Android phones - Click Settings, select "Wireless & Networks", then touch to click the box next to "Portable Wi-Fi hotspot".
Once devices are connected to the hotspot, browsing the Internet is the same as when connected to any other network. Using a smartphone as a wireless hotspot can be extremely helpful when another wireless network is not present, or when only free public access is available. Free public wifi access is fine for general web browsing, but for online banking, or using account credentials, utilizing a secure hotspot is a safer way to connect to the Internet. Lastly, remember to disconnect devices from the hotspot when you no longer need it, as well as turning off the hotspot feature on the smartphone.
Good luck and happy browsing!
