Context: this is a legit screenshot I took on my workplace around 1.5 years ago. Hopefully it's been patched by now? Completely ridiculous behavior

Badly shielded USB3 causes RF leaks at 2.4GHz. use 5Ghz WiFi or better shielded devices.
This is the answer.
Some early wifi routers with USB ports on them had the same issue.
I’ve seen this exact problem on other laptops. Not saying it’s okay, but it’s not exactly an Apple only problem. It’s a “let’s cram everything into this single port and hope it doesn’t interfere with anything” problem.
It’s also a common problem with 2.4 GHz Zigbee USB sticks. It’s recommended to connect them to a longer usb cable.
Add the Logitech unifying receiver to this list. It cuts out constantly with the dock model most people use at my work, and I have to put it on a dongle or extension cable to fix it.
That’s an interesting one….
Better laptops tend to put the wifi antenna in the display, so it's far away from the USB ports when in use. Obviously that's not compatible with ultra thin laptops.
All laptops have their wireless antennas in the lid of the laptops. MacBooks included.
The amount of RF generated by some devices is insane.
But if the antenna passes the usb port then it doesn’t really matter.
A friend of mine had a $2500 gaming laptop that couldn’t use WiFi when he used an external display. He ended up having to use two separate dongles, one for DisplayPort and another for Ethernet. It worked, but was pretty dumb. In the end, though, I was happy that at least he was using a wired connection.
Ideally it passes by shielded. Or better yet, shield both.

Charging from the left side isn't all that either, some macbook pro models actually become slower due to thermal throttling because charging from the left creates heat closer to the CPU. Resulting in a significant CPU slowdown.
What an amazing screwup
