Gilbert Dion, as per http://www.samsung.com/ca/support/model/NP-R580-JS03CA an update to your computer's buggy and outdated BIOS is available (11JB). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) If the issue is still reproducible, please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-11jb -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1525270 Title: Wi-Di Realtek 8192E disconnects after a while and fails to reconnect Status in linux package in Ubuntu: Incomplete Bug description: A few minutes after booting my Samsung R580 laptop, the Wi-Fi disconnects and it fails to reconnect until I restart the machine.
