8.10 kernel 2.6
KDE 4.1
kubuntu 8.1
Wireless network: speedTouch
User: Old version of Windows XP

Remove network-manager-kde package (or something like this, I don't remember the name exactly).

Open /etc/network/interfaces as root (kdesudo kate /etc/network/interfaces)

Assuming that you own a wired connection, paste the following to that file:

Code: Select all

iface eth0 inet static
address 192.168.1.5
netmask 255.255.255.0
gateway 192.168.1.254

where 192.168.1.5 is your IP address and 192.168.1.254 is your gateway.

In the case of a DHCP connection, use this:

Code: Select all

auto eth0
iface eth0 inet dhcp

If you use a DHCP wireless connection, try this:

Code: Select all

iface wlan0 inet dhcp
wireless-essid XXXXXXXXXXX
wireless-key XXXXXXXX

or, if it's static:

Code: Select all

iface wlan0 inet static
address 192.168.1.5
netmask 255.255.255.0
gateway 192.168.1.254
wireless-essid XXXXXXXXXXX
wireless-key XXXXXXXX

Then, open, also as root, /etc/resolv.conf (kdesudo kate /etc/resolv.conf).

Just edit one line:

Code: Select all

nameserver 192.168.1.254

where 192.168.1.254 is your DNS.

Then, open a terminal (konsole) and type:

Code: Select all

ifdown ifc0
ifup ifc0

where ifc0 is the network interface you're using to connect (eth0 for wired connection and, probably, wlan0 for wireless connection).

Now you have internet to solve this problem.

I have the same problem, but my wireless card is:

Broadcom BCM4318 802.11g

My system is:

Kubuntu KDE 4.1.2
Kernel 2.6.27 generic
Ubuntu 8.1

The problem it's that I can't connect to internet, the wireless card hasn't been detected by the Kubuntu system because any wlan is detected.

I don't know what to do! :-S
I've heard that my wlan card is not compatible with Kubuntu! It's that true?

Broadcom cards require the firmware to be cut from the Windows driver. There should be instructions for performing this and then installing the firmware available on the internet. Once this has been done then you should be able to scan for and connect to wireless networks.

It is Illegal to distribute this firmware due to the license on the Windows driver.

Mmmm thats sounds like I have to change my card or my kubuntu. I'm going to try with "UbuntuStudio".

Do you have a recomendation to work with sound files and autocad files in Linux?

Your card is supported by Kubuntu, once you have cut and installed the firmware.

Only audio editing application I know is Audacity, nothing about Autocad.

Ok .
You are sure that I should remove network-manager? As I said before my Kukbuntu seems to see the connection but somehow it does not connect. How about web key, or some feture about firewall or something in the router?

Unless you have MAC address filtering ( If you do not know what this is, ignore it ) nothing should stop you connecting. This is likely because of the broken Network Manager frontend for KDE.

I would recommend installing Wicd as a replacement Network Manager. Uses Gtk unfortunately, but is fast, unobtrusive, reliable and doesn't do nothing too fancy ( VPN for example ). Which is what a network manager should be.
