Have a look at your interface setup. The commands ifconfig and route might 
give you a hint what is wrong. The relevant output lines of ifconfig 
should look like this:

eth0      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:192.168.2.xxx  Bcast:192.168.2.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

Please check that the inet addr is 192.168.2.xxx with only the xxx being 
variable. And the "UP" part is important too.

The output of the route command should look like this:

Kernel IP routing table
Destination   Gateway       Genmask         Flags Metric Ref    Use Iface
192.168.2.0   *             255.255.255.0   U     0      0        0 eth0
default       192.168.2.1   0.0.0.0         UG    0      0        0 eth0

If you post any differences, we can probably find out what's wrong.
