wpa_supplicant disconnects exactly 1 minute after connecting [BCM4350]
I'm having trouble with my Broadcom BCM4350 adapter. I can connect to networks just fine,
and everything appears to work, except that exactly one minute after establishing a connection, the
connection will break, until automatically reconnecting in approximately 3 seconds. This process repeats
continuously.
The message
wpa_supplicant[403]: wlp58s0: CTRL-EVENT-DISCONNECTED bssid=**:**:**:**:**:** reason=0 locally_generated=1appears in the system log when these disconnects occur (MAC address removed). No other log messages directly
precede these messages, and the disconnect messages consistently occur exactly 1 minute after the preceding CTRL-EVENT-CONNECTED message.
Does anyone have any idea what may be causing these disconnects to occur? It seems that the exact 1-minute time
window might give some clue as to what is happening, but I have no idea where to look.

I'd bet my left mouse button you have other networking processes running. Check the output of `ps` or `systemctl list-units`.

3173 pts/1 00:00:00 psWhile I am not particularly well versed with how my network stack works, NetworkManager is the only process that looks remotely suspicious to me, and as I understand that just handles the gui while delegating to wpa_supplicant. Do you see anything that would obviously be interfering with wpa_supplicant?

Re: wpa_supplicant disconnects exactly 1 minute after connecting [BCM4350]
No, NetworkManager will most definitely interfere with wpa_supplicant ... that is unless you're only using NetworkManager and it is starting wpa_supplicant. If you started/enabled wpa_supplicant, or ran wpa_supplicant directly from the command line, then NetworkManager definitely needs to be disabled.

Re: wpa_supplicant disconnects exactly 1 minute after connecting [BCM4350]
I double checked, and wpa_supplicant is not enabled on its own, but is being started by NetworkManager. As a sanity test, and to ensure nothing else was starting wpa_supplicant, I diabled NetworkManager, and wpa_supplicant did not start. So it doesn't seem my problems are being caused by interference between the two.

Re: wpa_supplicant disconnects exactly 1 minute after connecting [BCM4350]
Did you figure out the issue ? Exact same hardware and facing the same problem.
Edit: definitely a driver issue. I switched to an USB adapter and kept the same arch config, my problems disappeared.
