WiFi connection issues, redux...
Hi AppleHater,
Yes, I've experienced WiFi connection issues on three 2018 MBPs. The following link describes the problems I've had on the first two 2018 MBPs:

On the third 2018 MBP (just received it a couple days ago, so I'm still testing it), I've had WiFi connection issues causing the macOS 10.14.1 update to fail ... [In particular, while the update was not downloading, I started a ping of
www.apple.com and found 28% lost packets on the 2018 MBP. At the same time (simultaneously), I started a ping of
www.apple.com on a 2016 MBP attached to the same WiFi router, and found 0% lost packets -- so the WiFi issue was specific to the 2018 MBP.]
The third 2018 MBP also failed to receive an AirDrop of a 28GB Folder of files (it only transferred 4.5GB and then stopped/failed), but when I restarted the AirDrop the second time it completed the transfer. (AirDrop uses Bluetooth to establish a private P2P WiFi connection, so for the first AirDrop attempt the WiFi had problems, but then an immediate subsequent AirDrop worked properly without any WiFi issues.)
The third 2018 MBP also failed to unlock with my Apple Watch, claiming the signal was too weak, but I immediately then attempted to unlock the 2016 MBP and an iMac with the Apple Watch, and both unlocked normally. All three machines are on the same desk, so only the 2018 MBP failed while the other two were successfully unlocked. (I believe the Apple Watch unlocks the Macs via WiFi, so this is probably also a WiFi connection issue.)
I've use the 5GHz band 802.11ac and have tried several different WiFi routers...all have had the same WiFi connectivity issues on the 2018 MBPs. (Intriguingly, when the WiFi connectivity has problems, the WiFi hardware is still operating, i.e., WiFi packets are still being sent/received by the 2018 MBP during the time that Safari/Mac App Store/rsync/ssh/ping are not working.)
In summary, in my hands, I've had three 2018 MBPs that have had rare, random, and often intermittent WiFi connection issues. (By "intermittent" I mean that these WiFi connection issues will often resolve themselves, often within a minute or two, but I have waited 150 minutes without the WiFi connection being re-established and I had to manually fix the WiFi connection. By "rare" and "random" I mean that these WiFi connectivity issues happen rarely and at any time -- I haven't been able to figure out how to cause them with impunity, they just happen. And because these WiFi issues are intermittent I'm sure that I don't catch but a small fraction of them.)
Hope this helps. If you wish, you might read the post in the link above for further details.
