Why can't I attach my NAS to my new router?

Paul from Lake Forest, CA

Episode 1339

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.

How could my son get a job in IT?

Manny from Parkland, FL

Episode 1337

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.

Why is my streaming so unreliable?

Ray from Los Angeles, CA

Episode 1326

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.

How can I monitor bandwidth on my network?

Episode 1322

David from Australia
Apple Airport Extreme

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.

What is a proxy?

Jay from Providence, NC

Episode 1322

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.

Why doesn't my old laptop connect to the internet?

Sue from Redondo Beach, CA

Episode 1316

Sue bought a new router/modem and her laptop won't connect wirelessly anymore. She's been told that her network card is bad. Leo recommends taking the laptop to a coffee shop to see if it connects via Wi-Fi. If it does, then it's just a configuration issue. Since the laptop is Windows Vista, she wants to just get a new computer. Leo says that's a much better option since Windows 10 is far better than Vista.
