Ed has a Google mesh router system and he wants to be able to get Wi-Fi out in his barn, which is 100' away. Can he get another mesh unit or should he do ethernet? Leo says that if he has a window, then he could put a mesh unit on the windowsill, and another in the window of a barn so they would have line-of-sight connectivity. It's certainly worth a try. Ed could also try powerline networking if the barn and his home are on the same junction. The other option is to use a Wi-Fi antenna.
Wi-Fi is great when it works, but all too often there are problems that cause disconnects or slowdowns. If you have a large house, or there are too many walls that make it hard for signal to travel through, you may need more than just one wireless router.
One option for improving your reception is to set up a secondary Wi-Fi access point to extend your current Wi-Fi router. You'll want to buy an extender from the same company that made the router you already own. Set up the extender in "bridge mode" and it will rebroadcast the signal and extend its range.
Joe is having issues with terrible Wi-Fi downstairs. Leo says that there are two ways to improve Wi-Fi:
Cody just moved to a new house and the Wi-Fi internet upstairs is super slow. Leo says that Cody could put another router upstairs. If he puts the router in bridge mode, it will extend the Wi-Fi signal. There's a new way to do this, however. It's called Mesh Networking which uses a secondary signal, and doesn't just pass along the original signal.
Alan "geeked" himself into a corner trying to protect his family on the internet. Leo says that OpenDNS is the best option because he can block unwanted websites from the DNS level. That prohibits teens from getting around it. He can change the DNS settings to OpenDNS at the router and it has great filters he can use. Then he can password protect the router so they can't bypass it.
