thank you for your answer. first,I use the dhcp to get ip address; seond, the resovl.conf now is: nameserver 192.168.2.1// this is ip of
router search localhost It is a great idea to use another profile for
home.I will try. But I was still puzzled.which part the route changed
except the resolv.conf? could you give me a list of setting file of
this problem? thank you!

Are you using DHCP to set the IP address of the Linux box?
What does "cat /etc/resolv.conf" give for an output?
Is the problem that you can not reach the Internet at all, or that you can only reach sites if you use the IP address instead of the name? (If you do not know how to do this, the answer to the question above may tell us.)
If you are using DHCP to set the IP address, then Linux will change the route, and the name servers based on the information it gets from the DHCP server. (Probably the router.) It should change again when connecting to a different network. But it is possible that one network provides more information then the other, and so not everything changed back the way it should. (Net Profiles can help here - you can have one profile for home, and one for work.)

Well, with DHCP the routes are not stored in any file. Instead the routing information is created from the information recieved. The only information that is actualy put in a file is the name server information. That is what is in /etc/resolv.conf. If that information is wrong, then the computer can not find the IP address that goes with a domain name.
In this case, it looks like your router is set to act as a name server
for your local network. You can check if this is working by running "dig linux.org" and seeing what information you get back. If it gives you an IP address, then that is working fine. If it gives you an error, then the error message will help determin the problem.
ALso, if you would run "route -n", that will help also. You should be able to use DHCP at both locations without problems. One other thing that may be causing you problems are proxy settings. You probably don't use any at home, but if you do at work, then your web browser may be trying to use the proxy at work, and that will not work.
