This should be very easy but I am finding it quite hard in Ubuntu.

I want to create a network so that I can connect other devices to my computer wirelessly. I do not need an internet connection, I just need an ad-hoc network from my Ubuntu computer which is running Gnome.

These directions are inaccurate, there is no "Use as a..." in step 4.

These directions imply that I can not change the automatically generated password for the Wi-Fi network. Also, see below, the network disappears after a few minutes.

The closest I have found is clicking the "hamburger nav" in settings and clicking "Turn On Wi-Fi hotspot" (pictured):

enter image description here

This does create an ad-hoc network but:

  • The name of the nework is fixed (can't change it)
  • The password is fixed (can't change it)
  • After about 20 seconds the hotspot menu (pictured below) goes away and I can't connect any devices to it even when it does appear.

enter image description here

Why is this so ghetto? I could do this on mac in about 10 seconds. How can I rename the ad-hoc network and how do I make it persist (i.e. not go anywhere)?

The output of dpkg -l *dnsmasq* is as follows:

| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name           Version      Architecture Description
un  dnsmasq        <none>       <none>       (no description available)
un  dnsmasq-base   <none>       <none>       (no description available)
  • Edit your question and show me dpkg -l *dnsmasq*. – heynnema Apr 29 '19 at 2:47
  • @heynnema I updated my question with the output of that command. – Startec Apr 29 '19 at 3:18
  • Is this a hot spot or ad hoc network? – ThatsRightJack May 11 at 4:04
  • @ThatsRightJack unsure what the difference is. – Startec May 11 at 5:14

Install dnsmasq-base. This should take care of your problem.

sudo apt-get update # update the software database

sudo apt-get install dnsmasq-base # install dnsmasq-base

  • That fixed it. I still can't set the password or network name (bummer) but now it stays open and I can connect. I have no idea why you knew that would fix it but thank you. – Startec Apr 29 '19 at 3:37
  • @Startec you're very welcome! – heynnema Apr 29 '19 at 3:38
  • I have this package installed, but when I create a Hotspot it does not go visible in any Android device I've tested... Any tip? – LEo Dec 11 '19 at 21:21
  • @LEo Does it work with non-Android devices? Did you try the next answer? – heynnema Dec 11 '19 at 21:25
  • @heynnema does this solution work for ad hoc or hot spot? – ThatsRightJack May 11 at 4:24

For connecting an Android tablet with bvnc, Ad-hoc is not the way to go. Instead, Right Click on the networkicon, and in the drop-down menu, select Edit connections/ under WI-FI tab, mode dropdown, select Infrastructure (instead of Ad-hoc), then under IPV4 settings, connection method, set it to shared with other computers. Then the Android tablet could see the network, and connect wirelessly.

  • where are these options. I don't see "Edit connections" anywhere under WI-FI tab, not any option for Ad-hoc (see above picture). – Startec Apr 29 '19 at 3:20
  • what does "shared with other computers" mean? What kinda network is that? – ThatsRightJack May 11 at 5:39
