You have to get a lot of watts on the first route and when you're taking your Pokemon out of the Pokewalker, it should say on the top screen how many watts till next route. When you get watts on the Pokewalker, don't use them all.
Resetting the Pokewalker doesn't affect Routes; they are stored on your cart.
