How we confirm that my T41 has the which wireless radio card? because When I install both "Intel (R) PRO/Wireless LAN 2100 3B Mini PCI Adapter" or
Both works , but the problem is same with using TP-LINK (TL-WA501G) Access Point,
that wireless radio on and off after few seconds repeatedly.
My other Dell laptop works without any problem , but other way round my T41 is connecting and after few seconds disconnects.

Assuming that the website is working properly today (seems to have been having problems lately), you can do a parts lookup of your system with it's serial number and model here...
That's assuming that no one has changed any of the hardware of course.
You can also try connecting with ethernet and uninstall the drivers then run system update. Hopefully it will identify and install only the correct driver.

Since many T40 and T41's came with "wireless upgradable" a lot of them got a wireless card attached later.
In the device manager double-click the wireless lan device and select the "Details" tab.
under "Device instance ID" you will find an entry like "PCI\VEN_xxxx&DEV_yyyy..."
Input the digits under "yyyy" in the upper right input field on www.pcidatabase.com
The serach result shows all devices with that Device-ID. Compare your Vendor-ID ("xxxx") with the vendor - ID in the result list.
