wired network does not work at home, (Ubuntu 10.04); works in office as well as works in dual booting Windows 7 everywhere.

We need the make and model of the system and the Ethernet chip. WhatWindows does or doesn't do is of near zero value.

Can you give the output of:

sudo lshw -C network; lsb_release -a; uname -a; sudo dmidecode -t 1

Thanks

The output here is obtained in my office where the wired network is working:
rohit@rohitCIO:~$ sudo lshw -C network; lsb_release -a; uname -a; sudo
dmidecode -t 1

When you connect at home, run:

ping -c 4 8.8.8.8

Does it ping ok?

From Home can you run the following please

ifconfig

Copy the output to a memory stick then when you have access to the internet (from the office) post the results back here together with the answer to Andrews question

Here is the output of the two command:

I am slightly surprised by the Internet address.

It is not always the case but 10.0.x.x addresses are not common in home networks. Most home routers use the 192.168.x.x range.
So my initial thoughts are how is the IP address configured and is it appropriate to your home network. The other option is that your home network is fine but the connection to the internet is broken. Can you give us the output of the following please?

cat /etc/network/interfaces; route -n

I am on Windows at the moment, by home I meant a hotel. I have no idea how
the network is configured. I shall obtain the output once I am back in
Ubuntu and send it after getting back on the network.

The problem is that your computer is configured to have a fixed IP address and that address is not the correct one for your home network.

Check with the IT at work if there is anyway you can use DHCP at work. Most networks are configured that way so I would surprised if you can't. If you can the answer is simple we just need to configure your PC to use DHCP everywhere which we can do by editing the file '/etc/network/interfaces'.

If not then we need to set up different settings for each location.

Once you have spoken to your IT department We can advise on how to make the modifications.

Then you are using a static at your company LAN and is not the subnet of your home network. I suggest you change the subnet of your home LAN to be 10.10.10.X just like your work. If you set the system to use DHCP you will probably find you get a 192.168.0.X

You can verify this with your Windows boot

It is weekend in this part of the world. However I suspect DHCP will be
usable at work (can only confirm on Sunday). Please suggest the changes
anyway.
Thanks and regards,

Warren,
  As you suspect the Windows Ipconfig command shows IP address of
192.168.1.110 and gateway 192.168.1.254 Please tell me how to set up DHCP
in UBUNTU.

To check how your network is configured in Windows

Click on the start button type cmd

In the dos box that opens type

ipconfig

On my Win7 machine I see this.

C:\Users\Warren>ipconfig

I suspect the IP address you see when booted in Win7 at home / the Hotel is not comparable with your fixed IP address

Oh you use the wifi in Windows. Are you wanting to use the wifi in Ubuntu?

I see wired connection with address 192.168.1.110 in Windows I suspect
through DHCP. I want to use the same in UBUNTU.
I do not know how to copy paste the DOS command prompt output in Windows
since I usually use Ubuntu.

Open a terminal

gedit cat /etc/network/interfaces

edit the file so it reads

----------------------------------------------------------
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
---------------------------------------------------------

Save and reboot

Ubuntu should now work. You may need to modify this again on Monday If your IT department require a fixed IP.

@actionparsnip. I think you will find the Wifi is not Rohit's but mine I was giving Rohit an example of how to check his IP address with windows.

Hello,
  Writing this from Ubuntu. Problem solved.
   I have anyway saved the fixed ip address version of
/etc/network/interfaces should it be required on Sunday though considering
Windows works there this may not be needed.

Thank You!
regards,
Rohit

Solved.
