What is the exact specs of that WiFi module, is it MIMO 2x2 or 3x3? Is it the same module what we can found in the Mac with 4 and 2 TB ports? Wikipedia says “Built-in Wi-Fi 5 (802.11a/b/g/n/ac), up to 867 Mbit/s (13" Two Thunderbolt 3 ports) or 1.3 Gbit/s (13" Four Thunderbolt 3 ports and 15")”. This would mean MIMO 2x2 for the 2 port ones and 3x3 for the 4 port ones. I hope this is a Wikipedia typo as my old late 2013 MBP has 3x3 MIMO… it would be weird if Apple would have been degraded the Wi-Fi performance since 2013… Actually not sure why Wi-Fi specs not part of the official Apple tech specs.
You’ll need to talk with Apple to get their story on why the two port model only offers a 2x2 MIMO configuration Vs the four port model which has a 3x3 MIMO antenna setup.
Two antenna connections - 2019 Two TB Port system
Three antenna connections - 2018/19 Four TB port system
