Wifi randomly disconnects

Hi, I got disconnects of the wifi at any time in the day randomly showing this message :

wlp5s0: CTRL-EVENT-DISCONNECTED bssid=84:be:52:b2:bf:53 reason=4 locally_generated=1

This is in a Laptop with dual boot (Windows / Arch 4.10.11-1). Windows doesnt show any disconnection.

My wifi network card  :

05:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b)
        Subsystem: Intel Corporation Dual Band Wireless-AC 7260
        Kernel driver in use: iwlwifi
        Kernel modules: iwlwifi

I use connman + wpa_supplicant , connman or wpa_supplicant reconnects almost immediatly (1 - 1.5 sec) but breaks every task that I'm doing at that moment (navigation, download, games).

I tried :

- Connecting only with wpa_supplicant manually (as wiki instructs), same error disconnects :

- Downgrading wpa_supplicant to 2.5-3 , same disconnects.

- Downgrading firmware to previous version for iwlwifi, same error :
linux-firmware-20161222.4b9559f-2-any.pkg.tar.xz

- Modified parameters /etc/modprobe.d on/off, same error:

options iwlwifi powersave
options iwlwifi swcrypto
options iwlwifi 11n_disable

- Change channel in modem/router, same error

- Same error with Linux LTS 4.9.24

- Opened the laptop and disconnected the antenna and connected again, same error .

Any ideas what else can I try? ..

Re: Wifi randomly disconnects

I have the same network card, and I am having a similar issue.

Network card:

05:00.0 Network controller: Intel Corporation Wireless 7260 (rev bb)
        Subsystem: Intel Corporation Dual Band Wireless-AC 7260
        Kernel driver in use: iwlwifi
        Kernel modules: iwlwifi

At boot, the wifi works fine. Anywhere from 5-20 minutes later however, I see the following errors in the kernel log:

The wireless interface goes down, and I can't bring it back up, except for a reboot. My computer is also dual booting Arch and Windows, and is up-to-date on all the core arch packages.

Re: Wifi randomly disconnects

This can happen if the signal is too weak. Have you another OS to try? I often have experienced these kind of problems with weak (or saturated signals). However booting into Windows often shows the same problems. Are there others network with the same channel (or a close channel) in the vicinity? If you control the wifi, have you tried to configure your wifi router to use another channel?

Re: Wifi randomly disconnects

According to the OP:

Windows doesnt show any disconnection.

I can confirm that for me as well, everything is fine on Windows. I have also tried networks in both the 2.4 and 5 GHz bands, without any change in the problem. The signal strength is fine.
