Daniel Holm, as per http://www.sony.co.uk/support/en/content/cnt-dwnl/SVP1321M2E/list#os1 an update to your BIOS is available (R1044V7). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything? If it doesn't, 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
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Description changed: - Hi, + Using a Sony Vaio Pro 13 with Ubuntu 14.04 the wifi keeps dropping. Sometimes all the time, at times after a bit longer (~10 min). A few packages ago it didn't drop, but was really, really, slow. Now it completely drops. Adding the following to modprobe.conf made no change: + options iwlwifi 11ac_disable=1 + options iwlwifi 11n_disable=1 - Just got myself a Sony Vaio Pro 13 and installed Ubuntu 14.04. All - packages is the latest. + After each new row I ran: + sudo modprobe -rfv iwlwifi + sudo modprobe -v iwlwifi - The wifi keeps dropping. Sometimes all the time, at times after a bit longer (~10 min). - Netwiork Managers Connection information doesn't tell me what module is in use, but lsmod contains iwlwifi, which should be the module that the hardware uses since Linux 3.13. - - A few packages ago it didn't drop, but was really, really, slow. Now it - completely drops.
