Hi and thanks for writing this. I have a x1 carbon gen7 and I have read all the threads on lenovo forum and reddit.
I wonder how I can tape the PCI-e to try your solution, do you know where to learn this ? I am thinking to get the same modem as you but if I can switch it to usb and do as you said it will be better because I don’t know what device will work with network in SEA. Could be nice to speak to you. Best and thanks for the blog. Dimitri
