When I purchased this MacBook Pro, right out of the box I was experiencing dropped WiFi connections. Now I thought this was a simple bug and could be fixed by restarting/resetting SMC or PRAM reset, however, that wasn't the case. I'm still experiencing dropped WiFi connections even after doing those resets AND updating to 10.15.4.
Not sure why this keeps happening. Am I the only one?

Maybe your new MacBook Pro is generating some amazing USB 3 interfrence from its peripherals:
Why do I have difficulty with Wi-Fi or Bluetooth devices when USB 3 devices are attached to my computer?
Some USB 3 devices can generate radio frequency interference that can cause Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer. Here are some tips to avoid this issue:
• If your USB device has a cable long enough that you can move the device, place it away from your Mac—and make sure not to place it behind your Mac, or near the hinge of its display. The antennas for Wi-Fi and Bluetooth are located there, and USB 3 devices placed there might interfere with your wireless connections.
• If you're using adapters or dongles on a Mac computer with Thunderbolt 3 (USB-C) ports, plug them into the front port on the left side of your Mac, or into the ports on the right side (if your computer has them). These ports are the farthest away from the antennas, making interference less likely.
• To avoid interference on the 2.4GHz band using Wi-Fi, try using the 5GHz band instead. You can change this on your wireless base station. Bluetooth always uses 2.4GHz, so this alternative isn't available for Bluetooth.
--from an older Apple article, now retired.
as of this writing that 10.15.6 supplemental update still has a Beta software, developers-only designation.
I don't have apple watch. So I'm waiting 10.15.6 ....
You don’t need to have a watch for toggling this setting .... the watch itself has nothing to do with this problem.
Same issue with my MacBook Pro 16, 2019... Every time after I reboot my MBP, the wifi will stop working after a while and I will have to manually disconnect and reconnect back the wifi.
At this writing, MacOS 10.15.7 has been released for everyone.
You should test that version to see if the issue has been solved or changed.
Readers would love to hear your results
10.15.7 has helped me, it's been much better
New MacBook Pro today. Can’t get the unlock with watch to turn on keeps saying can’t connect to the watch. Now restoring from a backup and will try again when this completes. Probably in a few days
Does anyone who experience wi-fi issues use(d) custom /etc/sysctl.conf in their systems? If yes, please share its content.
PS: in latest macos this file doesn't exist by default.
