Double click "Network Connections" > Right click "Wireless Network Connections" > choose "Properties"> Click the Tab "Wireless Networks" ( middle tab) > go to the list of profiles and remove the Wireless name or SSID for your home connections. > click OK and Close the properties of wireless.
To reconnect again, you need to know your WEP key or network key for wireless connections if not, you can do this procedure...
1.Connect the computer to one of the four LAN ports (i.e port 1, 2, 3 or 4) on the back of the router. The corresponding port light where you connected the computer should be lit up.
2. Access the router's web-based utility.
a. Please open any web browser like Internet Explorer or Netscape Navigator. b. Connect to the router by typing http://routerlogin.com/basicsetting.htm or http://192.168.1.1 in the address field and click Enter or Return key. c. A window will prompt for a user name and password. By default, the user name is "admin" and the password is "password". d. Click on the Wireless Settings under Setup. e. take note of the KEY 1 ...that is your WEP key..take note of it.
