ThinkPad T43 Won't Connect to Available Wireless

The IBM ThinkPad T43 is a laptop computer specially designed for business users and runs the Windows operating system. It also contains an internal wireless network card, which allows users to connect to local wireless networks without additional hardware. If you are having trouble connecting to available networks, you will need to troubleshoot your wireless adaptor and potentially update its driver.

Check the wireless radio button on the front of the IBM ThinkPad T43. If the radio button is in the "Off" position, wireless connections will not work until you switch the button to the "On" position.

Open the "Start" menu and click on "Control Panel."

Select "Network and Sharing Center" from the list of services.

Click on the "Change Adapter Settings" link in the left-hand column of the window.

Right-click on the icon for the IBM ThinkPad T43 wireless network card and choose "Properties."

Highlight "Internet Protocol Version 4 (TCP/IPv4)" from the list of connections and press "Properties."

Choose the radio buttons labelled "Obtain an IP Address Automatically" and "Obtain DNS Server Address Automatically." Then click "OK."

Go to the IBM ThinkPad T43 download page and download the latest wireless networking driver if connections are still failing. Once you have downloaded the driver and followed the on-screen instructions to install it, restart your laptop and try connecting to a wireless network again.
