Laurie is frustrated with her DSL because it's constantly dropping off. Leo says that DSL often comes on old copper wiring and the farther away you are, the more likely you'll get drop offs. The inside wiring may also be an issue. Laurie's provider also has an inside wire plan she can pay for, but it sounds like Laurie is pushing the edge of her existing technological capabilities. And since they're pushing Laurie to go FiOS, they have little motivation to fix the old lines. But FIOS uses Fiber Optics and it's more reliable and faster. It can also be more expensive, though.
