T440P network adapter not working with 5Ghz wifi - can I replace card ?

2019-07-10, 16:52 PM

Seems the Realtek 2x2 11bgn Wirelss **bleep** M2 Adapter that came with the T440P cannot work with 5Ghz ? 

I have seen articles claiming that the card cannot be replaced and others suggesting it can (but only if on a Whitelist ?). 

 

Anybody know the answer to this? And assuming I can change the card, any recommendations ? 

 

 

Solved! See the solution

You probably have a bgn card.  You need one that has "a" to do 5 gHz.  Here is the parts list for that model.  You want one with a matching FRU.

Thanks Rich,

 

Some vendors post a warning -

 

Important Notice: Please must check and confirm your computer's motherboard whether open USB bus before purchase, because this card is going Bluetooth USB bus, if the motherboard does not open the USB bus, then it's unable to use Bluetooth function, also in the device manager cannot identify the new USB Bluetooth hardware

 

I have never opend my T440 - do you know if this is something I need to be concerned with before ordering ?

 

Thanks again.

The bluetooth isn't a problem.  As I said, you need one of the FRUs on the list
