Martin Schröder, as per http://www.dell.com/support/drivers/us/en/04/Product/latitude-e6520 an update is available for your BIOS (A17). If you update to this, does it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Thank you for your understanding. ** Tags added: bios-outdated-a17 ** Tags removed: kernel-bug-exists-upstream ** Tags added: kernel-bug-exists-upstream-v3.10-rc6 needs-upstream-testing ** Tags added: regression-potential ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1191510 Title: Wifi disconnects every 10 seconds in WPA/WPA2 enterprise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1191510/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
