iwlwifi rebuild

[lieta]

Hi.
How to rebuild iwlwifi driver? Just need to enable CONFIG_IWLWIFI_DEBUG.

[jeremy31]

What exactly are you trying to do?

[lieta]

I want to add debug logs to the driver. Station occasionally disconnects from access point and in wpa_supplicant log I see:

1722493569.290166: wlp0s20f3: Event DEAUTH (11) received
1722493569.290177: wlp0s20f3: Deauthentication notification
1722493569.290184: wlp0s20f3:  * reason 4 (DISASSOC_DUE_TO_INACTIVITY) locally_generated=1

although I'm constantly sending pings from AP to STA.

Any result for

sudo dmesg | grep iwl

$ sudo dmesg | grep iwl

This is exactly where I started. In "How to debug?" capter: "To see more debug prints, CONFIG_IWLWIFI_DEBUG must be enabled."
I don't want to recompile the whole kernel, just iwlwifi driver.

If you run "iwconfig" does it say "Power Management: on"?

Was:

Power Management:on

Turned it off, testing now.
