Why Can’t I See My Media Devices on My WiFi Network?

Google Home

Episode 1828

Victor from Columbia, SC

David can't see his Google Home device and his Chromecast on his wifi network. Leo says if you're on the same network, and can see both, you should be able to see them. But Google Home uses Bluetooth to signal its presence online, so you have to turn on Bluetooth in order to see it, along with WiFi. You don't have to join it, but you do have to turn it on. You also have to look for Load Media Router Component Extension. Here's a how to, from ScooterX.

What Can I Use a NAS for and Is It Safe?

Synology NAS

Episode 1826

Frederico from Los Angeles, CA

Frederico wants to know what network-attached storage (NAS) he should get and what he can do with it other than backing up. Leo says that he uses the Synology line and you can use it to put an email server on it, a media server, and of course, backup. It's ideal for keeping everything you want protected off the cloud. Leo also recommends turning off SSH (secure shell). It's a popular target for hackers. In fact, only turn on services you use and need. You can also turn on Geographic Blocking to avoid any traffic outside the US. You can also white-list countries and IP addresses. 

How Can I Improve My WiFi Range?

AC2900

Episode 1806

Walt from San Diego, CA

Walt is a farmer who has several high-tech water controllers that are connected by his Asus AC2900 router. But he needs a better range to reach the controllers that are at the extreme end. Leo says that WiFi goes about 100-150 feet. So those on the edge of that will fade out depending on the conditions. Leo thinks a mesh system would be beneficial, but Walt says that the controllers don't support MESH. Leo says that may be due to the 5GHz band. Orbi makes an outdoor router system that could work, but he'll have to make sure it doesn't connect to 5ghz.

 Sidewalk

Episode 1801

Amazon Sidewalk will begin operating on June 8th, and it's got the media sounding what Leo calls a scare tactic.

How Can I Assign IP Addresses to Everything on My Home Network?

IP Address

Episode 1784

Mark from Studio City, CA

Mark's home wifi modem has run out of ethernet ports. So he bought a five port gigabit switch, but nothing really works. Leo says that everything has to have a unique IP address, so a switch won't work. You need a router, which will assign unique addresses to everything you need to plug into your network. Connect the switch to the router's ethernet port, and then the router will assign the IPs as needed.

Should I Wire My Home for Ethernet?

TWIG

Episode 1733

Frin from Phoenix, AZ

Frank has been watching Leo's podcast This Week in Google (TWIG), where he talked about wiring his home with Cat6 Ethernet. Everything is wired for better streaming and no congestion. It also included home theater equipment called "Araknis" which enables a tech person to dial in and fix anything wrong or set it up. Leo wasn't a fan because he never got credentials to do it himself. So, he had it removed in favor of Ubiquity's Unify system. It works great.

Frank was thinking about getting the Araknis though. Leo says it's expensive. Leo recommends the Ubiquity UDM Pro. 

Should I wire my house with ethernet?

eero Mesh Router

Episode 1728

Vip from Monument, CO

Vip wants to know if he should wire his home with ethernet cable while he has the walls open. Leo says ABSOLUTELY. And use Cat6 while you're at it to future proof it. Hardwired is always preferable to WiFi and it'll be faster, have far fewer dropouts, and no congestion. Leo just did it himself. We're lifting a lot more data now with WiFi and IoT smart devices. There's a lot of congestion. 

If you have a challenging wifi environment and can't afford to wire your home, Leo advises going with a Mesh router: eero, Netgear's Ubiquity, even Asus has gone mesh.
