Thanks fo all the help, however this is not working i have tryed the commands:

Quote:
smith@smith-laptop:~$ sudo iwconfig eth1 essid "linksys_OW_45452"
[sudo] password for smith:
smith@smith-laptop:~$ sudo ifconfig eth1 192.168.0.51 netmask 255.255.255.0 up
smith@smith-laptop:~$ sudo route add default gw 192.168.0.2


smith@smith-laptop:~$ sudo iwconfig eth1 essid "linksys_OW_45452"
smith@smith-laptop:~$ sudo ifconfig eth1 192.168.0.51 netmask 255.255.255.0 up
smith@smith-laptop:~$ sudo route add default gw 192.168.0.1
smith@smith-laptop:~$
But still can not connect to any of these sites http://192.168.0.1,http://75.126.162.205 and www.linuxquestions.org

I guess it is time to step back and start over? all the information that i have given you is all that i know as far as the router, IP address etc.

I have used the commands that you requested, sometimes spelling was a problem, but it just is not working, it is getting worse. I am going to try to reinstall the Ubuntu once again to see if it corrects its self.

thanks for the time and hope to connect soon.

LN;
I asked you several times for complete answers, I asked for specific tests, and I asked for a summary in which you address ALL of the suggestions and questions to date.

I do not understand why you do not want to do the tests I requested--and why you will not respond to several specific questions. But, that is your choice.

Your best bet at this point might be to find a local expert to sit with you and work through this---I would start with a local Linux user group.

The way I read the problem, re-installing Ubuntu is not going to help.

Good Luck

What did you do to test the connection between the configuration steps?

I've stayed out of this since my first post to this thread. I think you need to concentrate on getting one connection.

Look at 'Missing your Wireless Drivers?' to get the driver functional without the hassle of device assignments/changes.

You could use the 'The Broadcom Firmware (tar.gz)' file from the above sight. Once you have the proper firmware installed then the operation will fall into place without to much effort.

I've got a 'BCM4312' which required me to jump through hoops. I went with the 'STA' drivers & patches but found the driver/firmware to be a problem at times. I tried to revert to older firmware but could not get the right one. BY chance I found this older driver that will work with my version of the 'BCM4312'. Sure, you will get warning error at boot that the driver maybe to old but it will work. The switching of the device to the 'eth1' device has caused me some reliability and recognition problems. If you use the referred driver then the 'wlan0' device will be recognized.

BTW, to reinstall your OS may/maynot remedy the problem. As I said earlier, break the problem down to working on ONE issue at a time.

Look at 'How to Ask Questions the Smart Way'.

Just a few links to aid you to understand what your doing;

Linux Documentation Project
Rute Tutorial & Exposition
Linux Command Guide
Utimate Linux Newbie Guide
LinuxSelfHelp
Getting Started with Linux
Advanced Bash-Scripting Guide

Those were 2 tests. You should have done 1 test, test the pages I indicated and THEN do the second test. I'm trying to get information from your environment. I don't know the ip address of your router and I was trying to guess it was either 192.168.0.1 OR 192.168.0.2. I still don't know because you mixed up the two tests. Please do them in order and report what you find step after step. Indeed, it is not ideal to work like that, it would be best if you could provide information from windows, like asked by pixellany. But from what I understand, your Windows machine is connected to the internet by a wire and we don't know if it is connected to the same router you are trying to connect to with your Ubuntu machine. Reinstalling Ubuntu won't help I'm afraid. You still need a way to talk to a router you know nothing about. With luck we can find how to connect to it, but it would be best if you could ask the router administrator to assign an ip address to you or to activate the DHCP server on that router.

onebuck;

What you may have missed is that---at one point---he had a connection. Thus, drivers don't appear to be the issue.

This is why I have requested a synopsis which lists the answers ALL questions brought up in the thread.

hi, a few days ago they were able to ping internally (and possibly externally):
http://www.linuxquestions.org/questi...03#post3840103

how do we get them back to this point ?

At that time, there was a DHCP offered by machine 192.168.0.1 (as you can see in the post you linked to).
But as you can see in post #52, we don't have any DHCP server responding on eth1 (connected on the linksys via wifi) anymore. I suspect there was another machine connected to the router that had a DHCP server and now this machine is off. I suspect the router doesn't offer DHCP. It looks like the router is on network 192.168.0/24 because the machines that acted as DHCP server were 192.168.0.1 and later 192.168.0.2. He pinged both machine in post #30. I don't know the ip address of the router, maybe it is one of those two machines?

We don't have DHCP anymore, so we have to guess the correct ip to set the machine to and the ip of the router to connect to. I don't know how this network is set up, but there are several machines, or the router administrator likes to change the settings without notice.

LN Smith needs to find a machine that is connected to that linksys or an administrator and tell us what is the ip address of the router, or we can use nmap and try every single machine until we find the router. I think his patience is running low though, so the last option will be difficult, especially since he doesn't like the command line much. He doesn't seem to be able to tell us which machines are connected to the router and he doesn't seem to have any contact with any administrator either. I don't know what is the best plan from there. What do you think?

^ are we sure the route command didnt mess with their ability to dhcp (admittedly, i dont know much about the route command).

i think they mentioned that their ipod works on the network. is it possible to see what the network parameters are on the ipod - i dont have one so i dont know how to get to that menu.

Ok not giving up just yet! this is what i know so far: This problem with the wireless connection and the Ubuntu system started when i got disconnected, a wireless connection, during a download upgrade, after I was first connected to the internet. I have been trying to install everything from a USB stick back onto the Mini sense then. Everything is working fine except for the internet connection and the NetworkManager, all other information seams to be fine.

the wireless drivers to my knolege are installed and working. they were BCM4312 and i am now using STA drivers. the iwconfig is:
Quote:
smith@smith-laptop:~$ sudo iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

When trying to connect using the wireless connection all the settings are set to automatic. that is what they were set at when i got connected the first time.
when i tried to connect with the LAN connection on our network this is what the settings were set at, and i did not turn on my desktop to run at the same time.:
IP address 10.1.1.60
SubnetMask 255.255.255.0
Default Gateway 10.1.1.254
DNS 10.1.1.100
10.1.1.101
Metric Automatic.

Again I would like to thank all of you for your Help and support.

hi ln, i share you frustration...
if i understand you correctly your wired lan gives ip's like 10.1.1.x
but your wireless lan gives ip's like 192.168.1.x

so either the router uses class a hierarchy for wired and class c for wireless (i dont know if that is possible).
or your workplace has 2 different routers (1 for wired/ 1 for wireless).

or it is possible that the dhclient program is screwed up because it is no longer getting an ip address from your router (you were before - maybe in the last 2 days someone changed it so that people have to be set up by an admin for security reasons -- does your ipod still work on that network ?).

this is starting to get wierd.

maybe tethering your fone would help you get internet access (but i dont know how to do that).

You have the kind of positive attitude I like.
Maybe your desktop is using some kind of vpn virtual interface? Do you have any device that can connect to your wireless router currently?
Do you know how many machines are connected to the router? Maybe the maximum has been reached and he does not accept any other host?
I don't expect it to work, but could you please try to connect like that:
Code:
sudo iwconfig eth1 ap 00:18:39:72:9C:23
sudo dhclient eth1
(please post the output of the commands)
then post the output of
Code:
ifconfig eth1

Yes all i was given by the IP person was to use the setting :
IP address 10.1.1.(and any range 60 to 69 hear)
Subnet Mask 255.255.255.0
DNS 10.1.1.254
and then they said i would be connected! there are Two people hear today with Ipod's that aru using the router and they are connected just fine.

using this code I get:

i dont know but maybe this will work:
Code:
sudo iwconfig eth1 essid "linksys_OW_45452"
sudo /sbin/ifconfig eth1 10.1.1.65 netmask 255.255.255.0 broadcast 10.1.1.255
sudo cp /etc/resolv.conf /etc/resolv.bak
sudo echo "nameserver 10.1.1.254" >> /etc/resolv.conf
^ can somebody tell me if this looks correct ?

then try to ping stuff like 10.1.1.1, 10.1.1.254, 75.126.162.205, www.linuxquestions.org
