WIFI randomly disconnects

Hi everyone,

After a while of connecting to my WLAN, I get disconnected from the network (and asked for my password). I use NetworkManager, but in order to get some debug details, I stopped it and used wpa_supplicant.

Here's the output of wpa_supplicant when I get disconnected from the network

nl80211: Drv Event 20 (NL80211_CMD_DEL_STATION) received for wlp0s20f3
nl80211: Delete station -------:f5:88
nl80211: Drv Event 39 (NL80211_CMD_DEAUTHENTICATE) received for wlp0s20f3
nl80211: Deauthenticate event
wlp0s20f3: Event DEAUTH (11) received
wlp0s20f3: Deauthentication notification
wlp0s20f3:  * reason 12 (BSS_TRANSITION_DISASSOC)
wlp0s20f3:  * address --------:f5:88
Deauthentication frame IE(s) - hexdump(len=0): [NULL]
wlp0s20f3: CTRL-EVENT-DISCONNECTED bssid=da:7d:7f:a7:f5:88 reason=12

Here's the output of dmesg when that happens:

Nov 24 17:05:16 galileo dhcpcd[2906]: wlp0s20f3: carrier lost
Nov 24 17:05:16 galileo kernel: wlp0s20f3: deauthenticated from --------:f5:88 (Reason: 12=<unknown>)

Please, let me know if you need anything else.

Re: WIFI randomly disconnects

reason 12 (BSS_TRANSITION_DISASSOC)

12    BSS_TRANSITION_DISASSOC    Disassociated due to BSS transition management

So I guess your wireless might be trying to cut over to different ap with the same SSID(?)

I skimmed wpa_supplicant.conf and didn't see a way to disable.

You could try iwd in place of wpa_supplicant, the wiki for networkmanager describes the needed steps.

Turned out to be a problem on the router. Thank you for your time.

kellett: Be advised that we have not seen brbrbr90 on the forums since last year, and this is a bit of an old thread.

I'll leave this open for a response.  If you don't want to wait, go ahead and open a thread you will own.  Link back to this one if you think it relevant.
If you do open a new thread, please report this one and a moderator will close it.

Thanks, and welcome to Arch Linux.
