Wi-Fi routers, home servers, virtual private networks, and more.
Joseph wants to know why his Wi-Fi speed is slower than it should be. Leo says it could be a variety of reasons, like distance from the access point, the amount of metal in his home, and the number of devices on the same network and bandwidth. The fastest speeds are received by being hardwired directly into the router.
Marion's sister is heavily into gaming and wants to hardwire her PC to the network to get better gaming performance. Leo says that hardwiring is always going to be a bit faster than Wi-Fi because of wireless congestion. Leo says ideally, the best way to do this is to lay conduit from room to room and snake CAT6 ethernet all over the house. That requires opening the wall and is usually best when building a home. She also may need a switcher to handle the traffic around the house.
Jonathan has three iMacs and he's looking for a backup solution for all of them. He uses SuperDuper for one. Leo says that one choice is an external hard drive for each, but that wouldn't do off site backup. That's why Leo recommends using a centralized Network Attached Storage (NAS) and backup to that. Synology is a good option.
Bret is having issues accessing wireless cameras due to blocked ports on his router. Leo says what he wants to do is "port forwarding," and it may be that he'll want to use a higher, five digit port to connect to them. The lower port numbers may either be reserved or in use, like 8080. He should try going higher. He'll also need to use ports that his devices understand. So Bret should look in his manual to see what ports the device supports.
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.
