Ubuntu lets you easily create a wireless hotspot by using the Network Manager, but it uses an ad hoc network and most Android and Windows Phone devices can’t connect to such networks.For this reason, I’ve created (in collaboration with Satya) a script called AP-Hotspot that automatically creates an infrastructure (Access Point mode) wireless hotspot in Ubuntu that should work with Android and Windows Phone devices. The script uses hostapd and dnsmasq and it requires Access Point mode support for your wireless card – AP-Hotspot checks for this automatically and won’t run if your wireless card doesn’t support it.So far, we’ve tested it with a Dell Inspiron 1545 (Wireless Card: Broadcom Corporation: BCM4312 802.11b/g LP-PHY) and a Dell XPS L702X (Wireless: Centrino Wireless-N 1030) and the Android devices we’ve used have successfully connected to the Wi-Fi hotspot, unlike using the Ubuntu built-in hotspot feature. Because this depends on the hardware you’re using, it isn’t something easy to test and it may not work for everybody but hopefully it will work for most configurations.AP-Hotspot is based on THESE instructions (which by the way, you can use if you don’t
