Tried to set up DHCP server on my Dell Inspiron desktop (Ubuntu 14.04 installed) but doesn't seem to work. So I'm trying to manually input static IP address, DNS info etc into the ipad directly, but it tells me that while I can connect to the network, the network is not connected to the internet. And my network only shows up under "devices" and not under "choose a network". Any suggestions greatly appreciated. cheers

The default Ubuntu hotspot is not recognised by Android devices and probably not by the IPAD too. So, try installing ap-hotspot in Ubuntu. Open terminal and type the following,

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install ap-hotspot

For 14.04, you need to uninstall the buggy hostapd

sudo apt-get remove hostapd

Then install the needed version - for 64 bit systems:

cd /tmp
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/w/wpa/hostapd_1.0-3ubuntu2.1_amd64.deb
sudo dpkg -i hostapd*.deb
sudo apt-mark hold hostapd

and for 32 bit systems:

cd /tmp
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/w/wpa/hostapd_1.0-3ubuntu2.1_i386.deb
sudo dpkg -i hostapd*.deb
sudo apt-mark hold hostapd

Now ap-hotspot is installed.

To configure, type 

sudo ap-hotspot configure

Enter the appropriate interfaces, the hotspot name and password. To start the hotspot, type sudo ap-hotspot start

and to stop,

sudo ap-hotspot stop

Hope it helped!

  • Thanks for the help. Typed in "cd /tmp && wget http://archive.ubuntu.com/ubuntu/pool/universe/w/wpa/hostapd_1.0-3ubuntu2.1_amd64.deb && sudo dpkg -i hostapd.deb && sudo apt-mark hold hostapd" and got "404 not found". Also got a fail message earlier on; " Starting DNS forwarder and DHCP server dnsmasq
    dnsmasq: failed to create listening socket for 10.42.0.1: Address already in use". Should I have removed the DHCP server first?     – kokuraMike Jun 22 '15 at 14:27
  • Did first three steps work? Then, try sudo ap-hotspot configure – spharish Jun 22 '15 at 14:34
  • The first 3 steps worked. The step for 64 bit systems returned a 404 not found error. And when I tried to configure ap-hotspot I got "sudo: ap-hotspot: command not found" – kokuraMike Jun 23 '15 at 04:21
  • did sudo apt-get remove hostapd work? and yes, try removing the previously created DHCP server – spharish Jun 23 '15 at 06:55
  • It seems I was able to remove the DHCP server. Then I did your first 3 steps again (no problems) and removed the hostapd. But the next step for 64 bit systems ends with a 404 not found. Here is the terminal: – kokuraMike Jun 23 '15 at 13:21

  • @kokuraMike You have said you have removed hostapd, then try the following steps one by one: – spharish Jun 23 '15 at 16:13

    cd /tmp, then wget http://old-releases.ubuntu.com/ubuntu/pool/universe/w/wpa/hostapd_1.0-3ubuntu2.1_amd64.deb, after that, sudo dpkg -i hostapd*.deb, finally sudo apt-mark hold hostapd – spharish Jun 23 '15 at 16:15
  • The above can work because we are downloading from old-releases.ubuntu.com – spharish Jun 23 '15 at 16:17
  • @spharish I just encountered the 404 issue trying to set up ap-hotspot, and forgot old stuff gets move to the old-releases server - thanks! N.B. using the old version of hostapd that ap-hotspot needs may be a massive security risk.... – Wilf Jun 24 '15 at 16:20
  • I really appreciate all your help, but I'm still getting a 404 not found error. Is the fact I live in Japan a problem somehow? – kokuraMike Jun 25 '15 at 10:31
  • The answer is edited now, do you mean you are getting the same error now also, after doing everything from first? @kokuraMike – spharish Jun 25 '15 at 12:04
  • Yes. So I went to the "old-releases.ubuntu.com/ubuntu/pool/universe/w/wpa/…" site in my web browser and installed the software from there, but the terminal says "dpkg: error processing archive hostapd.deb, (--install): cannot access archive: No such file or directory Errors were encountered while processing: hostapd.deb" when I type in " sudo dpkg -i hostapd*.deb". – kokuraMike Jun 25 '15 at 22:57
  • @Wilf do you have any solution for the above problem? – spharish Jun 26 '15 at 07:03

    Try using the command (not a browser) to download the package from the old-releases URL (I updated the commands in the answer), but specify the package name - e.g. for 64bit: wget http://old-releases.ubuntu.com/ubuntu/pool/universe/w/wpa/hostapd_1.0-3ubuntu2.1_amd64.deb && sudo dpkg -i hostapd_1.0-3ubuntu2.1_amd64.deb. If you need help working out whether you have 32bit or 64bit, use http://askubuntu.com/questions/41332/how-do-i-check-if-i-have-a-32-bit-or-a-64-bit-os . You may need to reinstall ap-hotspot if you used sudo apt-get remove hostapd. – Wilf Jun 26 '15 at 12:04
