David is having issues with his Wi-Fi upstairs. Leo says that if he's using the router from his ISP's modem, he should turn off Wi-Fi and get his own router. That often will solve the problem. He should make sure he has a DOCSIS 3 modem as well. In fact, while he's at it, he should just buy a modem as well. That way he will save the monthly rental fee he's paying his ISP for that modem.
Steve has his own Wi-Fi router but his cable company just gave him a new router with Wi-Fi built in. Is it more secure? Leo says they're about the same security wise. He'll want to be sure to turn on WPA2 password protection. And often routers have security flaws and rarely get updated. So Steve should make sure he has his router firmware updated.
Ed has the Skybell, a webcam door knock that allows users to see who's at the door from their smartphone via Wi-Fi. But he can't get it to work. Leo says that's because it has to connect via Wi-Fi, and he has to be sure it's connected to his network. He'll also have to have a 2.4 GHz system, and that's the most crowded spectrum because everyone else is on 2.4Ghz. If he can use 5 GHz, that would be better.
Chuck's home based business has grown to the point that he has to move it into his garage. But his Wi-Fi is spotty in there since it's 150 feet away. How can he push the range of his Wi-Fi router? Leo says that Chuck is at the edge of the usable signal range. He'll need a repeater and keep it line of sight from the router. Metal is death to Wi-Fi, as it acts as a Faraday cage. So Chuck should remove any window screens. Leo also recommends using a Wi-Fi analyzer to see what congestion is happening in Chuck's area.
Jeff has a client who's going to be doing a great American roadtrip with RVs and they want to bring all their tech. They need to sync it all, and Jeff wants to know how they can do that while on the road? Leo says that the Airport Express is a Wi-Fi access spot and it will be a router if he plugs it into the internet primarily. Jeff can create an Ad-Hoc network without Internet access as well.
Joe just got a router and wants to know if he really needs firewalls anymore. Leo says no. Joe could turn on the Windows firewall, but any third party firewall isn't really needed because the router is essentially a "dumb box" that prevents attacks from incoming traffic.
Archie has a Wi-Fi router and has connected his Roku, but he's not getting good enough reception and it buffers a lot. Leo says the farther the router is from the Roku, the less connection can be made. But Leo also suspects that the router isn't giving Archie as much bandwidth as he needs. It could be due to congestion.
If his router supports the 5 GHz band, it's a much better choice for streaming. He can also take the old router and put it in bridge mode and use it as a repeater to pass along the signal.
Noah has a Dell Inspiron 17R laptop but he's having trouble connecting through his new Motorola router. It's slower than anything else. Leo says that the Inspiron's 17R Wi-Fi is G/N, and if he puts a device on it that uses a lower Wi-Fi standard, it downgrades everything to that lower standard. Also, Windows Machines slow down over time, so he may need to start over and restore to factory conditions to speed up the performance. Leo says to try connecting the laptop to the router via ethernet and see if it speeds up. If it does, then it's a wireless problem.
Greg finished installing his home theater system and he wants to know what device is good for watching movies on his computer. Leo says that Plex is great on the Playstation or Xbox, or even the Roku or Fire TV. It connects to the media storage, such as a networked desktop. Leo likes it because it's simple. A Mac Mini would work great, and it's small. It has HDMI out so it'll plug right into his AV receiver.
Avis is remodeling her home and she wants to wire her home for three computers, security cameras, and her home theater. Leo says that will require a high speed connection with all that video data. It's hard to future proof, but as long as she has the walls open, she should put conduit in. That way, when she needs to upgrade, it's a lot easier to run new cable through it.
