[Bug 995130] Re: BCM4321 Wireless dropping connection randomly with no indication
After further testing over many days, I am almost certain that this problem is caused by the power-saving mode in the Broadcom drivers, which is enabled when the laptop is on battery by the script in /usr/lib /pm-utils/power.d/wireless which runs iwconfig eth2 power on. Manually running iwconfig eth2 power off seems to fix the problem, as does plugging in the laptop. I replaced the pm script with one that always runs iwconfig eth2 power off regardless of battery status, and I have not had any major connectivity issues since then.

[Bug 995130] Re: BCM4321 Wireless dropping connection randomly with no indication
That is possible. It's difficult to notice patterns, because it typically takes me a minute or two to notice that the connection has dropped, since I might be downloading something in the background but only notice the problem when I switch to my browser and try to load a new page. I'm not doing any p2p traffic, but I'm using a script based on youtube- dl to pre-download my subscribed videos to my hard disk so I don't have to wait for them to buffer. I have noticed a few times that running the script was followed shortly by a loss of connectivity, and the same for some other large in-browser downloads. Also I've just installed 12.04 from scratch a few days ago, so I'm still installing packages, and sometimes the apt-get download is interrupted by a connectivity loss event. But still, there are other times when I'm not aware of any specific high traffic that I'm generating, but maybe the website that I'm loading at the time happens to have a bunch of large images or something and is generating a traffic burst. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/995130 Title: BCM4321 Wireless dropping connection randomly with no indication To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/995130/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ok, I'll grab those log files after the next time the connection cuts out, but as I said, I haven't previously seen any log entries appearing in any logs at the time of disconnection. Also, I didn't explicitly say so in my initial report, but the worst part about this is that there is NO indication that connectivity has been lost. In particular, the Wifi icon in the notification area does nto change at all. Also, I can fix the problem temporarily by simply reconnecting to the wireless network, but the same problem always happens again. It looks like the problem MAY be correlated with being on battery power, but I'm not sure. Maybe wifi power saving is to blame? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/995130 Title: BCM4321 Wireless dropping connection randomly with no indication To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/995130/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
