X250 - WWAN module

2018-02-12, 12:50 PM

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

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.

i purchased a second hand thinkpad x250 and after purchasing SIM card from my service provider and insert in the SIM slot, i wondered why my thinkpad was not working. however, after googling i discovered there was no Wireless WAN card in the slot. to my surprise there are also no antennas  line to be hooked to the WWAN card port. two antennas are only available for the WLAN ports. i may find the WWAN card from stores but i don't think i could not find the antennas. so, my question is does thinkpad x250 need antennas for the WWAN card or antennas are optional?does WWAN card work with out antennas connected?any help?

Module will work without antennas, but you may have limited or no reception. Installation of antennas is rather complicated, as they should be installed in the LCD assembly.
