Hostapd : The Linux Way to create Virtual Wifi Access Point

NOTE: Although this guide should work in most cases, it is not flawless and still requires few minor modifications to make the process bug-free. Please do point out corrections and changes.

I was recently looking into ways to use my laptop’s wifi adapter as a wireless access point to enable my phone (Nokia E63) and playstation portable to connect to the internet through it. Ad-hoc feature may be used to share internet through wifi, but it doesn’t work with many phones and my PSP. I found connectify and virtual router for Windows which served this purpose, unsatisfactorily.

Both the programs offered only WPA2-PSK encryption for infrastructure mode and WEP and open encryption for ad-hoc modes. Many devices connect only through infrastructure mode and support for WPA2-PSK is absent in few devices (including the PSP). Also, since I am a Linux user, I needed something else.

This is where hostapd kicks in.
