Weird. So we have:

ping neo->local		almost always fails
ping local->neo		works
ping neo->remote	almost always fails
httping neo->remote	often fails
ssh local->neo		works
dns neo->remote		works

And all the troubles vanish if you  wmiconfig -i eth0 --power maxperf
Is this correct ? Did you try any other combinations ?

I suppose the other systems on your network never have such problems ?

This is consistent with a lossy but otherwise unremarkable connection.
So no corrupt packets or such.
