Alan is having issues with his wireless routers since a power surge, especially on the 2.4 GHz band. Leo says that's because 2.4 GHz is overcrowded. Everything seems to use it. That's why having a dual band router is beneficial. It could also be that the power surge fried his 2.4 GHz band. Routers also wear out, and over time, it starts getting slower and more unreliable. It's probably time to get a new router.
