Asked by George Francis

I HAD a computer in one room with XP. One in another room with Me. I installed Ubuntu 8.04 in the computer with XP. Now I cannot access the internet from the Me computer.

This is probably because the "Me-computer" wasn't directly connected to your router or cable modem. Do you have a switch or hub connected in between? Best practive is to connect both computers to that switch and the switch tself to your router or modem (assumed it has an uplink port).

A map could be like that:

ROUTER (IP: 102.168.0.1) ---> SWITCH ---> Computer #1 (IP: 192.168.0.10 | GATEWAY: 192.168.0.1) & Computer #2 (IP: 192.168.0.11 | GATEWAY: 192.168.0.1)

All masks are set to 255.255.255.0 and DNS optionally to 192.168.0.1 if required.

It's also wise to check your computers desktop filters (firewalls) and the firewall settings within your router (does not apply to a cable modem).

Previous to the installation, how do you connect to Internet? Using a router or using a shared connection trough the XP computer?
Can you post the IP configuration of both computers?

That may be the problem but I do not know what to do about it. Evidently , somehow I must have formatted this drive and lost XP and now only have Ubuntu in the HD. I do not know how to find XP if it still exists in the drive. George

Hi George, did you try pressing <Esc> while the system is booting up (Grub), there you can choose the OS on which start.
Another way to see if something else is installed on your computer is go to Places->Computer and see how many volumes appear.
Also can you open a console and type:
 fdisk -l
and press <Enter> and then post the output here (This command tell us how many partitions and their type do you have).
Hope this helps, let me know.

Hi Ariel: Thanks for that information. I am pretty clumsy with Linux
commands and need almost step by step instruction. I will need some
time to implement your suggestions. Many thanks. George

Ariel: Using a router ,Linksys, wired.....not wireless. I am not sure
how to find the IP configuration.....? I cannot access anything that
was on my XP operating system before I put Ubuntu in. My XP goes right
into Ubuntu loading on power up. George

No problem George, take your time.
First, do you know how to open a terminal? if not, go to Applications->Accessories->Terminal.
When opened, at the prompt, you must type:
 fdisk -l
and press <Enter>
This will produce an output that you can copy and paste here.
Can you do that? If you need more detail, just tell me.
Hope this helps, let me know.

I'm trying to be helpful, don't need to shout, can you explain me what part you cannot do it?
Can you open the Terminal? or your Ubuntu doesn't start?
When Ubuntu starts you see two bars (one on top and one on bottom of the screen), in the top bar you must see the word Applications (make a click on it), then, when a menu appear select Accessories and then select Terminal.
I need some info from you just to help you to solve your problem.

Ariel: Oh, my. I was not shouting......rather emphasizing how useful
your suggestion was. The caps is my way of expressing pleasure in
receiving that information. I am most sorry that you thought
otherwise. Yes, I can do what you have suggested with the terminal and
will do it soon. Right now, I am collecting my thoughts.....printing
your suggestions so I don't forget, etc. I am an old man.....have three
college degrees, not boasting, but never had even one lesson in Linux.
Up until you gave me encouragement by responding, I was about to format
the HD , re=install XP and start all over altho I would be most unhappy
having lost data that might still be there. Anyway, my sincere thanks
and apology for my mis=use of capitals. George

Hi George, no problem, all ok with you.
I'm also not a kid (near 50) and I only have two college degrees (math and electronics), feel free to do what you want but if you ask for help, please answer our question to let us help you (even if you don't understand for what).
We are not seeing your computer, in this scenario, you are our eyes and ears and if you are blind and deaf (or if you cover your eyes and ears), we (you included) are in serious troubles, we can do almost nothing to help you.
With my best regards. Ariel.

Thanks, Ariel, you have been most helpful and I am most appreciative. I
am hoping that my stupidity in installing Linux (not paying close
attention to instructions) has not resulted in total loss of data stored
in XL. I will learn more when I use the terminal and the fdisk command
I am sure. Kindest regards, George

Made several tries. George.

The fdisk must be run as superuser so please type:

sudo fdisk -l

give your user password if requested, you don't see nothing when you type it, then press enter.

Hope this helps

Hi Marcobra: Here is the info from ifconfig .
I do not know if I can get the ip info from Me since I cannot E-mail
from that computer. Otherwise, how can I get this information? Thanks,

Hi George:
Can you take note and tell us the values of IP address, the Gateway, the Network Mask, the Primary DNS and the Secondary DNS in their network configuration (Control Panel->Network if I remember well WinMe but not sure).
Hope this helps, let me know.

Unfortunately I do not have the powers to change the state of this question to SOLVED, EXPIRED or INVALID. Someone here at Launchpad either grant me that permission or simply apply the change in state to this question, please.

Can you help with this problem?
