Problems with Intel BE200 WiFi Card

Hello,
I have just installed an Intel BE200 WiFi card in my HP laptop, since the original card did not support Linux.
Now, at least, there is connectivity.
However, things don't work well.
My internet speed is slow (127Mbps, while on my mobile phone, I am able to get twice as much).
And now Bluetooth is not working with all my headphones and speakers (I've tried several).
It seems something is related to the drivers.
But Intel only supports drivers for Linux Kernel 6.16.
Any suggestions?
Thanks!

This card should be supported from kernel 6.5 on. Maybe you need to install the firmware.

In this Case, You could install a newer Kernel. Instructions are here:

Try resetting your router completely via the router's settings (using a browser interface). Might also help if you told us what your router name and model are.
