T400 unable to re-install WiFi driver

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.

Re: T400 unable to re-install WiFi driver

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.

ThinkPad Z61t - T7200|3 GB|GMA 950|640 GB MomentusLP|WXGA|XP Pro X 2 (2nd one has 750 GB Scorpio Black)
ThinkPad T60 - T2400|3 GB|GMA 950|500 GB Scorpio Black|SXGA+|XP Pro
