Helios 300 (PH315-52) - Terrible Wifi + Bluetooth interference?

First of all, I do realize that bluetooth & 2.4 GHz wifi networks interference is a thing - but I have never experienced anything remotely like this in any other device.
The super slow wifi speeds on my new Helios 300 were driving me insane.
After testing:
The following speedtests were performed in sequence - the only difference is that I turned on bluetooth and connected to my Google Home speaker for the second test:
Bluetooth off:

Bluetooth on, connected to bluetooth speaker:

I can consistently replicate these Speedtest results by toggling bluetooth on/off.
It does not seem to be specific to any bluetooth device - I see similar figures with the Google Home Speaker, with multiple BT headphones, and even my MX Master mouse slows down my wifi lmao
Currently it seems like I have to choose between fast wifi and using my bluetooth devices, which is ridiculous for a mid-range gaming laptop..
Any thoughts or potential solutions are welcome, thanks in advance.

After testing:
- multiple devices
- different wifi networks
- switching wifi channels on my router (1, 6, 11, etc)
- reinstalling bluetooth and wifi adapter drivers on my laptop
- changing just about every setting on the wireless network adapter
I found out that TURNING OFF bluetooth instantly improved my wifi speeds and browsing experience.

Anyone?
For reference: I did the exact same tests on an older Acer Aspire laptop, and the difference in speeds was much lower than in the Predator.

Just tested the speeds with my Dell work laptop:
without bluetooth: 35 down / 10 up
with bluetooth and music playing: 30 down / 10 up
So this really seems like this is specific to the Predator..
I reinstalled all the drivers last night, directly from Intel's website, but the problem remains.
The wireless adapter is a Killer AC 1550i. I also opened a support ticket with Intel to see if they can figure out what's going on..
This is incredibly annoying.. any experts wanna chime in please?

Killer's support told me to open a ticket with Intel support, and Intel's support is telling me to contact Acer support. Great!
I don't even know what this snippet is supposed to mean:Intel recently got this product, therefore we are not providing support for it.
The computer manufacturer is the one who is providing the support.0
