Which WWAN card do I need in a 3rd gen carbon x1?

2016-05-17, 21:10 PM

I bought a Sierra EM7355 card for my 3rd gen Thinkpad x1 - according to http://www.thinkwiki.org/wiki/Category:X1_Carbon_(3rd_Gen)


but it doesn't work when I plug it in (won't boot up). Which card do I need? Is it the EM7345?

Solved! See the solution

Hello, genealogyxie

You are right, only Sierra em7345 (LTE/3g) and Ericsson n5321 (3g) wwan modems are compatible with x1c gen3. Note, they must have Lenovo FRU p/n, 04X6014 and 04W3842, respectively.

em7355 (Gobi 5000) isn't in the compatibility list.

Do it well, worse becomes itself
