Connect to Wireless Network, no internet connection

Hi, I recently installed Backtrack 5 R3 on my Toshiba NB255 laptop.

I can connect to my wireless network with wicd, but theres no internet access. Ping fails to connect and firefox can't connect to any servers either. After doing iwconfig and ifconfig, I can't see anything out of the ordinary, no dropped or erroneous packets according to ifconfig.

When I connect through ethernet to my router, wicd stalls at the ip assignment step.

I've tried starting networking through

Code:

---

start networking

---

and

Code:

---

/etc/init.d/networking start

---

, but I can't get it to work.

I'm getting good signal, so that isn't it.

Again, I successfully connect to the network, just no internet. Any ideas?

Also possibly worth noting, when I run a LAN device discovery tool, such as netdiscover, I am only able to find the router itself (192.168.0.1).

Any help would be appreciated!

Would you please post the ifconfig and iwconfig output?Are you using HDD install, VM, USB?..The wifi device chipset and type of authentication used (wpa-wpa2, wep, open)?

Luck.

I have a HDD install, alongside Ubuntu and Windows.

I'm in a WEP encrypted network, and I have the encryption settings correctly configured

I'm not sure what lo could be to be honest, so I posted it anyway!

I do not see anything wrong, as a matter of fact, wlan0 has been authenticated and it was offered a valid ip (192.168.0.104), this ip offered came from DHCP server...Link quality is little over 70% (-59dbi is quite good)..

Please, try to do this: Boot up with LiveCD, and try to connect to router..See if it works...

you also might make sure wicd is set to wlan0 and eth0 in pref's as default i think is wlan1 and eth1
if you were just trying to get wicd to scan

When booting from live disk, I started networking with "start networking" and then opened wicd. When I opened it I got an error saying "Could not connect to wicd's D-bus interface. Check the wicd log for error messages." After I clicked okay, everything opened normally.

I connected again successfully to the network but still no internet. :(

Association, authentication and DHCP all seem to be working. This suggests the problem is in route and/or dns. There are many tutorials on how to troubleshoot this eg http://www.tecmint.com/linux-network...ting-commands/

Make sure you have internet service active or check your router configuration as suggested by VulpiArgenti, I certaily belive the issue is not with BT5...

By the way, have you tried using ethernet port (Wired)?...

I have tried other networks and I am getting the same issues surprisingly! I tried ethernet on my home network but it stalls at "getting ip"
