So I have a ethernet connection and a 3G modem available. However at times my phones run out of battery due to the high power consumption that 4G data is. I want to convert my laptop into a Wi-Fi hotspot, so that my devices can connect to it, use the connection on it and save battery. I googled around for some software that would let me do that, but most of it was either malware or packed with some unwanted applications that I do not want on my machine. Tips, Ideas anyones?
