San Juan del Sur, Nicaragua is spectacular. For something a little more remote, Cahuita, Costa Rica is great too and is not far from the surfing mecca of Puerto Viejo. I bet you can find wifi in either spot, at least in San Juan del Sur and Puerto Viejo. There's some beautiful spots in the Philippines as well. Try El Nido or Dumaguete (great diving and both definitely have wifi).
