Wi-Fi routers, home servers, virtual private networks, and more.
Keith is an IT professional and how he got into the business is through ITDRC.org. It's a group of IT pros who deploy in the event of national disaster. That's a great way to get started and develop serious experience and serve the community at the same time. Leo says that HAMs have been doing that for a century with radio. So it makes sense that computer technology would follow suit.
Tony bought a set of Eero routers, but he's having issues. Leo says that the Eero is a new category of Wi-Fi access point that can create a mesh of Wi-Fi signals all over the house. If it's not working for him, then Leo advises sending it back. It could be defective.

Paul says ever since he upgraded his router, his Mac's NAS doesn't connect. Leo says to drag the NAS out of the Finder side bar, and then remount it. Then he can add it back to his Finder. Paul should also look for "Connect to Server" under the "Go" menu. He can figure out his IP address for the server by browsing to it. It may also mean that the router is blocking it.
Sean is interested in locking down his network completely. Leo says that routers with Unified Threat Management are the best. Sophos is a good one. In fact, Sophos firmware can be installed into many routers that support open source.
Manny's son wants to get into IT, but he's wondering how he could get a job. Leo says that certifications are the diplomas of the IT world. Microsoft and Cisco has CERT programs. He should look at the certs he wants to get and then sign up to get that training. There's even a hacker cert for those who want to work in IT security. Leo suggests ITPro.TV for getting the right training to qualify to test for the certs. Once he gets that first job, then it depends on how good he is at it for getting that second job.
Barbara is on a fixed budget and can't afford to pay for faster internet. She watches a lot of streaming and it buffers a lot, though. David says she can go into her Netflix settings and turn down the resolution settings to SD, which should limit the buffering. She could also watch in off hours.
Richard also wants to know if there's a good satellite internet service. Leo says he can get satellite broadband through WildBlue, but it's not cheap and requires buying special equipment. Another option is LTE cellular service. Often times, it can be even faster than cable. There's also WISP (Wireless Internet Service Providers).
Ray is having trouble streaming. It buffers a lot. Leo says that if his router is a few years old, it could slow down and become less reliable. Rebooting the router will bring it back, but then it'll happen again. So he should get a new one. His TV's Wi-Fi may also be getting "promiscuous," meaning it is jumping to a stronger signal every time it finds one. He can also go into his router and adjust the "lease time for DHCP" to make it longer before it acquires a new IP address. He can also get a dual band router, which will have 2.4 GHz and 5.0 GHz.
David has Airport Extreme routers at home, and he wants to know how much data is being used on his network. Leo says this is one of the drawbacks of the Airport Extreme routers: they lack some of the more modern features that other routers have. One way he could do this is by replacing the Airport Extremes with a more modern router that can monitor bandwidth. Leo uses the Asus AC3200 which has a built-in bandwidth monitor and can even tell him which computer is using the most.
Jay noticed in OS X El Capitan that there's something called "proxies." What is that? Leo says that unless he's using a proxy server, he should ignore it. If it has been set and he didn't know it, it could be a security software thing. Or perhaps a VPN. Proxies are used so that he can link another computer to get online, or use a different service. If it bothers him, he should just turn it off and see if it affects anything else. It could also be malware.
