Frank was sold on the notion that DSL was always on, but he's had cases where it get drops out quite often. Leo says that by comparison to dial up, DSL is always on. The drop outs are possibly due to being too far away form the central hub, as the farther away, the worse it gets. It could also be a signal that his router is starting to fail.
He should replace his router every few years, and a cheap router is going to go out faster than a more expensive one. He should spent $100 to $200 if he's using Wi-Fi. Leo recommends ASUS or Eero, but that's $500. Leo recommends spending some time at TheWireCutter.com for tips on the best routers with reviews.
