now you dont even getting dhcp lease..
as i said if u're using dhcp, the dhcp server and dns setting is in your router.. nothing to do with your OS.. This post has been edited by ozs: Aug 20 2008, 10:52 PM |

CODE doesnt debian and ubuntu are similar? Similar but not the same. Yes, Ubuntu at earlier stage follow Debian. The filesystem layout and packaging system. But now I think Ubuntu has gone it's own path. Like I said before, it does not follow Debian versioning system. It does not go through strict release system: experimental--> unstable-->testing---->stable. That is why Ubuntu can release new version every few months. Is it really stable? Everytime people file bugs...they will repair it in new release. So which is stable release? Future release? I'm not comdemning Ubuntu, just curious. CODE so what now?? is there anything wrong? Nothing wrong with your iwconfig. Your wireless connected to your router. Are you sure you have check /etc/resolv.conf and tmnet dns is on the first line? How about ping? Does it reply from outside? Something you could check, is the routing table. Try this command: ip route get 1.2.3.4 It should show it's trying to get the ip through your router. Something like this: # ip route get 1.2.3.1 1.2.3.1 via 10.0.0.1 dev wlan0 src 10.0.0.3 cache mtu 1500 advmss 1460 hoplimit 64 |

ok let see this screen shot..
 the numbers of default route and the primary dns is same with my wifi router ip address, that why i dont understand.. i have adjusted the /etc/resolv.conf but still same,, but when using wired connection is going well even the number of primary dns is same with ip address of router.. this is my ip route for wired connection CODE scorps@scorps-laptop:~$ ip route get 1.2.3.4 1.2.3.4 via 10.0.0.2 dev eth0 src 10.0.0.10 cache mtu 1500 advmss 1460 hoplimit 64 scorps@scorps-laptop:~$ for wifi connection CODE scorps@scorps-laptop:~$ ip route get 1.2.3.4 1.2.3.4 via 10.0.0.1 dev wlan0 src 10.0.0.21 cache mtu 1500 advmss 1460 hoplimit 64 scorps@scorps-laptop:~$ Added on August 21, 2008, 1:00 amthis is my network setting,, adsl modem --->>wifi router (as switch, disable security,)>> users | | as pppoe mode gateway for modem : 10.0.0.2 gateway for router : 10.0.0.1 what else yeah?? all in dhcp mode... if connect direct to modem using wired,it's working great but if connect to wifi router using onboard wifi, that's problem happen Added on August 21, 2008, 1:06 am QUOTE(scorps @ Aug 21 2008, 01:48 AM) ok let see this screen shot.. the numbers of default route and the primary dns is same with my wifi router ip address, that why i dont understand.. i have adjusted the /etc/resolv.conf but still same,, but when using wired connection is going well even the number of primary dns is same with ip address of router.. this is my ip route for wired connection CODE scorps@scorps-laptop:~$ ip route get 1.2.3.4 1.2.3.4 via 10.0.0.2 dev eth0 src 10.0.0.10 cache mtu 1500 advmss 1460 hoplimit 64 scorps@scorps-laptop:~$ for wifi connection CODE scorps@scorps-laptop:~$ ip route get 1.2.3.4 1.2.3.4 via 10.0.0.1 dev wlan0 src 10.0.0.21 cache mtu 1500 advmss 1460 hoplimit 64 scorps@scorps-laptop:~$ Added on August 21, 2008, 1:00 amthis is my network setting,, adsl modem --->>wifi router (as switch, disable security,)>> users | | as pppoe mode gateway for modem : 10.0.0.2 gateway for router : 10.0.0.1 what else yeah?? all in dhcp mode... if connect direct to modem using wired,it's working great but if connect to wifi router using onboard wifi, that's problem happen  after i edit it, it will revert back according to gateway number of modem and router...

Is there by any chance you are using both wired and wireless at the same time?
I meant, your wired cable still plugin while trying access using wireless. That will not work.. Like I said before, those automatic tools sometime can cause problem. Let's do the old skool. Test first: Disable automatic tool (some call zeroconfig) usually some avahi module, resolvconfig and network-manager. From you screenshot, it's network-manager. Kill all this services: 1. killall -9 dhcdbd 2. killall -9 NetworkManager 3. killall -9 NetworkManagerDispatcher Edit /etc/resolv.conf : CODE nameserver 202.188.0.133 nameserver 202.188.1.5 Now edit your /etc/network/interfaces so it will look like this: In this example, we disable the wired network so it will not clash with wireless. Test 1 1. Dynamic ip CODE auto lo wlan0 iface lo inet loopback iface wlan0 inet dhcp Restart network: /etc/init.d/networking restart Test 2 2. Static ip CODE auto lo wlan0 iface lo inet loopback iface wlan0 inet static address 10.0.0.21 netmask 255.255.255.0 network 10.0.0.0 broadcast 10.0.0.255 gateway 10.0.0.1 Restart networking: /etc/init.d/networking restart Check ifconfig to see wlan0 get ip. See if you can connect to internet. If the above works, you better off without network-manager. Remove/uninstall network-manager and dhcdbd. So does resolvconfig.

You need to edit using root or sudo in Ubuntu. sudo gedit /etc/network/interfaces |

Have you check what is inside /etc/resolv.conf after restarting networking?
It should be ok with the static ip setup. Using static ip setup, run this as root: sudo echo "nameserver 202.188.0.133" > /etc/resolv.conf Then try ping google. This post has been edited by oshiri: Aug 21 2008, 12:11 PM |

That's wierd.
You should by now be able to ping outside. I'm out of idea. Have you test this in windows? check your modem----wireless router setup Is your modem is pure modem or router with builtin modem? Because router with builtin modem need to change to bridge mode first in order to use wireless router. I think you already know this. If your wireless router using linux, you could telnet into it and do some testing, ping for example. This is how I test in my router: CODE $ telnet 192.168.1.1 Trying 192.168.1.1... Connected to 192.168.1.1. Escape character is '^]'.
