Bob recently bought an eero mesh router. It worked fine for two weeks and then he started experiencing dropouts, and he can't get support. Leo says that support is terrible these days because of limitations due to CoVid. Another thing to look at is your ISP and cable modem. Security software could also be an issue and can inhibit your internet access.
Cherry wants to know if a mesh router would work in a house made of concrete blocks? Leo says that concrete blocks need rebar to stay standing, and rebar turns your home into a Faraday cage, which blocks wireless signals, and that means no WiFi outside of the main room. It's death to WiFi, so Mesh may not help at all. But that isn't the only solution. Leo says that if you have CoAx in your home, you can convert that to wired internet. You'll need a NOCA adapter (Networking Over CoAx cable). You can also string ethernet, but the simplest solution may be powerline networking.
Bernie has two desktops, one with Windows 10, the other with Windows XP. But they can't see each other on the network. But his Windows 7 laptop sees both. Leo says there are so many things it could be; he recommends going to practicallynetworked.com. It could be the XP machine is using SMB 1.0. Windows 10 stopped using it because it wasn't secure. So chances are, that's it. You can still turn it on though.
John has been upgrading his parents' network with a new router, some smart devices like NEST Cams, etc. He's running into some issues, though. He suspects it's the modem/router combo. Leo says it likely is: you'll need to find the IP address and log into it. Likely Admin/Blank for a user name and password. Then turn off the wifi and DHCP. The DHCP is also doing double NAT, so turn that off. It's called putting the router side into "bridge" mode. Let the modem send the bandwidth to the Google home router and it will handle it all. That should fix it all.
Jack got an antivirus notification that an Apple TV that was trying to access his network. He said no, but it keeps requesting it. Leo says that if Jack has an Apple TV, it's probably trying to connect. It uses a utility called BONJOUR to connect. It's perfectly safe to talk to your mac. And since Jack has a router, his router is a perfect firewall to prevent outside connections. That's how he'll know it's the Apple TV that's trying to connect. So let it. And get rid of the AVS.
Tony wants to know if guest network accounts safe? Leo says yes, they are. But it greatly depends on how they are implemented. It needs to be sandboxed from the rest of the network so it can't get access to your computer data.
Tony has a Synology NAS, but the public folder disappeared from his Windows PC. And Windows won't let him browse to it. Leo says SMB has to be enabled for the folder to be discovered. It's the networking protocol that Windows uses. It will also give you a password challenge. But once you input the password, Windows should remember it.
Chris has everyone set up with WiFi through UVerse DSL, but he wants to move away from it because it keeps going down. Leo says that UVerse DSL really isn't' all that great. It's not like UVerse Fiber. He would like a hardwired system to his Eero. Leo says Eero has beacons to cover the space. Two would be enough (one base, one beacon). The benefit is that Mesh routers have a second back channel to talk between the MESH devices. That makes WIFI much faster.
Sam looked in the settings of his Netgear Orbi router and made a few changes. Now, many things he uses on his network don't work any longer. Leo suggests powering down the router, count to 30, and then power it back up. If that doesn't work, you can completely reset the router. There's a reset hole that you poke a paperclip into and hold it until the lights blink yellow. You'll need to reset it up and give it a new password, but it will be back to the factory settings. Also turn off WAN administration, and universal Plug n Play (UPnP). You'll be back up and running.
Tom's router has four ethernet ports. Should he use them to install multiple hubs with switches or multiple switches? Leo says that switches aren't very smart on the whole, and switches are really just another name for hubs. What he needs is a smart switch to really isolate the traffic and maximize speed. Leo has a 24-port switch connected to his Orbi router and he uses that to connect all his devices that need a wired connection. That includes his streaming box and TV.
