Dave wants to know how to find out how much bandwidth he uses every month. Leo says that if your router supports DD-WRT firmware, you can. But your router may already keep track. So look in your router settings to find out. If not, and your router supports it, you can install DD-WRT firmware. Check out dd-wrt.com. But understand, that flashing the firmware on your router could void the warranty. If you need a new one, get the ASUS router, it uses a flavor of DD-WRT already out of the box.
Neil is worried that the VPN Filter hack will affect his Asus router because his model isn't protected. Should he be worried? Leo says first thing he can do is update his firmware. Asus keeps their firmware up to date regularly and uses open source DD-WRT firmware. So if there isn't one, he can patch it himself. But Asus routers are great because they update them constantly. Neil should reload the most current firmware, even if he has already updated it. That will wipe out any additional problems.
Jeff wants to know why his internet slows down at night. Leo says that he ends up sharing bandwidth with his neighborhood and if it's slowing down in the evening, it's because everyone is on Netflix. He also has to factor in Wi-Fi congestion. Jeff could bypass the Wi-Fi router and plug directly into the modem and see if it speeds up. If it does, then he'll know it's Wi-Fi congestion. If not, then he'll know it's his because of heavy use in the neighborhood.
