Updater applet erratic behavior in opensuse 11.2

Hi, I just installed opensuse 11.2 in my computer and I’m having problems with the updater applet. My internet works fine but the updater applet (using PackageKit plugin) doesn’t work. It keeps showing the error:

PackageKit Error no-network: Cannot refresh cache whilst offline

If I start Yast to try to update manually (as it suggests) the following error occurs:

Download failed:
Failed to download /repodata/repomd.xml from …

It happens with all repositories regardless.

The /etc/PackageKit/PackageKit.conf file says it uses NetworkManager (UseNetworkManager=true) but it’s not listed among the running processes. If I launch NetworkManager manually from command line, the updater applet says it can’t check whether updates are available and ask me to connect to the Internet. After a while, it starts to check for updates normally.

If I change the plugin (before launching NetworkManager) to ZyppPlugin something similar happens but the update applet error this time is:

Refresh failed. Please run ‘zypper refresh’ as user root.

My question is: what do I do to make the applet work right away without having to launch NetworkManager manually?
