type iwconfig if you don't have it get wireless-tools I believe it's 'apt-get install iw', then you can run iwconfig and post the output.

I'm glad to hear your hardwire is working again. This should make things easier to troubleshoot. I'm going to have to take a closer look at your hardware in the morning because as of this moment I'm a little drunk, but I will have another look at it in the morning. I don't believe wicd is what we should be concentrating on that the moment. It's just a software to make it more convenient to connect to wireless networks. We are going to get you online fist using nothing but command line and then we will look into a nice GUI for you.

tke1384 - I have realised that after restarting my ubuntu computer that I lose my wired connection again however if I enter the commands you suggested earlier:-

$ sudo ifconfig eth0 up
$ sudo dhclient eth0
$ ifconfig eth0

my wired connection works again immediately.

I have removed wicd and also run update manager but whenever I restart I lose the wired connection until I enter the settings in terminal again.

Do you have any ideas how to make the changes I am doing in terminal permanant?

I'm still concerned with the instructions I followed which caused me to lose my wired connection originally. These are the instructions I followed below:-

3.1. Disable Free Drivers
Firstly, all releases since Ubuntu 6.06 have the open source bcm43xx driver, which was replaced in 8.04 by b43 and b43legacy, see WifiDocs/Driver/bcm43xx. If this driver doesn't work for you, then you should disable it, because it will conflict with ndiswrapper. To disable it, add blacklist bcm43xx lines for each driver to the modprobe blacklist.
echo -e "blacklist bcm43xx\nblacklist b43\nblacklist b43legacy\nblacklist ssb" | sudo tee -a /etc/modprobe.d/blacklist

Do you have any ideas how to undo these changes I made?

You can put the commands in
/etc/rc.local

repo - I found the folder you suggested but not sure where to enter the commands.

Here's what rc.local contains when I open the file in display mode:-

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exit 0

Where should I enter the commands?

After the line
# By default this script does nothing.
Then

repo - When I enter the commands as you describe I am not able to save the file as it states I do not have permission to save the file?

Am I entering them correctly as below?

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
ifconfig eth0 up
dhclient eth0
ifconfig eth0
exit 0
sudo chmod +x /etc/rc.local

You need to edit the file as root

You need to add
Then save the file
Then make the file executable
In a terminal type

repo - Thank you. I just followed your instructions and wired connection works after restart!!!

Do you have any ideas on how to start to get my wireless connection working?

What is the output from
What have ou tried until now?
Sorry, to lazy to read the whole thread :-)

repo - Here's the results of sudo iwconfig:-

steve@dharma-ubuntu-desktop:~$ sudo iwconfig
[sudo] password for steve:
lo no wireless extensions.

eth0 no wireless extensions.

pan0 no wireless extensions.

steve@dharma-ubuntu-desktop:~$

After installing ubuntu I could not establish any connection with network manager.

I then uninstalled network manager and installed wicd which allowed me to connect via wired connection (I had selected manual settings for static ip address to be assigned as I have a home network) which worked fine until I disabled drivers following instructions how to us nsdwrapper at ubuntu website. Not sure what I was doing and got lost really, but my connection stopped and wicd stopped working as soon as I disabled the drivers as per the instructions below:-

3.1. Disable Free Drivers
Firstly, all releases since Ubuntu 6.06 have the open source bcm43xx driver, which was replaced in 8.04 by b43 and b43legacy, see WifiDocs/Driver/bcm43xx. If this driver doesn't work for you, then you should disable it, because it will conflict with ndiswrapper. To disable it, add blacklist bcm43xx lines for each driver to the modprobe blacklist.
echo -e "blacklist bcm43xx\nblacklist b43\nblacklist b43legacy\nblacklist ssb" | sudo tee -a /etc/modprobe.d/blacklist

Before this wicd was able to detect my wireless connection but I could not connect wirelessly after entering the wireless network settings and password. Wicd would just freeze. Earlier in this thread I was advised to use nsdwrapper but couldn't work out how or what to do.

My wireless network card is netgear wg311v2

as root edit
remove the following lines

Reboot, and see if wicd works

Repo - I removed those lines, reinstalled wicd and rebooted but wicd still dosen't work. It pops open for a second then disappears.

Try
If that doesn't work, try to reinstall network manager


Once networkmanager or wicd works, try to see if the wireless connection is recognized.

If not you will need to use ndiswrapper.

repo - I tried:-

apt-get --purge remove wicd
sudo apt-get install wicd

but wicd still shows up in applications but wont start.

when I

sudo apt-get instal network-manager-gnome

I get this message

root@dharma-ubuntu-desktop:/home/steve# sudo apt-get instal network-manager-gnome
E: Invalid operation instal
