If you don't do that, both nm and wicd would fight each other configuring the wifi interface. In the end none of them wins and there is only intermittent connection. OTOH, if you made sure that only one of nm or wicd wass installed at a time, I would assume that the reason is the kernel driver for your hardware. You can find out which hardware is installed in your machine with the command sudo lshw -C network in a terminal. If you tell us which hardware is in use, it may be easier to determine what could be done to achieve a reliable wifi connection.

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 you installed wicd, did you remove networkmanager?

When I installed WICD, I did remove Networkmanager - I was already aware about the problem you refer to. > OTOH, if you made sure that only one of nm or wicd wass installed at a > time, I would assume that the reason is the kernel driver for your > hardware.

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. > If you tell us which hardware is in use, it may be easier > to determine what could be done to achieve a reliable wifi connection. In the attachment "HP...Pavilion...", you will find probably all the hardware info you need. Respectfully yours, Bas Roufs -- ==================== Bas G.
