I can confirm I have the same issue.
Same setup as you, just finished installing the Fibocom card and during my first tests I ran into exactly the same issue as you: Win 10 bluescreens 100% when I run an internet speedtest via LTE. Last thing I can see is download speed running past 100Mbps, and then boom, bluescreen.
Latest updates, firmware, drivers, etc.
Speedtests on ethernet or wifi are no problem.
This is really not good.

I have excatlly same issue on my X1 Yoga Gen3, after upgrading RS5, October update 2018.
I already update to new driver v22.214.171.124, but still same problems...

Good to know I'm not the only one. So chances are this is not my particular unit/card being defective, and hopefully it's not a hard design issue, rather a driver/firmware issue that can be fixed by a later release. However, I would not bet on Lenovo fixing this super quickly. Some users on Reddit mentioned that it took Lenovo a year to release a working firmware on a previous model Sierra LTE modem. Yikes.
I do wonder if this is related to W10 1809. I wiped and clean installed right away upon receiving my laptop so I did not have a chance to do any tests while on 1803. Really don't have the time to go back and forth just to diagnose this issue.

By any chance you can be certain that prior to the RS5 upgrade, the laptop did not exibit this issue? If we can be sure that it's just a matter of 1809, I won't mind just installing 1803 and stay on it till the issue is fixed.

As you said in another post, you installed wwan card and antenna by yourself?
So did you properly plug the tunable antenna connector into the camera module?
Because for LTE, a single channel download/upload speed is limited, to achieve high speed download/upload, the wwan card must turn on Carrier Aggregation, which might need some operations on the antenna side. This might crash the OS if tunable antenna is not accessable.

I bought mine off ebay which comes with LTE already installed. I assumed it's from factory, as I thought it'd be unlikely for the seller to install this module. Is it possible to check for sure?
My machine type model is 20LES27P00. I just checked under my warranty -> Machine Info, the WWAN card appears to be unmentioned,

I ran some further tests today and interestingly, I couldn't reproduce the problem with Chrome browser. It crashes constantly with Edge browser, which is what I generally use on Laptops for better battery life, and on which I first noticed the problem.
Are those of you who're experencing the same issue happen to be using Edge? If so, can you try speedtest on Chrome?

me too. It dosen't depend on any kind of web browser. Edge, Chrome, Firefox, everything. It is caused by highly big date transfer.....
