Freebsd 8.1 can not access internet. HELP

HI folks,

I just install Freebsd 8.1 release from CD and install the base
only, I configure my RL0 network card and ip address and other
require info by using sysinstall command, then test ping
ping the host freebsd and it assigned ip and seem to work
find, but I can not ping other computer or router and can
not access the internet to install other package.
Is freebsd 8.1 change anything or I miss anything else
that require before it can ping other computer in the
network and access the internet? Freebsd 7.1 was smooth,
I just configure network card and ready to access the internet
right away. But not able to do it the same with 8.1

Thanks for the help folks

I just found out that I plug in the build network feature
on the motherboard that I already disable that why I can
only pit freebsd host but other computer or out on internet.
This is resolve.

NEW PROBLEM:

After install Xorg through SYSINSTALL, I test
the configuration using Xorg -configure and
test the new config file, the system encounter
keyboard issue. here is the output:

/usr/local/bin/xkbcomp: not found
(EE) Error compiling keymap (server-0)
(EE) XKB: Couldn't compile keymap
XKB: Fail to compile keymap
Keyboard initialization failed. THis could be a missing or incorrect
setup of xkeyboard-config

Any clue how I can fix this?

Thanks
