Why doesn't Uber know where I'm at?

Uber for iOS

Episode 1417

George from Santa Monica, CA

George uses his iPad to call Uber, but they don't know where to pick him up. Leo says that's because the iPad doesn't have GPS. The app just has to ask for the address of where he is in order to find him. With a mobile phone, they would have his coordinates in the app. Without GPS, the app has to use other means to find his general location, usually it uses "WiFi triangulation," and that's not always very accurate. The app puts a pin where he is, and if it's using WiFi triangulation, the pin just goes close to where he is. The good news is he can move the pin in the app.

Why won't my Lenovo Yoga connect to WiFi?

Lenovo Yoga 2

Episode 1411

Carrie from Hermosa Beach, CA

Carrie has a Lenovo Yoga 2 convertible and it won't connect to the internet. It's asking for an adapter. Leo says that the Yoga is wireless, so it shouldn't need an adapter. Leo advises going into the Device Manager by pressing Windows Key and typing "device," then pressing Return. This will show her a list of all her hardware. That will show her if there's a problem with the networking device. She can delete it and then restart the machine. Windows will then reinstall the device driver. There's also a WiFi on/off switch.

How can I get details on the signal strength of my wireless network?

WiFi Explorer

Episode 1411

Keith from Phoenix, AZ

Keith wants to know how strong his WiFi network is. Leo recommends WiFi Analyzer. For the Mac, there's WiFi Explorer. It will give him a line graph with signal strength according to channel. It's $20.

He can find other WiFi analyzer apps at netspotapp.com. It may be that all he needs to do is reset his WiFi settings.

How can I improve the WiFi in my house?

TPLink AC1750 Wi-Fi Range Extender, AV1200 Powerline Edition

Episode 1406

Jose from Burbank, CA

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.

How can use my Internet of Things devices with a mesh router?

Eero

Episode 1404

Ken from Covina, CA

Ken has an Eero mesh router, but he's concerned because he has several "internet of things" devices and he hears that mesh routers don't like them. Leo says that is the current problem, and it may be that the devices aren't smart enough to handle the mesh way of handling the network. They're working on it and Leo says that a fix will some sooner or later. But in the meantime, hardwiring to the router may be the best solution.

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

OnePlus 3

Episode 1399

Jasper from Denmark

Jasper is having a hard time connecting his OnePlus phone to Wi-Fi, and the apps time out. Leo says that if it only happens at home, it may not be his phone. He should go connect to a different Wi-Fi hotspot and see if it's happening. If it connects OK, then it may be that his router is having trouble with his phone. Sometimes that happens and it requires a reboot of the router. Leo also says how he holds his phone can also affect how it receives a signal on the OnePlus. That may or may not be contributing to it.

Why do I have trouble connecting to Wi-Fi on my phone?

Wi-Fi

Episode 1392

Barney from New York City, NY

Barney travels a lot. When he gets to a hotel, he has trouble connecting to the local Wi-Fi network. It doesn't always work. Leo says that mobile devices use a system called "captive portal," where it goes to a middle man (usually the hardware company) and then connects in order to agree to the terms and conditions. It can take up to a few minutes for that to happen too, depending on the traffic. Most are impatient and give up. It really comes down to sitting and waiting. Barney can also try going to the Safari app and typing in "captive.apple.com," which may trigger it.

Why is my Wi-Fi network so bad?

Netgear Orbi

Episode 1392

Ted from Apple Valley, CA

Ted is having trouble with his Wi-Fi. Leo says that's not really the fault of his network so much as it's just congested from everyone else's networks and activity. Also, Ted is streaming 4K video and that takes a lot of bandwidth. It may be that Ted's ISP just isn't giving him the bandwidth he needs to consistently get a good stream. On top of that, anything they publish gets cut in half when streaming via Wi-Fi and with the congestion and the bandwidth, that's quite a challenge to overcome.
