Dennis is going to be RVing full time and wants to know the best way to stay connected. Leo says that he can get a satellite add-on to his RV and many come with it built-in. He'll always have to aim it where he goes, though.
Betty can't log into the internet with her Mac. It says there are no plugins to do so. Leo says to check your router connection to see if your WiFi router is turned on. You can do that in the Apple's Network system preferences. If you can't see your access point, you're not connected to it. If it's connected, then look if the internet connection is available. If the WiFi router isn't working properly, it'll be connected, but it won't go anywhere. It'll just be a local address starting with 168. Try resetting your router.
David's landlady has wifi but she doesn't want to improve the signal so he can get a better connection. Leo says you can get a WiFi antenna to improve your signal,but if you can convince your landlady to put the access point in a better location, that would be the ticket. Check out RadioLabs.com for tips on which directional antenna to buy to get a better signal. You could also offer to buy her a newer 802.11 AC router. Leo likes the Asus C3200. It goes a long way.
Jim's church has an auxiliary building that's about 300 feet away and they'd like to create a connection in order to broadcast the church service when they need overflow seating. Leo says he can create a directional Wi-Fi setup that will beam the service directly to the building without the need to deploy cable. He should check out this article at RadioLabs.com. It won't cost any more than running an HDMI cable.
James needs to set up Wi-Fi restrictions on his router. Leo says that it's very router specific, and he can go into his router settings and leave it open by MAC address. He can also schedule internet access. James will need a router that supports Access Control Lists (ACL).
Dave just bought an RV and he's looking for a booster for Wi-Fi and 4G Internet reception. Leo says truckers use Wi-Fi antennas and many have magnets. As for 4G, Leo says he won't really need one for that. It either works or it doesn't. And in areas of limited reception, the chatroom says that Weboost makes them for $200. It's essentially a 4G repeater.
Robert wants to extend his Wi-Fi range. What should he get? Leo says a repeater or extender will help. He'll just put it midway between where he wants to go and where his router is. That will usually work. But if he has issues with the signal getting blocked, he could try powerline networking.
Gloria has a Roku Stick and she's been told she needs a router to use it. Leo says that yes, she'll need wireless internet access. If her router doesn't have Wi-Fi built-in, then her choices are to either get a regular Roku and plug it into her modem via an ethernet cable, or buy a router which will handle wireless traffic from the Roku stick. It'll also allow her to connect to her laptop wirelessly. Leo says that if she calls her cable provider, they'll replace her modem with a Wi-Fi modem/router. They'll set it all up.
Gary has a Dell Inspiron computer running Windows 8 and it keeps dropping its internet connection. Leo says he's been having the same issues with one of his XPS 13 machines. Leo says that there is a function key that will turn off the wireless and if he accidentally hits it, he can disable it. But it's also an ongoing issue with Dell.
Ed is building a house in a remote area. Should he install Cat 5e or Cat 6 cable? Leo says that the faster it is, the more expensive it is. It's about 30% faster with each level. So Leo says to future proof your home, buy the 5e, but he should put in conduit so he can replace it with faster cables down the line. It won't speed up internet access, it'll just speed delivery of data within the house. Most people will just be using Wi-Fi, though.
