[Bug 1277598] Re: 8086:4227 [Lenovo ThinkPad T60] WLAN connection break under load (iwl3945)

 

TxSx, as per http://download.lenovo.com/express/ddfm.html an update to your BIOS is available (2.27). 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.
