Do you have a default route setup? What does
netstat -rn
show?

If theres no default route, try this:

route add default gw 192.168.1.1

then try to ping something. It's always best to ping before trying a
web page to see if you have basic connectivity. And if possible, try it
by numbers if you know some IP addresses (although these can change)

Eg. at present, www.linx.net is 195.66.232.45

If you can ping that by number but not name, then you have a DNS problem.
Try putting

nameserver 192.168.1.1

into /etc/resolv.conf.

DHCP usually does all this for you which is why it's so popular! If you've no
real reason to not use it, then just turn it on on the Linux box.

But if you are going to stick with a static IP address, make sure it's not
in the range allocated by the router! Some routes just DHCP the
whole subnet (eg. from .2 to .254) and if it were to allocate .55 to a
different PC then you'll have all sorts of fun and games..
