I use an application called connectify to turn my laptop to a wifi router and provide other devices with internet using my DSL connection. But after I switched to Ubuntu 11.10 I can't use this any more. Is there any Linux software or trick available to do this?

yes, Ubuntu and many of it's flavors have feature called "ad-hoc network" and "wifi tethering"

To make wifie hotspot, you need to have some connection (cable connection, or another wifi connection (that woudl require a second wifi adapter).

Remember, you can't use the same adapter as WiFi receiver and wifi spot.

Go to network settings -> Edit Connections -> Wireless -> Add. Create a new connection and select Ad-hoc in Mode you can specify a password and enjoy.

  • Are these instructions complete? Don't you need to enable sharing as well? Feb 19, 2012 at 13:53
  • @MariusGedminas no you don't need.Ad-hoc means sharing

    You mean Network Manager automatically enables IP forwarding and sets up NAT as soon as you create an Ad-hoc connection? I didn't know that. (I'm not sure I believe it, either ;) Feb 19, 2012 at 15:43

    @MariusGedminas yes! I worked like that already. I didn't set any routing, NAT or any forwarding, masquerades.

there is bug currently in Ubuntu so there is work around for making ad hoc wifi access point, queting bellow:

"connecting with shared with other computers connection in NetworkManager. Other computer gets IP but NetworkManager disconnects the shared connection after half a second. This same setup worked perfectly fine in 11.04. Is there any fix, workaround or alternative way to share a connection with another computer over an Ethernet cable. (I can downgrade to 11.04 but I'd rather not ).

EDIT: found a workaround The workaround for now is to set IPv6 options to Ignore and then sudo killall dnsmasq. Reconnect and it should work."

I done it on my laptop with Ubuntu 12.04 and mine working fine now.
