Jim lives in a remote area and he uses LTE as his main internet connection with a 10GB package. He'd like to set up a video security system to check with his cell phone. But since he's hotspotting, he can't use an ethernet connection to communicate.
Che just bought a new Dell XPS Desktop and it's started to slow down drastically. He does a speed test, like Leo taught, and the desktop is much slower than his laptop. Leo says to try plugging the desktop directly into the router with an ethernet cable, and see if the speed improves. If so, then he's narrowed it down to the router. Leo says it could the hardware, but he could try reinstalling the Wi-Fi connection. There may also be conflicting Wi-Fi drivers at work between the hardware driver and the Windows driver. That can confuse Windows and slow things down.
John records his daughter's volleyball games and he's having issues uploading the 4K video. Leo says that's not surprising. We're all uploading more, and bandwidth is usually "asymmetric" where download speeds are much faster than upload speeds. John could pay for the next tier of service. If he has Google Fiber in his area, it's symmetric which is much faster.
Brant has an issue that when he's gaming online, and someone else starts streaming Netflix, suddenly he gets a lot of latency. Leo says that's just because his bandwidth goes down because there's so much being used. One thing Brent can try is QOS (quality of service) where he can set his router to prioritize bandwidth traffic through the ports that gaming and streaming apps use.
Jeffrey wants to know if a larger screen phone uses up more data than a smaller screen phone. Leo says that it could the case when streaming video. Sites like Netflix and YouTube will notice that you're using a high resolution screen and automatically stream higher resolution video, and that definitely uses more data.
Rick has Google Drive, and he's noticed his internet slows down when it's syncing data. Leo doesn't think this is a likely cause for slowing down his internet, because these programs are supposed to be "nice" -- they only will use a small fraction of the available bandwidth. Rick can pause the activity on Google Drive to see if that makes a difference. It could take up more bandwidth during the initial sync.
Archie has a Wi-Fi router and has connected his Roku, but he's not getting good enough reception and it buffers a lot. Leo says the farther the router is from the Roku, the less connection can be made. But Leo also suspects that the router isn't giving Archie as much bandwidth as he needs. It could be due to congestion.
If his router supports the 5 GHz band, it's a much better choice for streaming. He can also take the old router and put it in bridge mode and use it as a repeater to pass along the signal.
Lunella doesn't like the idea of TV being on the Internet. It just uses too much data. Leo says that there's more bandwidth available that we currently use, and it can be expanded infinitely. Having said that, the bottle neck occurs in the "last mile," where the ISP isn't providing enough bandwidth. The real issue is power consumption.
Tamar has been using AT&T for 15 years and she's been thinking of changing her internet service provider. She wants to know if she can keep her AT&T email, though. Leo says no. That's an AT&T domain name and as such, once she cancels her account, the email will get shut down.
Tamar wants to move to Time Warner Cable, but she doesn't want to get rid of her TV service through DirecTV. Leo says she doesn't have to have cable TV through Time Warner, she could just get internet. It may cost her about $10-20 more, though.
George wants to know if he can create his own bandwidth. Leo says that bandwidth is created by a network of devices that provide it's share of bandwidth.The more devices, the more bandwidth. Netflix, for instance, has more bandwidth because it has far more distribution to handle the streaming of video data. And there's other networks that interconnect with each other to create more bandwidth and switches. You can't really create bandwidth at home. The only way he could generate more bandwidth is to pay for it.
