Researchers at UC Santa Cruz developed Pulse-Fi, a system that uses WiFi signals to monitor heart rate without sensors or wires, by analyzing variations in WiFi channel information caused by heartbeats, potentially enabling wireless health monitoring and other RF-based detections.
Chipmakers are celebrating the advent of AI-powered PCs, calling it the most exciting development since the birth of WiFi.
Tesla's latest update brings the ability to hide unused music services and explicit content, as well as changes to WiFi and Bluetooth menus. Additionally, Elon Musk announced plans to produce the Tesla Semi in Europe at Giga Berlin, aligning with the company's expansion goals. The update also includes changes to turn signal icons and the introduction of a new WiFi menu, reflecting Tesla's ongoing efforts to refine its software and enhance user experience.
Security researchers have demonstrated how hackers can use a simple $169 hacking tool to create a fake "Tesla Guest" WiFi network at Tesla charging stations, steal owners' login credentials, set up a new phone key, and potentially steal their Tesla vehicles. Despite reporting the issue to Tesla, the company has not acknowledged it as a problem. The researchers suggest that requiring physical key card authentication and notifying owners when a new phone key is created could mitigate this vulnerability.
Google has removed the Google Wifi and Nest Wifi routers from its store, possibly in anticipation of a new model. Last year, Google introduced the Nest Wifi Pro with Wi-Fi 6E connectivity and Matter support, and it's speculated that a new Nest Wifi model codenamed "Brezza" may be on the horizon. While the older hardware is still available at other retailers, stock is expected to deplete in the coming weeks.
Valve has released a new Preview update for the Steam Deck's operating system, SteamOS 3.5.13, which includes improvements to WiFi connectivity and a new feature allowing users to adjust the brightness of the Status LED. The update also fixes an issue with HDR being desaturated on some external DisplayPort displays. Users experiencing WiFi issues may find relief with this update, which builds upon the previous 3.5.12 Preview's WiFi crash-fix. To access the Preview, users can navigate to the System Update Channel settings on their Steam Deck and select Preview.
Mounting your WiFi router on the ceiling can significantly improve performance by placing it in the center of the room, away from walls and obstructions. This not only enhances reception but also declutters living spaces. To achieve this, you'll need a ceiling mount compatible with your router, a drill, cord cover, and possibly a longer power cord. The process involves deciding on the router's position, securely attaching the mount with screws, and neatly arranging the cords with cord cover. This simple and cost-effective solution can lead to better WiFi connectivity and a tidier home.
Linux 6.6.6 has been released to address WiFi regressions caused by a patch in the previous version. The patch had resulted in deadlocks and issues with user-space network managers. Linux 6.6.6 reverts the problematic patch and is now available as the "666" kernel.
The new 2023 Fire TV Stick 4K Max, featuring improved WiFi 6E and a quad-core 2GHz processor, is currently on sale for $44.99, while the Fire TV Stick 4K is available for $29.99. The upgraded version offers better WiFi performance, particularly for those with weaker connections, and delivers noticeable speed and performance improvements over older Fire TV Stick models.
The article discusses the security differences between using cellular data and WiFi for mobile phone connections. While both options can provide security, cellular data is generally considered more secure due to encryption protocols and the active security measures implemented by mobile network operators. However, WiFi networks can be made secure by following certain steps such as creating a strong password, using a guest network, encrypting the network with protocols like WPA2 or WPA3, keeping the firmware updated, and avoiding public WiFi. Ultimately, the choice between cellular data and WiFi depends on individual preferences and circumstances.
While wifi has become the norm for internet access, there are still several advantages to wiring your house with ethernet cables. Ethernet offers faster and more consistent speeds compared to wifi, with studies showing that wifi networks typically achieve only 42% of the speeds of a hardwired connection. Ethernet also provides more reliable coverage, eliminating wifi dead zones, and offers better security as it is a physical connection rather than a signal in the air. While wifi technology continues to advance, wiring your house with ethernet remains a worthwhile option for a superior internet experience.
Tech expert Axel Hernborg recommends turning off the "Ask to Join Networks" setting on iPhones to avoid unnecessary battery drainage caused by constant scanning for WiFi networks. Manually turning on WiFi when needed can help conserve battery power. Other tips to boost battery life include managing background app refresh and offloading unused apps to optimize storage space.
The Eero Mesh WiFi Router is currently on sale for 29% off, priced at $50. It offers easy setup and coverage for up to 1,500 square feet, ensuring a strong signal throughout your home.
The placement of your internet router can significantly impact the performance of your home network. According to WiFi expert Alex Tofts, routers should not be placed under stairs, near windows, in the kitchen or attic, or next to objects like vases or fish bowls. To ensure a strong signal, routers should be placed in open areas with a clear line of sight to connected devices, away from obstacles that can interfere with the signal. Elevating the router and keeping it cool are also recommended for optimal performance.
The ASUS ROG Ally, a new gaming handheld, is shipping with Windows 11, but it can easily be configured to run Linux. The device features an AMD Ryzen Z1 Extreme CPU and a 7-inch 1080p 120Hz display. However, the Mediatek WiFi adapter is not working out-of-the-box with Linux 6.2, which is the default kernel in Ubuntu 23.04. A kernel patch is pending to resolve the issue.
