Below we will discuss in detail how to activate this function and what drivers may be required for the operating system. Windows and how to troubleshoot common connection errors.
Benefits of a wired connection between iPhone and computer
The main advantage of using USB cables A stable connection is essential for internet distribution. Unlike a radio channel, which is susceptible to interference from walls, microwave ovens, and neighboring routers, physical contact eliminates data packet loss. This is especially important for video conferencing, online gaming, or transferring large amounts of data.
Besides, USB modem consumes less smartphone energy per unit of transmitted traffic, since some of the energy comes from the computer.
