Hi

Simple minded approach -- I'm sure others will have better.

On the machine that's having the problem (when it's having it), execute from
the command line:

route add default <ipaddress of your gateway>

The only time I've ever seen this is when I had that messed up, but I've never
used ppp either. If that clears it up, a little local customization is called
for. If not, hope there's other, better answers in the offing.
