Richard was trying to transfer over his photos from his camera to his phone via Wi-Fi, but he can't find them. Leo says he does the same thing with his Sony because it's NFC enabled. But he'd need an app to do it. So if he doesn't have the app, then it may not have been received.
Luis can't connect to his Wi-Fi at his house, but he can connect to other Wi-Fi networks. Leo says that the first thing to do is connect via ethernet, just to make sure he can connect wired. Then he should try and join the Wi-Fi while he's right next to the router. If he can't connect, he should try rebooting the router. Then reboot the laptop. Then try wired again. It could be a handshake issue.
Richard turns off Wi-Fi when he's recording from his Android phone with TuneIn Pro. Now he can't turn the Wi-Fi back on. It does work in safe mode, though. Leo says that means an app is causing the problem. Could be a bad update. He should try resetting his phone. He should make sure his photos are backed up to Google Photos, and that he has his Google contacts backed up. Then go into pure recovery mode and wipe everything. He can also back them up to his computer via MTP. Once that's done, the issue should be fixed.
Mike's iPhone 6 Plus isn't accessing his Wi-Fi consistently. It keeps getting bumped off. Leo says that sometimes Apple products can be a bit promiscuous with Wi-Fi because it's always looking for a stronger signal. But it could be the settings in another device that has Wi-Fi access that's luring his device away.
Eric has free Wi-Fi in his neighborhood, but his signal is pretty weak. Sadly, he doesn't have access to the router. How can he use an extender to pass the signal along? Leo says that he'd ideally want to boost both transmission and reception, but without access to the router, he can't do that.
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.
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.
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.
Eric is having trouble syncing his wife's Fitbit with her phone. Leo says that the Fitbit will use Bluetooth to sync to the phone with the Fitbit app. Eric will have to pair it. Then she can use her cellular data to upload her Fitbit data to her account. The Fitbit doesn't need Wi-Fi to work -- it just needs Bluetooth to connect to the phone.
