[Bug 1108798] Re: iwlwifi module - high ping after resuming from suspension


Michał Dobrzański, as per http://download.lenovo.com/express/ddfm.html
an update is available for your BIOS (1.09/1.17). 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.
