Replacing the Realtek wifi card with an Intel one

Hey everyone,

 

I am trying to replace the poor performing realtek wifi module with an Intel Centrino one on my T420.

 

I purchased an "Intel Centrino Advanced-N 6205"  which is one of the chips the T420 comes with.

Apparently my chip is not whitelisted, as I could not boot with it plugged in.

 

Lenovo support was unable to tell me where to get a Lenovo branded chip.

 

Can anyone help me out?

 

Thanks in advance!

Re: Replacing the Realtek wifi card with an Intel one

Hello and welcome,

 

As you've discovered, wifi cards have to be the correct model (Intel xyz) and have a Lenovo FRU number.

 

I can't link to the T420 Hardware Maintenance Manual at the moment - support is undergoing maintenance Smiley Sad

 

Here are the Intel models and FRUs from my local T420 HMM:

 

Wireless-N 1000                       60Y3241

Advanced-N 6205 (2x2 AGN)             60Y3253

Ultimate-N 6300                       60Y3233

Advanced-N + WiMAX 6250, WW SKU       60Y3195

Advanced-N + WiMAX 6250, Russia SKU   60Y3209

 

Hopefully that helps your search.

 

Z.

Hey,

 

thanks for the quick response!

Googeling for the FRUs did yield some promising results.

I just ordered one and hope that it works with my laptop!
