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


TxSx, thank you for apport-collect'ing. Regarding your comments https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1277598/comments/21 :
>"These guys seem to have the same hardware and the same problems:

That report has nothing to do with this one, as the original reporter
noted in the Bug Description how the sound quality is poor, not the WiFi
is disconnecting.

>"I'm also having sound problems in with fullscreen videos."

As this bug report is only focused on WiFi disconnections, this is outside the scope of this report. You are welcome to file a new report about it in Ubuntu via a terminal:
ubuntu-bug audio

>"My lspci:"

You wouldn't need to provide this as it was already captured during your
apport-collect, among other helpful information ->

Despite this, could you please answer the following questions:
+ Did this problem not occur in a prior version of Ubuntu?
+ In Trusty only, could you please test the latest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc4-trusty/ and advise to the results?
