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.
Pedro created an account at OpenDNS but it isn't working for him. Leo says that OpenDNS can protect kids with a custom "phone book" that has a list of approved domain names in it. OpenDNS can then filter out the undesired addresses that he wouldn't want. If he inputs the router server settings of OpenDNS properly, it'll filter the traffic correctly. But if his kids have figured out how to change the settings in the computer, it can override that, unless he's made the settings in the router itself.
Frank is having trouble installing his Nest Cam. It won't work unless he turns off his firewall. Leo says that's not good. But it's the nature of a firewall, as it blocks a conversation between incoming and outgoing traffic. That's why Leo recommends using a router instead. He can also use the DMZ feature, where he could allow the Nest Cam to bypass protection. Leo doesn't recommend it, but it can be one option.
Cam has an Arris Wi-Fi router hardwired into his computer, but he can't modify the settings. Leo says he should be able to. He should call the cable company and ask them for the password to access the router. Or, instead of using their router, ask them what third party routers they will support and he can buy his own. He'll want a DOCSIS III.
Check out this app: Snoop Snitch in the Google Play store. It will tell him how secure his router is.
William has an Airport Extreme router that disconnects 3-4 times a day. Leo says that's not unusual with routers. They're basically just a dumb computer that sometimes crashes. So he'll have to unplug and reboot it. If it continues after that, it indicates that the router is starting to fail and he'll need to replace it. He can also try rebooting his modem.
Peter's parents have AT&T DSL and it's terrible. Leo says that's because DSL is reliant on the phone lines, and the farther it is from the central hub, the more problematic it can be. If the phone lines are antiquated, that's even worse. He can demand that AT&T upgrade its wires, but then he's really dependent on their good measure. One thing he can do is turn off the Wi-Fi capabilities of the router they gave him and connect his own router. That's likely going to speed up the wireless speed tremendously. Leo like Asus routers.
Dale needs to buy a router for a complex computer network. What's a good one to buy? Leo says that he uses an Asus AC3200. It's very good and very configurable. A good way to extend a wireless network, though, is to use WDS with the prime router and then a wireless extender/repeater about midway. It's always good to use the same brand. But congestion can kill bandwidth.
Tom has a TP-Link powerline adapter and he needs to plug it into his router, but his router is full. Leo recommends getting a hub that will attach to the router and give him more ports. TPLink even makes one. He'll just need to free one up and then plug this in and he'll have several more ports to plug into.
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).
