how to edit interfaces file in /etc/network/interfaces?

[basx]

Hi all:

I need to add some additional info about my wired connection but I don't have gedit and KATE won't let me save the changes.

So how do I edit the interfaces file in /etc/network/interfaces directory?

Thanks!

User can't change system files, so it is necessary to run your text editor in "root" (aka "Super User") mode.

Alt-F2 "kdesudo kate" with no quote marks, and then entering your password at the prompt, will open kate in Super User mode.

Alt-F2 "kdesudo kate /etc/network/interfaces" will open kate and the file that you want to edit.

Thanks very much. That worked perfectly and I'm now connected to the Net via cable.

Now to work on getting the wireless Smiley

KMenu --> System --> Hardware Drivers

One of the drivers listed should be your Broadcom wireless chip. Click on the "activate" button.
What happens is that fw-cutter will be downloaded from the repository (so, your wired connection must be working) and it will read your wireless chip firmware and "cut" out the driver and set it up.

Your next step will be to use KNetworkManager to set up your wireless ESSID & Password and then connect.

Lucid came with knm-runtime and some knetworkmanager guis and stuff installed. They immediately found my wireless and had no problem connecting, but they won't connect to your now unsupported Broadcom chip (unsupported by both Broadcom and Ubuntu). However, Knetworkmanager may give you problems because it is a work in progress, so ....

Using Synaptic (install it if you haven't yet) install the following packages:
python-urwid
python-wicd
wicd
wicd-cli
wicd-curses
wicd-daemon
wicd-gtk


and then completely removed the following packages:
modemmanager
network-manager
network-manager-openconnect
network-manager-openvpn
network-manager-pptp
network-manager-vpnc
knm-runtime
network-manager-kde
plasma-widget-networkmanagement

Use wicd to setup your wireless device. Then reboot.

Thanks. I just checked the Hardware drivers and there's no Broadcom driver just an Nvida that's not active. That's weird because I downloaded the STA and the source driver (via the cable). I also downloaded later on the b43 fwcutter on the advice from the French forum but that didn't work out.

So, here are my questions:

Should I deinstall all the Broadcom drivers I have and then download the Broadcom STA driver once again?

Thanks!

I'd plug in a cat5 ethernet cable from the back of your wireless router (which usually has 1 to 4 extra eth ports) to your PC. Then I'd delete everything related to your previous broadcom wireless install.

Then, I'd follow the instructions here for your particular broadcom chip.

I apologize if this makes everything less clear, but http://wiki.debian.org/bcm43xx (about halfway down the page) seems to indicate that the rndis_wlan module is already present as a kernel module for the Broadcom 4320 chip. If that is not the wifi chip that your adapter uses, then stop.

If it is your adapter's chip, then follow the instructions and use whatever GUI you want to manage the connection. I'm flying very well with network-manager, but wicd may be your choice. It will mean removing any other wifi drivers you may have already installed.

If this doesn't make sense or doesn't feel right, then press on with the other recommendations.
