David is a radio junkie. He loves to stream audio on MetroPCS and he gets a lot of buffering. So he went to Verizon and he has the same problem. Leo says that it may just be the area that David lives in. It could be a congestion issue. But it could also be that since MetroPCS is a second-tier provider to T-Mobile, it's not getting the same service priority for bandwidth. What it may be, is the SIM card. With the new 5G towers, the SIM card may not be giving him the 5G access. So go to the MetroPCS store and get a new, upgraded SIM.
Bill works from home. Lately, he's been running into interference on his wifi network. Leo says that's probably just congested as just about everything now in your home connects to the internet, especially security. And when you multiply it by all the houses in your neighborhood, and that WiFi band is dealing with rush hour. How to keep them all secure? Leo says the best you can do is keep all your devices updated. But change the name of your router and make sure it's using encryption.
Anthony wants to know why if his WiFi will interfere with 5G. Leo says that 5G is fifth-generation cellular and that differs from your WiFi signal. Anthony's WiFi has a different source, frequency, and transmission medium.
There may be home internet via 5G, but that's done via cellular, not WiFi. They're two distinctly different technologies.
Ryan has noticed his WiFi speed has drastically dropped off as of late. Leo says that with everyone at home now, there's a lot of people working at home, streaming, and doing other things online that cause a lot of congestion. Ryan says what's odd is that his mesh router network gets faster if he unplugs one of the satellites. Leo says your mesh network shouldn't slow down if you have an extra satellite connected. The benefit of Mesh is that it has its own backchannel for access point communications. Leo also says that Google's mesh router speed is definitely slower than others like Eero.
Sarafine has images that she puts on a thumb drive, and sometimes they become very pixelated. Leo says that s likely because the image is low resolution, and the metadata doesn't show that it isn't as sharp as it looks. Also, converting an image to JPEG is a mistake because it doesn't scale. So if you're using vector graphics, converting it to JPEG makes it pixelated as you change the size of it. What you want to do is change the size to what you want FIRST, and then convert it to JPEG.
Jeff is having issues with his WiFi coverage at his studio. Leo says that congestion is a major problem with WiFi because of the Internet of Things, phones, tablets, the works. What Leo recommends is Powerline Networking. It's gotten a lot better the last few years and being wired will always be better than WiFi. So check it out. TPLink makes some great PLN devices.
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.
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.
Clarence has issues with his laptop's Wi-Fi intermittently dropping after adding a new modem and Netgear router. Leo says to connect the laptop directly to the router and see if it drops out. If it doesn't, then he'll know the internet connection is fine, and the Wi-Fi radio in the laptop is flakey. If it keeps happening, then that would lead to his router, or even modem. Another possibility is the power-saving may be turned on in the Wi-Fi settings of his laptop. Just disable power-saving and it should be OK from there. It could even be congestion from other internet devices.
Jeff wants to know why his internet slows down at night. Leo says that he ends up sharing bandwidth with his neighborhood and if it's slowing down in the evening, it's because everyone is on Netflix. He also has to factor in Wi-Fi congestion. Jeff could bypass the Wi-Fi router and plug directly into the modem and see if it speeds up. If it does, then he'll know it's Wi-Fi congestion. If not, then he'll know it's his because of heavy use in the neighborhood.
