Using a smartphone as a hotspot is a common scenario for many users when landline internet is unavailable or unreliable. However, wireless connections often don't provide the necessary speed or stability, especially when working with large files or video conferencing. In these situations, a wired connection comes in handy, guaranteeing minimal packet loss and higher transfer speeds.
Connection iPhone Connecting a computer to a USB cable for internet sharing, known as a USB modem, has several undeniable advantages over traditional Wi-Fi. Firstly, there's no signal lag, and secondly, it simultaneously charges the device, which is critical during long work sessions. In this article, we'll cover the setup process in detail, potential driver issues, and tips to help you stay online.
It is worth noting that the method works on both operating systems Windows, and on macOS, although the driver installation process in the first case requires a little more attention. Before you begin setup, make sure you have an original or certified cable, as cheap alternatives often only support charging and cannot transfer data.
Advantages of a USB modem over a wireless connection
Why choose a cable over a wireless network? The main reason is connection stability. Wi-Fi signal A wired connection is susceptible to interference from other routers, microwave ovens, and even walls, resulting in ping spikes. A wired connection completely eliminates this issue, providing a direct connection between your smartphone and computer.
In addition, using a USB port allows for significant battery savings. When actively distributing the Internet over the air iOS The device heats up and drains quickly. This cable solves this problem, turning the smartphone into a fully-fledged external modem with constant power. This is especially important for owners of older models whose batteries have lost some of their capacity.
Another important aspect is security. Transmitting data via a cable makes it virtually impossible for hackers to intercept it, unlike open or poorly secured wireless networks in public places. You create a local, secure network that only your PC can access.
- 🔌 Stability: No interference or sudden connection breaks typical of radio waves.
- 🔋 Energy efficiency: The phone charges while you work, without requiring pauses for recharging.
- 🚀 Speed: Maximum channel throughput without losses due to over-the-air encryption.
- 🛡️ Safety: Physical access to the cable is required to intercept traffic.
⚠️ Please note: Some mobile operators may block or charge separate rates for tethering. Before activating tethering, check your plan's terms in your operator account to avoid unexpected charges.
