I'm running Ubuntu 12.04 as a virtual machine on my Mac. Since I am unable to get the virtual machine to have full access to my WiFi card, I bought another USB WiFi card to use.

This is my WiFi card.

If you are unfamiliar with Virtual machine, as far as I know, since the Ubuntu has its own card now, it shouldn't matter.

I have followed these guides with no luck:

The problem is that the WiFi connection appears on all of the machines that I have in my house: 2 iPhones, Dell machine running Ubuntu and two Macbooks. However the connection times out on all of these machines.


  1. Could this be a driver issue if that same WiFi card can connect to other WiFi points and use its internet
  2. Could this be DHCP related? I would think not. It should at least get a 169.X.X.X address? No?
  3. Any solutions for me?
  • Sorry to jump on the "me too" but this affects me too- I'd love to be able to get the ad-hoc wireless network up and running from my Ubuntu installation! – Bill O'Dwyer Aug 17 '12 at 3:35

    Well, let me know if you wanna work on this together. If you want, you can jump on irc freenode room #joubin and we can hammer it our together. (IE compare notes/errors) L – user1048138 Aug 17 '12 at 7:30
  • does your Wi-fi card support AP & Master mode? The link u have posted giving sql-database error. Any way, first type sudo iwconfig, this should list all available wireless interfaces. sudo iwconfig wlan1 mode master & replace wlan1 with your interface. – Khurshid Alam Nov 20 '12 at 5:30
  • Also you need to check what kernel driver you are using.To do this first type lspci | grep -i wireless. Take the first number it prints & type: lspci -vv -s 03:00.0 replace 03:00.0 with ur number. At the end of the output it wiil show something like this Kernel modules: ath9k. This means your kaernel driver is ath9k. You can type modinfo ath9k.This again produces lots of information which may require for debugging. – Khurshid Alam Nov 20 '12 at 5:41
  • There is depends: section which shows something like this :depends: ath9k_hw,mac80211,led-class,ath,cfg80211,ath9k_common. nl80211/cfg80211 (most new drivers) are well supported by linux. – Khurshid Alam Nov 20 '12 at 5:47

The blog you are following doesn't list general steps of setting up wifi-ap with hostapd. For 12.04 more complete step by step details can be found here:


The detailed step-by-step answer is already posted here at Ask-Ubuntu:

How to setup a wi-fi hotspot (access point mode)?.


You can check by opening addtional drivers in dash whether it is need or not. If your system missing it , it will automatically indicate it and suggest to install.

According to me , It may problem of DHCP server , Configure your router dhcp , give long lease time in configuration options.


On W8 website there is a new script for this purposes, very easy and comfortable.


Working good on my laptop.
