My wireless device is an Intel Corporation Wireless 8265 / 8275. Although my bluetooth is working fine, it looks like whenever I'm using a bluetooth device the internet connection is even worse. I'm using an ASUS laptop, the drivers and BIOS were updated recently (less than a year ago).
In the last few days, my internet connection has been painfully slow and unstable. At first, I thought it was a problem with the provider, however, when using Windows on another computer the internet is working perfectly fine. I could not find any solution for this problem and I do have reasons to believe I'm not the only one experiencing this issue.

I have already tried disabling 802.11n, disabling IPv6 support, and also the power save options. Nothing seems to work.
Any suggestions?
Thanks.
