want to share my Laptops (running Ubuntu 10.10) Broadband with my Android (Galaxy Mini) running 2.2.1. Since Androids currently do not support ad-hoc networks so the "Create new wireless network.." won't help.

Q1) How do i setup a Wireless Access Point using my Laptops WiFi card? Q2) What is the difference between an "ad-hoc" network and an "access point"?

Not all wireless cards support Access Point mode. Check to make sure your card does, before you frustrate yourself in software.

OpenWRT uses hostapd to provide its services. It is available for Utuntu.

You will need to arrange for masquerading and firewalling as well. I like Shorewall for things like that. In your case the two-interface model should work well.

Thanks for reply. Any method to backup my current network configuration so that if i screw-up i may be able to revert to my original settings :P –  Abdul Karim Memon Apr 17 '11 at 14:13
    
@Abdul: If you are using /etc/network/interfaces, then you can just copy it. If you are using NetworkManager, your configuration should be in the /etc/NetworkManager directory tree. I think the system-connections directory will have your configuration. –  BillThor Apr 17 '11 at 17:03
