Connecting to the Internet is one of the most important uses for a PC, and users often use Wi-Fi and mobile broadband to connect to many different networks from a variety of locations. Windows 8 makes mobile networking easier and more efficient by giving you better control over mobile broadband charges and by more intelligently connecting to your preferred Wi-Fi networks.
Mobile broadband
Windows 8 treats mobile broadband connections as metered connections. This behavior causes Windows to minimize the network traffic sent across mobile broadband connections, potentially reducing data charges. To further minimize mobile broadband usage and improve battery life, Windows 8 will automatically turn off your mobile broadband when a Wi-Fi hotspot is available. Wi-Fi hotspots usually have faster bandwidth, higher data caps, and lower latency. If you move away from the Wi-Fi hotspot, Windows 8 can automatically use your mobile broadband to reconnect to the Internet.
These improvements keep you connected while reducing your costs, maximizing your network performance, and increasing your battery life.
Windows 8 includes a new user interface for turning wireless interfaces on and off, as shown in. If your PC is equipped with mobile broadband, Windows will show a separate option on the same screen. You can use the new airplane mode to quickly turn all wireless signals off.
Wi-Fi
Windows 8 makes minor improvements to Wi-Fi behavior. If you manually disconnect from a Wi-Fi network, Windows 8 will stop automatically connecting to that network. If you disconnect from one Wi-Fi network and then connect to another, Windows 8 will configure the newly connected network at a higher priority so that Windows 8 automatically chooses that network in the future.
Windows 8 features connect more quickly to Wi-Fi networks when resuming from standby. Typically, Windows 8 can be connected to your preferred Wi-Fi network in about a second after resuming from standby. Windows 7 could often take more than 10 seconds.
