WIFI/ KNetworkmanager: very good at one netbook, weird behaviour at another one.

Thanks, Leslie, Nils and Everybody for the feedback so far.

Of course, I bear this in mind, but first I look for a less drastic solution.

When I installed WICD, I did remove Networkmanager - I was already aware about
the problem you refer to.

Taking into account this feedback and info I found elsewhere, it is worth
looking at this issue.

In one attachment you will find the terminal output of the netbook in question:
the HP Pavilion: both with and without the WIFI connection switched on.
While writing this reply message, I found a 2nd "workaround": UNchecking the
box "enable wireless", and checking it again. After doing so, the WIFI
connection seemingly goes on without further interruption.
In a 2nd attachment, you will find the terminal output of the Eee PC 1001 HA -
the one with the correctly working WIFI connection.

In the attachment "HP...Pavilion...", you will find probably all the hardware
info you need.
Respectfully yours,
