use intel wifi card without interruptions

[luk]

Hello,
I bought a new laptop and installed arch on it.
It has the following wifi adapter:
Intel Corporation Ice Lake-LP PCH CNVi WiFi
this is the pciid: 8086:34f0

My current situation is, that I use my phone for usb tethering,
because my wifi times out periodically in short intervals.

I don't know how to fix it. I'm on arch and troubleshooted a bit,
by disabling bluetooth coexistent.

I am using a bluetooth headset with my laptop.

I don't understand what is going wrong, but I think it must be something
with the card, because my android phone does a good job with usb tethering,
also while I am using the bluetooth headset.

Any hints?

I put this into my iwlifi.conf:
options iwlwifi 11n_disable=1 swcrypto=1 bt_coex_active=0

what disturbs me about this is, that I can still use my bluetooth headset.
Is this just ignored, or is the configuration not loaded?
I assumed rebooting is enough. I also checked the config with modprobe.

[lukas@medion windows_drivers]$ modprobe -c iwlwifi | grep bt_coex
options iwlwifi 11n_disable=1 swcrypto=1 bt_coex_active=0
alias symbol:rtl92c_dm_bt_coexist rtl8192c_common

also I put this into iwlmvm.conf
options iwlmvm power_scheme=1

I don't understand why usb tethering with phone works fine, but using my adapter from the laptop doesn't work well but times out a lot and then reconnects eventually.
