Why can't I use Chromecast with the Linksys Velop mesh router?

Episode 1378

Albert from Las Vegas, NV
Google Chromecast

Albert bought a Linksys Velop Mesh Wi-Fi router, but it doesn't work with his Chromecast when trying to cast something from his Chrome browser on the desktop. His mobile devices do work, however. His Chromecast can get it on the network, but he can't see it from his desktop browser. Leo doesn't think there's a particular problem with the Velop and the Chromecast. If the computer and the Chromecast are on the same network, he should be able to cast to it.

Do I need a managed switch for my network?

Episode 1378

David from Palm Beach, FL
Ubiquiti EdgeRouter X

David has multiple TVs and computers and would like to link them all together with a switch. Should it be managed or unmanaged? Leo says that networking is a high end technical topic. A router manages the traffic and routes it through to the proper device. Routers use QOS or "quality of service" to do it. A switch is still needed, though, and it reduces traffic. A managed switch would allow him to run protocols and control the network properly. Most people don't need a managed switch.

What router should I buy?

Episode 1377

Paul from Columbus, OH
TPLink Archer C7

Paul's daughter has a really old router and it's starting to flake out, so it's time to get a new one. Leo says she should get a dual band router that supports not only 2.4 Ghz, but also 5Ghz. She'll want one that supports 802.11ac. The reason to get a dual band router is that everyone is on 2.4 these days, and while 5 GHz is limited and won't go through walls, it is barely used.

How can I find out what devices connect to a router?

Episode 1374

Isaac from Los Angeles, CA
WiFi Pineapple

Isaac is a cop and wants to know if routers collect data of what connects to it or sees it. Leo says only if the device was connected to that router. Just seeing it is another matter, and that's unlikely. Android has an app called WiFi Collector from NirSoft, but that's the opposite direction from what Isaak wants. Leo says that the WiFi Pineapple from HakShop could work for this.

Why can't my Blu-ray player pick up my Wi-Fi signal?

Episode 1372

Susan from Yorba Linda, CA
TPLink 2-Port Gigabit Passthrough Powerline Starter Kit

Susan is having trouble streaming with her Blu-ray player and her TV. Leo says it could be that the Blu-ray's Wi-Fi isn't working too well. She may need to move her hotspot closer to the TV itself. It may also be that there's congestion on the 2.4 Ghz band, and her TV won't pick up the 5.0 Ghz band. She should try using her mobile phone as a hotspot and see if it picks it up. If it does, then the Wi-Fi spot is either too far away or is congested and swamped by other signals.
