Description emsa 2013-09-01 09:45:18 UTC 
Description of problem:

Wlan intermittent drops

Version-Release number of selected component (if applicable):

Fedora 19 / 3.10.9-200.fc19.x86_64 on MacBook Pro

Actual results:

The wlan loses network connection, pinging another host on my local network gives pingtimes from 0.6ms to 4ms then I get "Network Unreachable" for a while then I get the same ping times back again.

iwconfig reports "Link Quality=70/70" also under network drops but "Signal Level" will go down from 7 to 0 dBm.

Controller is reported as:

03:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)

Happy to provide more details ...
Comment 1 emsa 2013-09-01 10:38:15 UTC 
Should say "Destination Host Unreachable" not "Network Unreachable".


As an update I also mention that the connection not always comes back and I do need at times to restart the wlan to get the connection back
Comment 2 emsa 2013-09-01 11:17:17 UTC 
Once more: I switched to "3.10.4-300.fc19.x86_64", with this kernal I do not get any drops (so far). Ping times vary widely but overall it seems stable ...
Comment 3 emsa 2013-09-04 17:01:10 UTC 
It does happen even with the older kernel but it /seems/ like the likelihood of this happening is increased by suspend/resume.
Comment 4 Josh Boyer 2013-09-18 20:38:48 UTC 
*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs.

Fedora 19 has now been rebased to 3.11.1-200.fc19.  Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you experience different issues, please open a new bug report for those.
Comment 5 emsa 2013-09-28 08:27:32 UTC 
The issues remain the same in 3.11.1-200.fc19.x86_64
Comment 6 emsa 2013-10-05 15:33:30 UTC 
Updated to 3.11.2-201.fc19.x86_64 where to problems seems to be worse.
Comment 7 Michele Baldessari 2013-10-15 21:47:34 UTC 
I have the previous version of the card and it works quite well
02:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)

normally when the driver has issues it spews messages in var/log/messages (look for brcmsmac). Do you get any warnings/messages?
Comment 8 emsa 2013-10-23 17:12:45 UTC 
No nothing from brcmsmac, I get stuff like below.

After this I open the applet, turn the wireless off then on again and the network connects again.

Comment 9 filip.slunecko 2013-10-31 06:16:46 UTC 
I had the same problem. I run b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.o again on the new kernel and it seems to help.
Comment 10 Michele Baldessari 2013-12-01 11:04:54 UTC 
If messages has no mention of errors, there is not much we can do (short of
recompiling a kernel with CONFIG_BRCMDBG=y and post the messages here).

Maybe try a more recent firmware as suggested by Filip?
Comment 11 Justin M. Forbes 2014-03-10 14:45:37 UTC 
*********** MASS BUG UPDATE **************

This bug has been in a needinfo state for more than 1 month and is being closed with insufficient data due to inactivity. If this is still an issue with Fedora 19, please feel free to reopen the bug and provide the additional information requested.
Comment 12 emsa 2014-07-16 09:33:04 UTC 
Now updated to Fedora 20 (updated this issue accordingly), using broadcom-wl/kmod-wl/akmod-wl (rpm-fusion).

Still I have the same issues, wlan drops and then after a while it usually return to working state.

I have not been able to figure out where the issue lies, can it be that the hardware/firmeware doesn't like my netgear router?
Comment 13 Josh Boyer 2014-07-16 12:07:57 UTC 
We don't support the proprietary broadcom drivers.
