Unlike modern Ultrabooks, older models Sony had specific switches and software utilities that required special attention. Wireless connection — is a critical component, and its correct configuration ensures stable operation of the entire device in a home or office network.
In this article, we'll detail all possible methods for activating the module, from physical switches to complex reinstallation of system components. You don't need to be an IT expert to handle this task if you follow a logical sequence of steps. We'll cover the nuances of working in the environment. Windows 7, 8, and 10, since these are the systems most commonly used in this equipment.
