very slow wifi when usb c devices connected

So yesterday I was thinking of calling my ISP and ask them to check on the connection because it was very slow.

But also, just to make sure it was there fault I ran a few tests on the router position and all.

I turns out I found a bigger problem, but on my MacBook Pro! Yes, that's right.

So I started by unplugging everything from my laptop and run an internet speedtest.

At first i moved close to the router and the speed was fine.

The I moved further away from where I was before and the loss was minimal. What the…

Then I started digging into this and connected every usb c dongle I had connected before and bam, connection speed dropped 90%.

So I did some more tests and changed the dongle from left to the right side of the laptop, and it improved a bit, still slow dought. But now it covered my audio jack.

So… Apple, this is not good for a veeeery expensive machine.

I'm now gonna run this tests with different machines and see what goes.

Not cool, at all.
