2018 Mac Mini bluetooth and Wi-Fi interference

This week moved from late 2012 Mac Mini to a new 2018 Mac Mini. Same physical location, network, Apple bluetooth keyboard, Apple bluetooth mouse between the old and new Macs. In short, bluetooth connections to keyboard and mouse drop constantly when using wifi on new Mac (and after a few minutes Wi-Fi connection stops working completely). When connected via ethernet everything works fine. Hardware or software defect bug? Mojave 10.14.1.

Thank you!

For me it turned out to mostly be an external HDD. I can't have it anywhere near the Mac. I still lose bluetooth connectivity far more than I ever did with the old Mac Mini, so there's still an issue. I might try upgrading my Wi-Fi network to 5Ghz from the current 2.4Ghz.

Ultimately, it is a Mac Mini 2018 problem. Does your windows computer require that the 2.4GHz band be disabled? Other devices?

surely there are cables out there with suitable shielding and grounding?
