ceni

Open a terminal, and enter:

sudo ceni

Choose the card you want to reconfigure (cursors up and down), then hit [Enter]. Next, first remove the configuration, then repeat the selection of the card.
If it is a wireless card you try to set up, you first have to Scan or Roam. Use the Tab key (left of Q) to jump through the input fields and [Space] or [Enter] to select. If you are on a router that distributes IP addresses via DHCP, be sure to select that option.
If your network works but you cannot connect to websites, be sure that you have chosen a DNS server, either in your routers setup, or in Ceni. The DNS server that work well are:

    8.8.8.8
    8.8.4.4
    208.67.220.220
    208.67.222.222

Choose one or two of these and enter them separated with a comma in Ceni's interface.

wicd

For users who installed Wicd, please follow these steps:

• using a configurable menu tool like 9menu (shipped with "Oyster")
• using grun and bind it to a key combo, for example Alt - F2 (shipped with "Oyster")
• via autostart (refer to the manual page of your Window Manager)
• through a menu in a panel (not every WM supports panels)
• through the terminal

GRUB is the default bootloader on most Linux systems.

On some computers it happens that after installing a Linux OS all other entries (for example to start Windows or other Operating Systems) in the boot menu disappear. Don't worry about this. Start the LinuxBBQ System Tool (Openbox menu -> Help) and select to "Update GRUB". Another way is to invoke:

sudo update-grub

Then reboot (sudo reboot).

If the menu entries are still missing, you have probably more than one hard drive in your computer. Reboot into a live system (from USB) and then Start the LinuxBBQ System Tool (Openbox menu -> Help) and select to "Rescue GRUB".This should do the trick.
If it still fails, you can do it manually: First find out which of the hard drives carries the Linux OS you want to have booted up by default:

sudo fdisk -l

This will show a rather long list of recognized devices. There should be an entry that looks similar to this:

/dev/sdb1    *    2048    204802047    102400000    83    Linux

Note the asterisk '*' that shows us that this partition is the boot partition, in our example sdb1. The GRUB should now be written into /dev/sdb (without number)

sudo grub-install /dev/sdb

After this, update GRUB again:

sudo update-grub

and reboot. If it is still not fixed, you should follow the guide on how to install GRUB from a chrooted environment.

install GRUB from chroot

Assumption 1: Linux is installed on /dev/sda1 but is not accessible via grub
Assumption 2: /dev/sda1 is the root partition, and you do not have a separate boot partition
Goal: reinstall GRUB in mbr of /dev/sda:

Boot from LiveCD or USB, then in the terminal window enter:

TARGET=/media/sda1
sudo mkdir -p $TARGET
sudo mount /dev/sda1 $TARGET
sudo mount --bind /dev     $TARGET/dev
sudo mount --bind /dev/pts $TARGET/dev/pts
sudo mount --bind /proc    $TARGET/proc
sudo mount --bind /sys     $TARGET/sys
sudo chroot $TARGET /bin/bash

This places you in a root terminal on the system. Do whatever you want to do there, e.g. re-install GRUB

grub-install /dev/sda
update-grub

To exit from chroot: press control-D or enter exit

This brings you back to where you were in the live session and you can unmount

sudo umount -l $TARGET/dev/pts
sudo umount -l $TARGET/dev
sudo umount -l $TARGET/proc
sudo umount -l $TARGET/sys

Thats it.
