I bind my netbook to my PC having a broadband Internet connection and check the option to use the PC for networking. I then open the NetworkManager applet menu and see the connection created. But it's not useable as I click to connect.
I tried it several times with same result.
Steps to Reproduce:
1. Bind a notebook to a PC having a USB bluetooth dongle installed;
2. Choose the newly created Internet connection in the NetworkManager applet.
The NetworkManager icon twirls for a while showing it is working on the command, but then goes back to "disconnected". No connection actually established. When doing same action with a mobile phone it connects well and changes its icon to "wireless connection".
I have also tried to do the same with Blueman and it also failed saying "Failed to obtain an IP address on bnep0". I'm not sure if it's related, though, as these are different software.
I have googled for the error message, but it seems to be a rare issue. I have also asked on IRC, but I assume noone got interested to answer.
Sorry, couldn't post it several times.
