Often I receive the message : Problem in ubunt, do you want to send the messaage?
Often my laptop (Dell Latitude) looses contact with wifi, only to be repaired by restarting the computer.
This happens for all after changing a user and a moment of computersleep

You say:

* Often I receive the message : Problem in ubunt, do you want to send the messaage?

* Often my laptop (Dell Latitude) looses contact with wifi, only to be repaired by restarting the computer.

But those are two separate issues. Please choose one issue you would like this bug to be about.

Thanks for your rapid answer.
The wifi problem is worrying me the most.

There is no connection between the two?

Sincerely

No the issues are not related. The first one means something has crashed, whereas there is no "something" in userland that can affect wireless (that I can think of).

OK, next time the wifi stops working, before rebooting, please run:

  dmesg > curdmesg.txt

and send us the file 'cusdmesg.txt'.

This time wifi disconnected while I was actively internetting.
I join the file you asked.

Thanks!

Yes indeed the last messages in your kernel log are about wifi:

When wifi dies it seems the system tries to use ethernet which is also not connected. But I think the main issue is wifi.
