Federico Sassi, as per http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t540p an update to your BIOS is available (2.16). 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
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, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-2.16 ** Tags added: utopic ** Description changed: - I have a Lenovo Thinkpad T540p with Intel Dual band Wireless 7260AC and the wireless connection isn't working correctly. - It will list the available networks but when trying to connect it will keep asking for the password or when it connects the connection will last only few seconds and the packet loss on a ping will be very high. + I have a Lenovo Thinkpad T540p and the wireless connection isn't working + correctly.
