Ubuntu

wlan only works when i use wifi radar

Asked by Dines683

I am running ubuntu-studio 7.10.

The thing is that the wlan doesn't work unless i am running wifi radar at the same time.

in network settings it says that the wireless connection is not configured, and there is no way to change that unless i
use wifi radar at the same time.

I have a Intel Corporation PRO/Wireless 4965 AG network card which should be supported on ubuntu-it was working fine under ubuntu-desktop 7.10

in wifi radar i get a message that there is no WPA.

Does anyone have a clue of what is wrong?

I had a similar problem and resolved it this way.

A. Install network-manager-gnome using synaptic. It can set up network-connections automatically and even changes them if it is necessary (e.g., when you want to log in into another wireless network or just plug a network cable into your computer).
B. Open '/etc/network/interfaces' with your favorite editor (e.g., nano) and put a '#' before 'iface wlan0' (and before 'iface eth0' if you want your wired network controlled by network manager, too). This tells Ubuntu not to manage your network devices anymore.

You have to set network-manager options to 'start network-manager automatically on log-in' and you are done. Connecting to any network is as easy as right-clicking on the network-manager symbol in the Panel and select the name of the network.

However, this only works if you use DHCP (no static IP-address)

hmm

i dont have a "iface wlan0" in my /etc/network/interfaces

this is my file

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

A little correction

It turns out that my wireless does work well now, but still this is my /etc/network/interfaces file:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

And furhter when i shut down my system i get some messages, that wasn't there before i installed the manager.

Don't know if this is of any importance...
