Wi-Fi routers, home servers, virtual private networks, and more.
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.
Glen has a Windows 10 laptop and he likes to turn it into a Wi-Fi hotspot. But when he leaves for awhile and comes back, he can't reconnect. He has to retype the commands and change the access name. Leo says that Glen is using an adhoc network. Leo says he can do it in the Control Panel easier. That could create a more lasting connection.
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.
Harry is reinstalling the Windows Vista OS on a friend's computer and now it's connected to "an unidentified" router with a local access only. He can't get online. Leo advises connecting via hardwire. If that works, then it's a setting that's not allowing it to get online. A driver may need to be downloaded as well. Getting the motherboard drivers from the manufacturer could solve it.
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).
Larry is thinking of going with powerline networking in his house. Leo says that thanks to the Powerline Alliance, powerline networking has gotten a lot better in the last few years. It's not as fast as Ethernet, however -- it's about half the speed. But it's still pretty good. Leo does it for his house and it works great. But instead of 20MB throughput, he'll get half that.
Eric gets Wi-Fi where he lives but it's very weak. Would a repeater help? Leo said it could, but he'll need to place it half way between the router and his location, and that may not work well for his living situation. A USB Wi-Fi antenna could be a better choice because he can position and direct it.
