A major security flaw has been discovered in Wi-Fi and we’re all at risk.
Researchers discovered the weakness in WPA2, the protocol that secures all modern Wi-Fi networks. Any modern device with a wireless connection could be open to a KRACK attack that would expose information like credit card numbers, passwords, messages and more.
One of Android’s best file transfer apps has finally made the leap to iOS. AirDroid makes it incredibly easy to wirelessly transfer all kinds of file formats between your devices. And unlike AirDrop, it’s not exclusively for Apple devices.
iOS 11 brings yet another convenient feature — password-free Wi-Fi sharing. It works like this: If a friend or other visitor needs to use your Wi-Fi, then instead of digging in the dust and yanking on the already-taut cables of your router to read the password label on the back, you can just hold your iPhones close to each other, and grant the guest access to your network. It’s super easy, and requires nothing more than that you both be running iOS 11, and have Bluetooth switched on.
It used to be so simple: If you swiped open the iOS Control Center and tapped the Bluetooth icon, then Bluetooth would be toggled on or off. That was it, and the same went for Wi-Fi.
In iOS 11, tapping the same Bluetooth button doesn’t do that. Instead, the Control Center Bluetooth button disconnects your iPhone or iPad from connected Bluetooth accessories, leaving the actual Bluetooth radio on. What’s more, not all accessories get disconnected. Just what in the blazes is going on here?
AirDrop, Apple’s built-in sharing feature, lets you beam pretty much anything between any Apple devices. You can use it to share photos, videos, URLS, documents, snippets of text — in short, anything that can be shared using the standard “sharing arrow” icon is fair game for AirDrop.
AirDrop really should be your first choice for sharing, because it doesn’t use the internet to send the files. It connects you and the recipient directly to each other using Wi-Fi, and makes the transfer that way. This makes AirDrop secure and lightning-fast. It also mean it works as well on the top of a mountain as it does in a busy office.
With iOS 11, your iPhone gets smart enough to realize when a Wi-Fi connection is flaky, and gives up trying to join it. This might be most useful if you’re one of those people who keeps your Ask Join Networks setting activated, but it should help anyone who uses their iPhone in multiple places — i.e. everyone ever.
