Hi and welcome to the forum.

i didn't find the wicd log .

Did you look in /var/log/wicd/wicd.log?
You could try locating it:
Code: [Select]
locate wicd.log
According to this you may also have to add your regular user account to the netdev group and reload DBus:
Code: [Select]
sudo adduser <yourusername> netdev
sudo /etc/init.d/dbus reload

Think you for your reply,
-i added my username to the netdev .
-the error message didn't show again , but the problém is not resolve : i cannot access internet .
the wicd is open but it didn't show me my wireless network.
*sudo /etc/init.d/dbus reload result :
"Rather than invoking init scripts through /etc/init.d, use service(8) utility, e.g. service dbus reload

Since the script you are attempting to invoke has been converted to an Upstart, you may also user the reload(8) utility, e.g. reload dbus"

Ps : wired connection connect to network (and i have local ip) but internet conection still not working.

OK, you could have reloaded dbus with (as it tells you):
 
Code: [Select]
service dbus reload

the wicd is open but it didn't show me my wireless network.

Go to wicd>Preferences>General Settings
     >Have you got your wireless & wired interface in the adjacent boxes?
If not then you could find out their names with:
Code: [Select]
ip link

Are you using DHCP or fixed ip address?

With the wired connection, can you ping your router ?
ping -c 5 <ip address of router>

Can you ping google.com:
Code: [Select]
ping -c 5 google.com

Can you ping Googles IP address:
Code: [Select]
ping -c 5 173.194.41.130

OK,

OK, you could have reloaded dbus with (as it tells you):
 
Code: [Select]
service dbus reload

service dbus reload  dosen't return anything .

Code: [Select]
ip link

i founded the wireless interface empty , i did the comand (l0 for wireless , eth0 for wired) and i puted in the correspondant fields.

Are you using DHCP or fixed ip address?

i'm using DHCP i think (pereference Client Dhcp (automatic checked))
-in wired connection i have (Use Static Ips (not checked), Use Static DnS (not checked),DHCP Hostname = bt(checked))
-for wireless connection i didn't know .

With the wired connection, can you ping your router ?

Yes 5 transmitted , 5 received

Can you ping google.com:

Host name unknown

Can you ping Googles IP address

Yes 5 transmitted , 5 received

OK, for the wired connection the problem is there is no DNS servers set for name resolution ..

You're going to have to manually assign either the routers IP as the DNS server .. or statically assign your ISP's (or openDNS) DNS server addresses.

Any reason you're using wicd over NetworkManager ?

OK, the Broadcom drivers for your wireless aren't installed, or are broken .. so let's reinstall them.

Make sure you're connected to the internet by an ethernet cable, then open a terminal and run:
Code: [Select]
sudo apt-get install --reinstall dkms bcmwl-kernel-source

When that command has finished, run:
Code: [Select]
sudo modprobe wl

Does your wireless spring to life ?

With a wired internet connection .. run:

sudo apt-get remove --purge dkms
then
Code: [Select]
sudo apt-get remove --purge bcmwl-kernel-source
then
Code: [Select]
sudo dpkg --configure -a
then
Code: [Select]
sudo apt-get clean
then
Code: [Select]
sudo apt-get update

sudo apt-get upgrade
then
Code: [Select]
sudo apt-get install linux-headers-generic build-essential
then

Did the wireless spring to life, or were there any errors ?
