Wi-Fi routers, home servers, virtual private networks, and more.
Gordon cut the cord in favor of streaming through Verizon. After he did that, his streaming speeds plummetted. But it doesn't with his computer. Leo suspects that the issue is due to the WiFi connection to the TV. Most TVs have terrible WiFi radios in them. Leo recommends having a wired connection to television. Use a streaming box, like a ROKU to handle the WiFi and then connect wired to the TV. Another option is to get a MESH Router.
Mike is worried that his WiFi network is compromised since his encryption was bypassed. Leo said that WEP was hacked, and routers went to WPA. And then WPA2. But the latest news is that "Krack attacks" have gotten into WPA2. Leo says it's largely sensationalized headlines and that it's very hard to do and requires a lot of time being on the network itself. Also, by now, most routers have been patched against Krack. So it's not really anything to fret over. And WPA3 is on the horizon, with new routers turning it on with a software upgrade.
Here are some things you can do:
Tony wants to know if guest network accounts safe? Leo says yes, they are. But it greatly depends on how they are implemented. It needs to be sandboxed from the rest of the network so it can't get access to your computer data.
Tim upgraded to the Eero 10 Mesh router and several of his IOT devices don't work. Leo says it works for him: you don't need to do anything but input the new passwords. You don't need to do anything with the SSID. Eero doesn't do anything with choosing different bands. It just works automatically.
Steve wants to install WiFi between two buildings. Leo says that after about 100 feet, the WiFi slows down. He's gotta get a Line of Sight for the access point between the two buildings. Mesh routers would help. Leo suggests looking at the RadioLabs website on WiFi extension.
Dave installed Ubuntu Linux on the HP Stream and now he's having issues with WiFi. Leo says that HP probably didn't make drivers available for Linux, and so the community needs to figure that out. So chances are, there isn't a specific driver for the particular WiFi chip that his Stream uses. Leo recommends trying another version of Linux called POPOS by System 76. It's very similar to Ubuntu, but it has far more drivers available.
Tony has a Synology NAS, but the public folder disappeared from his Windows PC. And Windows won't let him browse to it. Leo says SMB has to be enabled for the folder to be discovered. It's the networking protocol that Windows uses. It will also give you a password challenge. But once you input the password, Windows should remember it.
Chris has everyone set up with WiFi through UVerse DSL, but he wants to move away from it because it keeps going down. Leo says that UVerse DSL really isn't' all that great. It's not like UVerse Fiber. He would like a hardwired system to his Eero. Leo says Eero has beacons to cover the space. Two would be enough (one base, one beacon). The benefit is that Mesh routers have a second back channel to talk between the MESH devices. That makes WIFI much faster.
Todd is getting wireless security video from one building on his property, but not the second. He can ping it, but he can't access it off-site. Leo recommends using a MESH system to extend the signal from building to building.
