How to connect internet across a static IP network?

Question

I'm using Ubuntu 10.04 but without internet at home.
The reason I think is I have changed my network connections recently to static IP from DHCP because gnuradio needs static IP for accessing external hardware.
Since then it works in college and I can't access internet at home.

My ifconfig eth0 result comes like below:

eth0      Link encap:Ethernet  HWaddr f0:4d:a2:86:5f:0c  
          inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:28 Base address:0xa000 

My cat /etc/network/interfaces output comes like this:

auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

How can I make it work at home with static IP?

Answer 1

It is possible that your home internet does not use 192.168.1.*. You could change the configuration on your router to use 192.168.1.* addresses. You should check the user manual for your router to learn how to do this.
