Wi-Fi problems are the worst. 3 ways to solve them.

  Wi-Fi problems are the worst. 3 ways to solve them. Wi-Fi is great when it works — but it never seems to work often enough to let any of us take it for granted. And when you can’t even get a device to connect to a wireless network, it’s not hard to miss the days of laptops that all had Ethernet ports for wired connections that didn’t require entering a password or clicking an “I agree” button on a Web page.But some new and old tricks can help get a phone, tablet or laptop on a Wi-Fi network or at least make it less of a pain to establish that connection.

If you've ever thought of resorting to aluminum foil to redirect your home's poor WiFi signal , it turns out you're not actually that far off the mark. discovered that 3D printed signal reflectors, consisting of a thin layer of metal and plastic, can drastically and cheaply improve the wireless signal around a home.

Signal's secure messaging is now available in a desktop app

  Signal's secure messaging is now available in a desktop app You can already use Signal for secure chats on the desktop, but you've had to use a Chrome web app to participate in those encrypted conversations. What if you don't like Chrome, or would just prefer something more elegant than a browser? Signal is ready to help. It just released a stand-alone PC app, Signal Desktop, that offers privacy-minded messaging without heading to the web. The experience isn't a radical break from what you've known before, but it will make sure that you don't type in the wrong browser tab and reveal your innermost secrets.

If you've ever thought of resorting to aluminum foil to redirect your home's poor WiFi signal , it turns out you're not actually that far off the mark.

If you've ever thought of resorting to aluminum foil to redirect your home's poor WiFi signal, it turns out you're not actually that far off the mark. EurekAlert reported November 8 that researchers at Dartmouth College have discovered that 3D printed signal reflectors, consisting of a thin layer of metal and plastic, can drastically and cheaply improve the wireless signal around a home.

These experiments were based off the idea of using an aluminum soda can behind a router in order to direct the signal away from deadening walls and other obstructions. The team was able to analyze a space and create a custom reflector that would optimize the WiFi signal in that room. They then fed their data into a custom program called WiPrint that designed an optimal plastic reflector and created it using a 3D printer. The last step is to cover the object in aluminum foil and place it on the router. You can see a demonstration in the video below.

Fast Pair is Android's answer to Apple's effortless AirPods pairing

  Fast Pair is Android's answer to Apple's effortless AirPods pairing Apple users are quickly growing accustomed to effortless wireless pairing between the iPhone (or Mac computers) and AirPods, but Google has been working on something that should remove at least some frustration from connecting Bluetooth gadgets to Android phones. Some speakers and headphones let you speed up the pairing process with NFC, which is pretty convenient, but now devices running Android 6.0 and above will get yet another, even better option: Fast Pair.

Fast forward a few decades later and you might still want to use aluminum foil to improve signal strength, only now for your wireless router instead of your TV.Xia Zhou, an assistant professor of computer science at Dartmouth College

Hello MIUI'ers, If you've ever thought of resorting to aluminum foil to redirect your home's poor WiFi signal , it turns out you're not actually that far off the that 3D printed signal reflectors, consisting of a thin layer of metal and plastic, can drastically and cheaply improve the wireless signal around a home.

This solution solves multiple problems with WiFi signals. First of all, it's inexpensive; if you have access to a 3D printer, it will only run you about $35. Directional antennas cost a lot more than that. Second, it allows you control over your WiFi signal, which has more benefits than you think. Not only does it make sure you have signal in the rooms you need it in, but it allows you to cut off signal where you don't. This improves physical security, ensuring neighbors (and unsavory types) can't access your network.

The next step for the team is to figure out how to design reflectors that are made of a different material than 3D printed plastic. The idea is to eventually create an object that can actually change shape if the room's layout changes. This may not expand the coverage area of your router, but it will ensure that you'll get stronger signal in the areas you need it most.
