For me, this "new" driver version (126.96.36.199) seems to be the reason for this problem. Since the automatic installation of this driver over windows updates the internet connection is lost after sleep every time. I have the windows 10 1903 installed.

I'm having a similar issues, X1 Carbon 6th Gen, except it never reconnects to the gateway. I have to switch WiFi connections, or turn the WiFi off and back on again to get it to connect. This problem occured AFTER one of the driver updates, maybe 1-2 months ago. It did not occur for the first 6 months I had my X1 Carbon.

Same here, I suddenly have had this problem for the last month or so... I need to swith WiFi off and back on...
Very frustrating to have something working and suddenly not...
I tried the Intel update but no luck there.
Can Lenovo please do smth about it ?

I rolled mine back. It looks like there have been about 6 updates since November 2018 (when I bought my X1 Carbon). I'll report when I have more data.

Also having issue on 188.8.131.52. Just started recently, presumably after an automatic update. I don't think the issue is that you can't connect to your default gateway -- i think it's not actually re-associating to the SSID and just showing the last previous network you were connected to as currently connected.
Can those that are having the issue confirm whether or not when your laptop resumes from standby and it shows that you're still connected to WiFi -- what happens if you take your laptop somewhere else? Does it still show connected to that same wifi when you resume? if I take my laptop to starbucks and resume from standby, it shows that i'm still connected to my home wifi. I have to power WiFi off and on, and then it will auto-reconnect to xfinitiwifi or Starbuck's wifi.

Installing the one from the Intel website (at least now) will get you 184.108.40.206, which is the one that does not sleep/wake properly.
220.127.116.11 absolutely works. You you select the device under "Device Manager" go to "Driver", then "Update Driver".
"Browse my Computer", then "Let me Pick". You will have a list of identical drivers. Pick the third one down. After loading, look at which one it selected. Keep trying until find it.

I did something a little different. I just rolled back the driver to the "previous" version, where Windows chose that version, namely 18.104.22.168. That has been working all day today, with a number of suspends and return from suspend.
