After login WLAN takes time to connect

keibak · 2018-09-11 16:43:03

Hi,

I've set up an new computer with an new wireless card and I've noticed that after login into KDE, it takes a considerable amount of time until a wireless connection is established.

Browsing through the logs, the suspious repeated message is

CTRL-EVENT-SCAN-FAILED ret=-22 retry=1

Searching through forum, wiki and Google shows that this might be a speciality of Broadcom chips. Most posts hint to disable mac randomization. Unfortunatelly this had no effect for me.

The wireless card in question is a Broadcom BCM4360 running with the Broadcom 802.11 Linux STA wireless driver. It's working fine, but only the long connection time is annoying.

I'm wondering, where to search next.

For completeness, the complete first connection logs are attached below:

Btw, I disabled mac randomization through

# /etc/NetworkManager/conf.d/90-disable-randomization.conf
[device-mac-randomization]
wifi.scan-rand-mac-address=no

[connection-mac-randomization]
ethernet.cloned-mac-address=stable
wifi.cloned-mac-address=stable
