Networking :: why when set static ip cannot ping?

Why when static ip is set to the machine using ifconfig, cannot ping the other machine? The network card that i am using are build in and confirm connected and able to ping before using DSL. Could anyone out there provide any guide why my machine cannot ping and solution?

That's not really enough information for someone to help you, but let me try anyways.

How did you set your static ip with ifconfig? Did you do something similar to the following...

ifconfig -v eth0 192.168.1.100
route add default gw 192.168.1.1

Did you set your machines ip to an acceptable range that will match the rest of your network? Does your netmask match the networks? Did you specify the correct gateway? Can you ping google.com? How about 216.239.39.99? What about your own ip (not the loopback, the other one)?

Using what OS? Was it Linux? Was it Windows? Does DSL even recognize the card? Have you tried

Code Sample

dmesg | grep eth0

to see if the kernel barked about your ethernet on boot?

I need a little bit more information, but I would guess one of three things happened...
1.) You've incorrectly configured your ethernet card
2.) The driver your ethernet card requires isn't built into the kernel that comes with DSL
3.) your resolv.conf needs tweaking

I'd try dmesg first to see if the kernel barked at your ethernet card, then I'd make sure that all of the settings you've specified in ifconfig is correct and as a last ditch effort append

Code Sample

nameserver 4.2.2.1
nameserver 4.2.2.2

to /etc/resolv.conf

Hope this helps.
