Question about IBM ThinkPad T42 Notebook

1 Answer


My internal wireless if off, and Fun/F5 don`t work, how can turn my wireless on. Thanks


  • mmaddo Nov 04, 2008

    Hard Disc has been reformated. IBM drivers reinstalled. Wireless can be turned on/off from Microsoft XP and connects. The IBM software for controlling the wireless is installed, claims to be switching wireless on and off but itsn't (permenantly on). Tried ticking the box in XP to say a different system is controlling the wireless but still doesn't turn it on/off. I suspect a missing dll or component. Any ideas?

If there is an icon in the taskbar refereing to your wireless connection, right click it then properties, then connect. You can also get to it through control panel> internet conenctions and then click on your wireless connection and click enable.

My wireless was working on my T42 IBM last week. It is not working now. The only thing that happened in between is that I installed Microsoft Office. How can I get my wireless back? I get a message that I...

For most IBM ThinkPads, the shortcut key to activate wireless is Fn+F5. I am not so sure about this model, but you can try. If this doesn't help, check the Device Manager and make sure it's shown on the devices lists. By default wireless is activated once the driver is installed on almost all IBM ThinkPads. You problem could be driver corrupted or missing. The best resolution is reinstalling the driver so that it'll not fail. If the problem persists, then it could also be your wireless card failure. You better check it twice.

Good luck.

Where is the 'Wireless Switch' on the IBM T42

The T42 has a bulit-in wireless network adapter and a LAN network card. T42s most likely have an Intel wireless card or less likely a Cisco wireless card.
Your wireless network adapter may have been disabled in the BIOS
The drivers for the wireless network controller has not been installed.

To check the network adapter go to the Control Panel, Click on System, click on Hardware Tab then Device Manager. Then scroll down and click on Network adapters. If you don't see your network controller or you see a yellow ? against Other devices for the Network controller. Then either it has been disabled and/or the driver was not installed.

To get the driver for the network controller you need to dowload it from the IBM/Lenovo WEB site their support/download page from a computer that has Internet access. Make sure you select your laptop model and the driver for your Windows version.
Install the driver and you then need to configure the wireless adapter to suit your wireless router settings before you can access the Internet.

This will help. Thanks please keep updated. please do rate the solution positively .Thank you for using Fixya

Where is the wireless button on t42 thinkpad

There's no hardware switch to activate and deactivate the wireless networking, but pressing Fn and F5 brings up a menu that allows you to turn Bluetooth on/off, WiFi on/off or both. It seems like IBM isn't satisfied with standard toggle buttons like other notebook manufacturers - even pressing the Fn and F7 buttons to switch between internal and external screens, brings up a menu with multiple display settings and resolutions.
Hope this helps,
