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.
Dan has his TV set up with WiFi about 150' away from his WiFi. How can he improve the connection? Leo says the walls may cause interference. Ben could try setting his WiFi router higher up. But the better option, if possible, is to wire the TV directly to the modem. A mesh router will also help, since it can create a mesh of connectivity, with a separate backchannel. Each Satellite is connected by ethernet. It'll improve it, but it will still deal with interference. He can rewire the home with ethernet. That'll fix things. Also, powerline networking may work as well.
Bruce has Wi-Fi coverage in his house because it's long and narrow. He doesn't want extenders. So he's thinking of using Cat5 ethernet. Can he take an ethernet connection and convert it to Wi-Fi? Leo says that the TP-Link EAP225 access points will do the trick. He can also turn his router into bridge mode for that. But he can also use Powerline Networking, where he can use his electrical grid for networking and get internet access in every room. He can just plug in the Powerline adapters.
John has a private gate and he needs to connect it via Wi-Fi so he can have a doorbell camera there, but his Wi-Fi range is limited. Leo says that since he has power out there, Leo recommends powerline networking to do it since the electrical lines are already laid. The doorbell camera may be hard because of the speed from the powerline, but Leo thinks it's doable. He recommends TP-Link. The downside is that he'll need to have it all on the same circuit.
Henry wants to extend his Wi-Fi upstairs. What extender should he use? Leo says he has a few options. Mesh routers are great because they have satellites that he can plug into each room, creating a wireless grid for his home. These usually come with a base station and a few extenders. They're a bit pricey, but they have the advantage of having full duplex communication, so the speed isn't cut as it's passing along the signal. They also have great security features, they're easy to maintain through the app, and they update automatically.
Herwin wants to extend his Wi-Fi access throughout his house. How can he do that? Leo says he can use a Wi-Fi extender, but it's half as fast as the router itself because it's talking to the router half the time. Powerline Networking could work. It can be slow depending on the wiring, but it's worth a try. Leo recommends TP-Link.
John is a landscape contractor and he's making the transition to Wi-Fi controlled sprinkler systems for his clients, but there are some locations where the Wi-Fi is just too weak to connect. Is there a booster device he can use? Leo says that he can do that, but he'd need boosters for both directions.
Jose has issues with WiFi reaching to the back bedroom in the house. He gets practically no signal at all on his phone back there either. He's told it would be a major issue to move his base station to make it better. What should he do? Leo says that it's a common problem that is largely due to congestion from everyone in the neighborhood. The key is to get an extender. He'll want one that's from the same company. It will cut his bandwidth in half, however, so that's not an ideal solution.
Is powerline networking a decent option these days? Leo says that it's improved a lot since it was introduced 20 years ago. It was horrible back then. Now it's much better. He won't get the full throughput, though – Only about 60%. And he'll have to be on the same fuse box. Leo also recommends the Plume routers because they have ethernet connections as well, so he could plug in there.
