As you rightly point out, the gateway is not located on the same subnet
as your IP address.  In effect this means that you cannot communicate to
any host beyond your own subnet.

I'd called this IP setup 'broken'!

It sounds like either your IP address is set incorrectly, or
alternatively that your gateway address is set incorrectly.

In order to fix this, you need either:

- a different IP address, falling in the same subnet as your quoted
  gateway address, or

- a corrected gateway address which shares the same subnet as your
  quoted IP address.

If you're on a corporate or academic network, I'd speak to your local
network admin to figure out what the correct settings should be, because
the settings you give above will not work on *any* OS (assuming the
information you've provided is accurate and complete).
