John wants to set up webcams on his property and access them at work. Leo says he won't want to host those at home. He'll want to use a third party service for that. It has to run multiple cameras and from all angles through one stream, though. Leo recommends Nest Cams, which he can access online. Streaming all of those cameras will kill his bandwidth, but using one would be fine. It would send the stream to DropCam and then he can access it through a browser which can be accessed by multiple computers.
Naomi has been helping a senior with surfing the net through a Chromebook. Leo says that Chromebooks are a great option for people that have limited uses like just checking your email and Facebook. It's a solid option, especially for retired people. It's more secure, reliable, and far less expensive than a general purpose computer which is really overkill for most people's needs. A Chromebook is fantastic in that regard.
Johnny Jet is cruising on the Rhine and while it's not for everyone because there's not a lot to do, it's very relaxing.
App - Groupie. Create an album. Upload it, and share with others, who can also upload images to the album. Available on iOS and Android. Great for group trips.
David got a new modem called an ActionTek, but it doesn't work very well. Can he buy his own? Leo says he's not a fan of ActionTek. But David will need to call his provider and ask them if he can use his own modem. They will almost always say yes. For DSL modems to buy, Netgear makes a good DSL Wi-Fi router/modem. Zyxel also has good router/modems, but they're more expensive.
Richard has a friend who's Mac is running slower. Is that because her machine is getting older? Leo says maybe, but it may also be that her hard drive is getting less reliable. As the hard drive gets older, it starts to have to work harder to process data. It begins to cache data more. So replacing the hard drive, especially with an Solid State Drive, can make a world of difference in speed. Updating your OS can also help, though if it's too old, you may not upgrade to the latest (El Capitan). Leo says there's a few easy things to do like resetting your browser and clearing the cache.
Dan wants to know about a VPN. Is it good for security? Leo says absolutely. VPN stands for Virtual Private Network and it's essentially an encrypted tunnel through the Internet where your data cannot be seen by anyone sniffing around. All anyone else would see is gobbelty-gook. It's great for security if you're at an open Wi-Fi network like a coffee shop. VPNs are really popular for work, where you're working from home but want access to your work server.
Harry is reinstalling the Windows Vista OS on a friend's computer and now it's connected to "an unidentified" router with a local access only. He can't get online. Leo advises connecting via hardwire. If that works, then it's a setting that's not allowing it to get online. A driver may need to be downloaded as well. Getting the motherboard drivers from the manufacturer could solve it.
Hope uses Windows 10 and when she goes to a website, she doesn't see any images, just text. Leo says to refresh the page to reload. She can press Shift F5 and that will reload the page. There may also be something that's blocking all the images, like a plugin or extension. Hope uses an ad blocker and that could be doing it. Leo has a hunch that something is running on the system that's blocking it. It could be an overzealous antivirus program. There could also be an extension in Google Chrome that is blocking it.
