Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

It could have been happening before that since I switched out the other router because it was acting weird (not related I don't think, but wasn't dropping connection ... but it had 4 amplified aerials). New router has internal, but my phone is right next to me and its connection is worse (SNR wise) but stable. Laptop is NOT stable. Seems to be similar to Bug #1349108, but that one was a different driver. And I don't want to post the entire log since I've got the dd-wrt, the cisco, cron jobs, and all kinds of stuff going to my syslog, and I checked .. the mrtg run doesn't always preceed the "lost" message, but it was fairly common that it does. The same messages repeat forever (weekly log rotations show from 69 to over 250 occurances per log file). Let me know what other info I can give. This was stable some weeks ago, but I can't tell you what I changed or when. $ uname -a Linux Taro 3.13.0-37-lowlatency #64-Ubuntu SMP PREEMPT Mon Sep 22 21:56:22 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux $ dpkg-query -W linux-firmware linux-firmware 1.127.7 $ lsmod | grep rtl rtl8188ee 89677 0 rtl_pci 26690 1 rtl8188ee rtlwifi 63475 2 rtl_pci,rtl8188ee mac80211 638933 3 rtl_pci,rtlwifi,rtl8188ee cfg80211 496328 2 mac80211,rtlwifi *** Snippet of /var/log/messages showing problem ... *** Oct 8 01:25:01 Taro CRON[21545]: (root) CMD (if [ -x /usr/bin/mrtg ] && [ -r /etc/mrtg.cfg ] && [ -d "$(grep '^[[:space:]]*[^#]*[[:spac e:]]*WorkDir' /etc/mrtg.cfg | awk '{ print $NF }')" ];
