Why does my iPhone keep falling off WiFi?

Mike from Los Angeles, CA

Episode 1207

Mike's iPhone 6 plus isn't accessing his WiFi. It gets bumped off. Leo says that sometimes Apple products can be a bit promiscuous with WiFi because it's always looking for a stronger signal. But it could be the settings in another device that has WiFi access that's luring your device away.

Mike also can't seem to follow Leo on Facebook. Leo says that he has a private facebook page and a public facebook page. And his private page isn't taking followers because it's ... well private. But Mike should be able to follow Leo's public Facebook account.

How can I extend the range of my Wi-Fi to the second floor?

Matthew from Virginia

Episode 1196

Matthew is having issues with WiFi when he moves to the second floor. Leo says it's important to remember that WiFi is about 150' in distance. But things can get in the way and dilute the signal, especially metal. An extender will help but you want an extender that is made by the same as your router. Leo has three of them. ActionTec is what Matthew's router is and they do address extenders here. That's the most affordable option. Then there's powerline networking that uses the electrical cable in your walls as networking cables.

What mobile Wi-Fi hotspot should I buy?

Emily from Orange County, CA

Episode 1192

Emily is thinking about buying a portable Wi-Fi hotspot so that they will have the ability to connect to the Internet with her iPad. Leo says that's a good idea. Are the independent carriers any good? Leo says that there aren't any independent carriers, really. They're just reselling coverage from the big guys (called MVNO) and she'll want to be sure she checks out the coverage maps for the carrier they're reselling. Is Karma good? Leo says that Karma is a Kickstarter campaign that would let her pay as she goes.

Why can't I connect my iPad to my Wi-Fi network?

Garrett from Manhattan Beach, CA

Episode 1191

Garrett has an iPad 2 and he's having trouble connecting via Wi-Fi consistently. He'll connect and then when he goes into his room, it drops. Leo says that Wi-Fi is a radio signal and it has a range of about 100-150', but it can also be affected by what is in the walls. If he has metal in the walls, then he'll have issues connecting. Leo also says the connection may be congested by a crowded 2.4 GHz frequency band. Modern routers give the choice of 2.4 or 5 GHz.

How can I transmit Wi-Fi from a long distance?

Logan from Knoxville, TX

Episode 1182

Logan has to create a long range wireless access point that will enable him to have broadband from up to 10 miles away. Leo says that's a long way for Wi-Fi, even for line of sight, which will help a lot.

Leo suggests checking out RadioLabs.com, they make long range Wi-Fi antennas. He'll need a highly directional antenna, and maybe even microwave antennas, because Wi-Fi may not be the best idea for such a long distance.
