X250 - WWAN module

Hello,

 

I have the Thinkpad X250 and would like to install the WWAN module.

Can you please advise the exact model?

I have tried the EM7455 but got the following error after power on: 1802 unauthorized network card is plugged in

 

Thank you in advance,

Noam

Re: X250 - WWAN module

EM7455 isn't a whitelisted WWAN module for your X250 - it was whitelisted for Skylake's ThinkPad generation devices. There are two dedicated WWAN modules for your device:

- FRU: 04W3842, Ericsson N5321 HSPA+ 21Mbps M.2 WWAN.

- FRU: 04X6014, Sierra EM7345 LTE/HSPA+ 42Mbps M.2 Card.

 

You must buy a module with correct FRU on label. There are generic modules available on the market, but they won't work with your X250, as BIOS will detect them as unauthorized devices.
