How to connect android wifi to adhoc wifi

Question

I m new on the android system  Is this correct  the android 2 2 1 WIFI only detects non-ad hoc wireless network  I was wondering if there s a way to connect my android to an ad hoc network set-up from my laptop

If you specifically want to use an ad hoc wireless network  then Andy s answer seems to be your only option  However  if you just want to share your laptop s internet connection via Wi-fi using any means necessary  then you have at least two more options    Use your laptop as a router to create a wifi hotspot using Virtual Router or Connectify  A nice set of instructions can be found here  Use the Wi-fi Direct protocol which creates a direct connection between any devices that support it  although with Android devices support is limited  and with Windows the feature seems likely to be Windows 8 only     Some phones with Android 2 3 have proprietary OS extensions that enable Wi-fi Direct  mostly newer Samsung phones   but Android 4 should fully support this  source

You are correct that this is currently not natively supported in Android  although Google has been saying it will be coming ever since Android was officially launched   While not natively supported  the hardware on every android device released to date do support it  It is just disabled in software  and you would need to enable it in order to use these features     It is however  fairly easy to do this  but you need to be root  and the specifics may be slightly different between different devices  Your best source for more informationa about this  would be XDA developers  http   forum xda-developers com forumdisplay php f 564  Most of the existing solutions are based on replacing wpa supplicant  and is the method I would recommend if possible on your device  For more details  see http   szym net 2010 12 adhoc-wifi-in-android    Update  Its been a few years now  and whenever I need an ad hoc network connection on my phone I use CyanogenMod  It gives you both programmatic and scripted access to these functions  and the ability to create ad hoc  ibss  networks in the WiFi settings menu

If you have a Microsoft Virtual WiFi Miniport Adapter as one of the available network adapters  you may do the following    Run Windows Command Processor  cmd  as Administrator Type  netsh wlan set hostednetwork mode allow ssid NAME key PASSWORD Then  netsh wlan start hostednetwork Open  Control Panel Network and Internet Network Connections  Right-click on your active network adapter  the one that you use to connect on the internet  and then click Properties Then open Sharing tab Check  Allow other network users to connect     and select your WiFi Miniport Adapter Once finished  type  netsh wlan stop hostednetwork   That s it   Source  How to connect android phone to an ad-hoc network without softwares

You are correct  but note that you can do it the other way around - use Android Wifi tethering that sets up the phone as a base station and connect to said base station from the laptop
