Wi-Fi routers, home servers, virtual private networks, and more.
Susan is having trouble streaming with her Blu-ray player and her TV. Leo says it could be that the Blu-ray's Wi-Fi isn't working too well. She may need to move her hotspot closer to the TV itself. It may also be that there's congestion on the 2.4 Ghz band, and her TV won't pick up the 5.0 Ghz band. She should try using her mobile phone as a hotspot and see if it picks it up. If it does, then the Wi-Fi spot is either too far away or is congested and swamped by other signals.
What's going on with AirPort development? Leo says that Apple has reassigned most of the engineers who handle the Airport to other products, so it sounds like Apple is moving away from it. Since routers do wear out and become unreliable over time, it's probably time to replace it with a different brand.
Gloria wants to cut her phone service and use Ooma. Is that a good idea? Leo says that with one computer plugged into the internet, she can, but she'll also need a router so she can give access to others. A simple wireless router from Asus or DLink would work well. She should go for the dual band or tri band router. The WireCutter suggests the TP-Link Archer C7 (v2). She can find out more about it at thewirecutter.com.
John downloaded a VPN program called Jailbreak and now his Windows 7 machine can't connect to the internet. Leo says the VPN is probably at fault here. VPNs act as a go-between between him and the servers he surfs to.
Kirk created an administrator password and has forgotten it. Leo says that if he created it with his Microsoft account, he can recover it. But if he didn't, then there are ways to crack a Windows 10 login. He can use OphCrack or ConBoot to get around it. Here's a few articles to can show him how:
Wikileaks has announced Vault 7, a massive collection of documents that show how the CIA uses malware and other hacking techniques to spy online. Some of the techniques includes using smartTVs as a spying device since they use cameras and microphones built into the TVs. Samsung warned of this in their terms of service for their TVs last year. But Leo says that the CIA doesn't really have a switch to turn on all TVs, and if they did, the data they'd receive would be so massive and 99.9% of it would be useless. It could be used for targeted eavesdropping, though.
Marcello has noticed since Spectrum bought TIme Warner, he has trouble connecting to the internet. They disconnected his router and it works, though. What happened? Leo says that when Spectrum took over, they probably enabled the router side of his modem and that put it in conflict with his router.
Brad says every time he tries to upload his photos to Google Photos, his Wi-Fi fails. Leo says that turning his Wi-Fi off and on could help as it renews the "lease" on the router with a new IP address. Something inside the Mac's network settings could be messed up, and renewing the lease can fix it.
It could also mean that the computer has lost contact with the router. He should reset his AirPort and update the firmware. That chatroom says it may be Google Photos that's causing the issue as well.
Anne Marie and her husband have an internet TV channel called The Holy Spirit Broadcasting Network. Leo says it's great that they're harnessing the distribution power of the internet to reach the world. That's the democratization of the internet: it makes content available to anyone and everyone. Anne Marie wants to know if she should have a Roku app made so that people can stream to their TV. Leo says she'll have to be careful with who she has write the app.
Mike is thinking of putting cable inside his house, but he's not sure what to wire it with. Leo recommends going the extra step and putting conduit in. That way he can rewire the house when the technology advances without yanking out the drywall again. These days, he'll want at least Cat6, maybe 6a for now. He shouldn't go for fiber now, though. It's pretty expensive.
