Network Manager set DNS wrong for GSM network

[Jouston Huang]

sdfDescription: Ubuntu 8.04.1
Release: 8.04

I am using network-manager-0.7~~svn20080908t183521+eni0-0ubuntu4~nm1~hardy1. With my Huawei E169 HSDPA modem I always have my /etc/resolve.conf set to the DNS gain from eth0.

Then I figure out that the eth0 was automatically setup as "system setting". Only after I uncheck that "system setting" my /etc/resolve.conf back to right setting.

This is an usability issue. People would not know their other wireless network or GSM network can't override the DNS setting.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

Until today (3/3/09) I was using Intrepid. I plug in my Huawei E169 and it happily connects and changes to the appropriate DNS for my 3G provider. In Intrepid I had updates, proposed and backports enabled.

Now I have upgraded to Jaunty and the DNS settings are not updated when I insert the E169, it is still using the DNS from the ethernet connection - now unplugged. I had to go into the settings of the Mobile Broadband connection and edit the config and add the correct DNS addresses. It now works fine and survives reboots. This appears to match the above bug.

I had no issue in Intrepid, but the bug has reappeared in Jaunty. I have replicated this issue on another laptop that I upgraded to Jaunty and then reverted to Intrepid for other reasons.

thanks
