What does rfkill list say when you don't have WiFi? I can't see any problem in dmesg.

Sorry for late reply , unfortunately i couldn't think to check it. But inxi -Fxz was like this: Card-1: Intel Wireless 7265 driver: iwlwifi bus-ID: 02:00.0 IF: N/A state: N/A mac: <filter>
Are you sure the dmesg output you attached was taken after the NIC disappeared?
Are you using tkip encryption? Can you try with AES or without security?
Ping?

What is happening here is that WiFi needs to run calibrations, but can't because the radio is claimed by the BT core for way too long. This is most probably a bug on the BT side. You can check that you have the latest FW for BT or try to disable BT. I'll leave this bug open for a few more days and then close it.

BT was disabled when i get this wi fi error every time. How can i check for latest FW?
You have the latest Wifi firmware. For the BT firmware you can check in linux-firmware.git repository.
(In reply to Emmanuel Grumbach from comment #20) > You have the latest Wifi firmware. For the BT firmware you can check in > linux-firmware.git repository. It is on 1.157.19
This number doesn't mean much for upstream. Since we can't do anything from the wifi did anyway, I'm closing this.
