Lynn's wifi drops out from time to time. Leo says that's usually an indication that your router is worn out, but if it's new, then it could be congestion from other WiFi signals in your neighborhood. Using a dual band router with a 5Ghz frequency, that can help, because not only are other routers using 2.4Ghz, but there's also all the smart devices that use them as well. So it's really congested out there.
Ryan got a new modem because his ISP is now giving him faster download speeds. But when he plugs in his router, it slows down to a crawl. Leo says that since the router is new, it should be fine. Try a different ethernet cable. If the cable is old, it may not handle the bandwidth. Then, try another computer and see if you can replicate the issue. If you can't, then that will point to something on your computer. It may be the ethernet port is too old. Also, update the firmware of your router.
Jenna is a veteran and she doesn't use her tablet much. She's thinking of selling her tablet and going with a cheap phone and a cheap internet plan. Leo says that's a good plan, especially if she goes with a low-cost data plan with WiFi. T-Mobile has a plan for those over $50. It's pretty cheap. But there's also MINT Mobile, an MVNO that resells phone service from T-Mobile. $15 a month or less, and she can bring her own phone.
Corey bought an ORBI MESH router and enjoyed 350MBps downloads, until recently. It's now down to about 10MBps. He tried another Linksys mesh router and the same issue happened. Leo says that it sounds like the problem isn't at the router level. Leo suspects that Corey may get full speed from a wired router. If so, then there's a congestion or interference issue. It could be a "WiFi hostile" environment that is causing interference. Maybe a lot of devices are clogging up the wireless spectrum where he is.
Rick hears that Wifi and cellphones can cause cancer due to radiation. Leo says that there is a lot of disinformation out there and fearmongering. Radiation from these sources exist, but they diminish rapidly with distance. There no known issue with WiFi or Cellphone waves... not even high power electrical lines.
Signify has created a new light bulb that has light-emitted wifi, called Trulifi, which can transmit data at speeds up to 150 megabits using light waves.
Earnest's phone automatically changes time zones whenever he goes to Disneyland to a specific area in the park and wants to know why it's doing that? Leo says there's a setting in the phone that he can turn off to prevent it from automatically setting the time zone. But Leo also thinks it could be that the cell site in that area of the park is misconfigured to the wrong time zone, or depending on if he is on a WiFi network, that network is configured to a specific time zone.
Brian upgraded his WiFi router network, but he's still running into buffering and congestion. Leo says first check to see if your connection is the issue by bypassing the router and wire the modem directly into your laptop. Run a speed test and see how it works. Once you've eliminated the cable connection, then you can look to your hardware. But it could also be good old fashioned neighborhood congestion. If you look at your wifi connection, you can see how many wifi devices your router sees. It's not only everyone streaming Netflix anymore.
Jim lives in a congested area and wants to be able to pick up his wifi signal from anywhere in the neighborhood to talk to his yard sprinkler unit with his smartphone. Leo says if you can talk to the control unit, you can talk to any individual unit within WiFi distance. But that's a call to your manufacturer support.
Dave would like to send his internet connection to another building on his property, a few hundred feet away. Should he use a WiFi access point? Leo says that's limited to about 150 feet. Leo says that the longer the distance, the slower the speed. A Ubiquity device is better because it goes point to point that directs the signal to where users want it. Leo recommends visiting RadioLabs.com to learn the difference and find out how to install and configure it.
