Acer 5755G Problem with internet conectivity

I’ve recetly installed Backtrack 5r3 ,
when i start the wicd network Manager i’ve an error :

“Could not connect to wicd’s Dbus interface. Check the wicd log for error messages.”

i didn’t find the wicd log .
Ps : the ethernet connection dosen’t work also …
i searched in other post but it didn’t solved my problem.
Help .

Hi and welcome to the forum.

i didn't find the wicd log .
Did you look in [b]/var/log/wicd/wicd.log[/b]? You could try locating it:
locate wicd.log

According to this you may also have to add your regular user account to the netdev group and reload DBus:

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):

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:

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

Are you using DHCP or fixed ip address?

With the wired connection, can you ping your router ?
ping -c 5

Can you ping google.com:

ping -c 5 google.com

Can you ping Googles IP address:

ping -c 5 173.194.41.130

OK,

service dbus reload dosen’t return anything .

[quote author=SeZo link=topic=10660.msg80738#msg80738 date=1359156624]

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.

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 .

Yes 5 transmitted , 5 received

Host name unknown

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 ?

Think you ! Now the wired connection work perfectly .
But i didn’t understand your question ! i’ve recently backtrack 5 r3 and i find juste wicd to connect to internet.i didn’t find the NetworkManager.
Ps: i don’t know if it help but i tried sudo apt-get install network-manager
and it show error :"Errors were encountered while processing:
bcmwl-kernel-source
E: Sub-process /usr/bin/dpkg returned an error code (1)
"

OK, wireless …

Can you open a terminal and send the output from:

sudo lshw -C network

and

ifconfig

and

iwconfig

and

rfkill list

and

iwlist scanning

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:

sudo apt-get install --reinstall dkms bcmwl-kernel-source

When that command has finished, run:

sudo modprobe wl

Does your wireless spring to life ?

*sudo apt-get install --reinstall dkms bcmwl-kernel-source : it has stoped with this error :
“Error! Bad return status for module build on kernel: 3.2.6 (x86_64)

  • and : sudo modprobe wl
    FATAL: Module wl not found.

With a wired internet connection … run:

sudo apt-get remove --purge dkms

then

sudo apt-get remove --purge bcmwl-kernel-source

then

sudo dpkg --configure -a

then

sudo apt-get clean

then

sudo apt-get update

then

sudo apt-get upgrade

then

sudo apt-get install linux-headers-generic build-essential

then

sudo apt-get install bcmwl-kernel-source

then

sudo modprobe wl

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