Got this 6th Gen X1 Carbon for 1 week, it's good in design, typical Thinkpad as usual, but the wifi speed does annoy me. Very slow on everything you need to do with internet. I regarded as my wifi problem, then I figured out it's the laptop itself. Did some google, bunch of similar complains overthere without any solution from Lenovo. So still dont kown what the problem is and how to solve it. It's quite shocked to get a new laptop with this stupid problem in 2019!! Considering to return this item. Please do some research on the wifi issue for this one before you buy it.
