T400 unable to re-install WiFi driver

[jorthul]

Hi,

I am cleaning and re-installing Windows XP on several laptops.

I have an issue with 2 T400 laptops when trying to re-install WiFi driver.

First, I used the same procedure on several Lenovo laptops (T61, T61p) and I didn't encounter any issue.

The drivers I have downloaded are from Lenovo Website, using the full product identification.

Before cleaning and re-installation, WiFi was working well.

Here is how I proceed:

- install Windows XP Pro SP2

- install SP3

- install Ethernet driver

- install WiFi driver

and there comes the issue. The installation goes OK but the WiFi connection is not present in the Network Connections window. The little light with the WiFi symbol is not light up.

The manual switch on the front of the laptop is on (and the Bluetooth light is on).

I tried Fn-F5 but no change.

I tried to install Power Management, then WiFi driver, still not working.

I tried the pruduct detection but it gave me the same driver.

The file I downloaded is 7ywc54ww.exe.

Do you have an idea on how I could do to solve that?

Thank you.

Do the WLAN cards show up in Device Manager? Did you install the right driver? T400 came with Intel WLAN or ThinkPad WLAN card. Also are you 100% sure they are working? Try a Linux live disc and see if it connects in Linux.

Hmmm, seems to be 5 wireless drivers for the T400.

Yours is this one >>> Wireless LAN ThinkPad (11bg, 11abg, 11abgn) for Windows XP, 2000 - ThinkPad

Try the other 4.

You'll also need the hotkey package to get Fn+F5 to work.

Hi,

Thank you for your responses.

First I tried to install the hotkey fetures. then re-install the driver I had => no change

Then I tried to install this one:

Intel Wireless LAN (abgn, abg, bg) for Windows XP - ThinkPad >> http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/6mwc24ww.exe

and it worked.

Again thank you.
