Can my Roku connect to a wifi hotspot?

Eddie from Lafayette, CA

Episode 1454

Eddie wants to know if Roku will look for a hotspot. Leo says it doesn't really matter, the Roku will look for WiFi no matter where it is. But remember that hotspots tend to have more restrictive bandwidth caps, and 1GB an hour is not surprising on Netflix.

Eddie also wants to know if he can block spam in hotmail. Leo says that hotmail is notoriously bad for spam. They want you to upgrade to Outlook, and Leo says it has much better spam tools. You can also put the email into the SPAM folder, as the Spammer is likely spoofing the address.

Why can't I connect my Wemo to the internet?

Episode 1452

Armando from Whittier, CA
Belkin Wemo

Armando is trying to connect Wemo to his wireless router, but when he connects an additional one, it won't take his password. Leo says 2.4 Ghz is extremely congested now, so Leo recommends going into his router settings and changing it to allow his router to make changes automatically. That will enable it to choose the best channels. Doing it manually is tough and he'd need a Wi-Fi analyzer to do it. If he wants to do that, InSSIDer is a good one.

Why can't I connect to the internet on my laptops in Windows?

Episode 1452

John from Biddeford, ME
Wi-Fi

John is having problems with two Windows laptops (one 8.1 and one Windows 10). They will connect to the hotspots, but they won't connect to the internet. Leo says that's called "captive portal" and it requires logging in to gain access. It could also be a security update that is preventing it. It could be closing down a port that he needs to access the internet. He could try reinstalling the network driver.

How can I update my iPhone without wireless?

Episode 1439

Howard from Mission Viejo, CA
Apple iPhone X

Howard just got an iPhone X and he had to restore his iPhone 4 data to it. Leo says the fastest way to do that is to plug it into iTunes, back it up, and then restore to his new phone. It should take about 5 to 10 minutes. But his problem is that his network is wired and he can't get updates because it's Wi-Fi only. Is that true? Leo says not really. He can connect to iTunes, download the updates, and install them.

Why can't I get WiFi in my apartment?

Episode 1422

David from Burbank,CA
WiFi

David lives in a fifth floor apartment with 100 Mbps WiFi available. He can't get it on his floor, though. What can he do? Leo says that WiFi is generally limited by distance and David is just too far away from the access point. He needs one on his floor. If he can get his own modem, that's what he should do. He could also try getting a group together to get WiFi extenders and put a few on every floor. That would help.

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

Episode 1417

George from Santa Monica, CA
Uber for iOS

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?

Episode 1411

Carrie from Hermosa Beach, CA
Lenovo Yoga 2

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.

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