Broadcom BCM43228 error: ERROR @wl_notify_scan_status : wlan0 Scan_results error (-22)

Hello!

I have a problem with my broadcom wifi device on my Linux Mint 17.2 Rafaela (64 bit).

The device is: Broadcom Corporation BCM43228 802.11a/b/g/n.
The kernel is: 3.16.0-57-generic #77~14.04.1-Ubuntu SMP Thu Dec 17 23:20:00 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux.
The driver is: Linux STA Broadcom 802.11 (package bcmwl-kernel-source).

Now and then I found sometimes this message in the /var/log/syslog:

Code: Select all

ERROR @wl_notify_scan_status : wlan0 Scan_results error (-22)
What is worst is that sometimes (less frequently) the wifi stops working (for 30 seconds or so, let's say), while other devices connected to my modem still work fine. Then, the wifi connects to the modem again.

I read on the internet that many have this problem and a solution could come disabling power management:

https://wiki.debian.org/wl

Actually, power management is off by default, so I cannot solve the problem in this way.

Any suggestion? Thank you for your help!

Maybe I found a solution. It seems that I had to upgrade kernel.

RIght now I am using Linux 3.19.0-61-generic #69~14.04.1-Ubuntu SMP Thu Jun 9 09:09:13 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux, but also Linux 3.16.0-73-generic #95~14.04.1-Ubuntu SMP Thu Jun 9 08:00:04 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux seems not to have the problem.

There is also some unexpected problem with the default recommended kernel 3.16.0-38-generic. In the folder /lib/modules/3.16.0-38-generic there was not the required module wl.ko. To have it I needed to reinstall the kernel. That's strange, because I am sure I used that kernel just after installing and the wifi was working.

Maybe I spoke too early. Now I get this error (frequently)

Code: Select all

ERROR @wl_inform_single_bss : cfg80211_inform_bss_frame error
Then the wifi loses the connection with the modem.

Could that be due to too many modems in my neighbourhood?

Any suggestion?

Thanks!

I am back to the Linux Mint 17.2 default kernel: Linux 3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux.

I got once more
ERROR @wl_notify_scan_status : wlan0 Scan_results error (-22)
and many
ERROR @wl_inform_single_bss : cfg80211_inform_bss_frame error
Any suggestion? I have no more ideas...
