Ubuntu – Cannot make Wi-Fi hotspot

11.10laptopwireless

I want to make my laptop as wi-fi hotspot. To do so, I pressed button Settings->Network->Wireless->Use as Hotspot..

Then it creates a wireless network connection 'Hostspot' and connects. But it gets disconnected just after making connection.

Here is my network hardware info:

sudo lshw -C network
  *-network

My machine is running on Ubuntu 11.10

Can anybody help in it?

Thanks

I had the same issue. I have found a report that has already been registered. There is a suggested workaround that works for me:

  1. go to System settings > Network > Wireless > Use as hotspot > Configure (or 'Edit connections' under your connections > Edit the hotspot connection)
  2. Switch to IPv6 Settings tab > Set Method to 'Ignore' and confirm/save
  3. in terminal (Ctrl + Alt + T) run the following command to kill all dnsmasq processes: sudo killall dnsmasq

  4. go to System settings > Network > Wireless > Use as hotspot

Should work, and I have set my hotspot up as it is in the Mosture's post

Edit: I needed to set up android accessible hotspot recently, and I was successful in creating such through ap-hotspot.
