With the increasing number of portable devices like laptops, tablets and music players we need to be connected to the Internet constantly. Wi-Fi routers are good at keeping all these devices online, but things become tough when you are on the move. You always have the option of buying a data dongle or a portable Wi-Fi hotspot. Alteratively, if you own the latest Android or Windows smartphone, you can use the phone’s data connection to create a secure Wi-Fi network of your own. This option is available in your settings menu as “Wi-Fi hotspot, Internet tethering or Internet sharing”. You can secure this network with a password and connect up to five devices to surf the Net. In the US and some other countries, operators have special plans for Internet tethering. But thankfully, Indian carriers don’t charge extra for mobile hotspots.
