Ray has a friend who just bought a MacBook Air and he's having trouble connecting to his Canon wireless printer. He can print fine hard wired, but not wirelessly. Leo says that he's used a Canon Pixma wireless printer for years. The question is will it print with any other computer. If so, then it isn't a network issue. Leo says to remove the printer and then add it again. It may have had a problem during adding it. Leo also recommends using the Apple drivers.
When it comes to securing a Wi-Fi router, there are a lot of things people often do that aren't actually effective. For instance, hiding the name of the router (the SSID), won't help. Another scheme that's particularly onerous is MAC address filtering. Every computer has a unique MAC address, and the router can be set up to only allow computers with known MAC addresses to access the network. This technique is used by businesses and schools, but it overlooks MAC address spoofing.
Thomas wants to host a Minecraft server for his friends. Is port forwarding secure? Port forwarding is where you tell the router to send traffic coming in from a specific port to a certain machine. This limits a little bit of the potential damage from opening up a server to the outside world, but it will ultimately depend on that Minecraft server to be secure. It's important that Thomas keeps his Minecraft server secure and up to date. If someone can figure out how to get around his network via the server, he could infect his network.
Earl bought an HP Windows Home Server and now that it's not supported by Microsoft anymore, he wants to know if he can convert it to a media server. Leo says sure! Just because Microsoft doesn't support Windows Home server doesn't mean it won't work anymore. It's fairly straight forward to set up. The real challenge will be digitizing everything. Once it's all digitized, it can be stored and made available by all computers on Earl's network. Paul Thurrott of winsupersite.com was a huge fan of Windows Home Server.
Thomas has a Windows 8 machine and he wants to set up a home group for file and printer sharing. But his machine doesn't appear. Leo says that Microsoft has a technote on it, and it may depend on what version Windows he has. Some versions would allow him to join a home group, but not start one. Secondly, he should look at his security settings to make sure all machines are sharing. Add the machine name to the user name as well.
At his job, Justin has gotten into IT work and now he wants to get some formal education. Leo says that since Justin has worked in it for the last 5 years, he's got to be pretty accomplished. But he doesn't have a certification. Leo says that certs are for guys just starting out, not for experienced people. Leo says if he really wants his certifications, he should check out IT Pro.TV, which has an online monthly video subscription that will take him through everything he needs to know. Justin could go to a local Junior College as well.
Jordan has a 6 TB RAID array that stores all his video footage for his company. He's having a difficult time keeping track of all the video that has to be distributed online, though. PadreSJ in the chatroom says that there's a program called Digital Fountain that does real time data transport. That's an enterprise solution. There's also BrightCove Video Cloud.
Dave has a home office in his garage and he wants to get Wi-Fi out there, rather than having the wired connection. Leo says that he should be able to get Wi-Fi for at least 150 feet. If he has a lot of wiring in the walls, then he could end up with slower Wi-Fi, or even a dropped signal. The easiest thing to do is to find a repeater that's the same brand as his Wi-Fi router. They're essentially routers that are in "bridge" mode.
Jay wants a router that can access the fastest DNS on the net. Leo says that would be a great feature. Steve Gibson has a program that can find them, but Leo doesn't know of any routers that have that built in.
