I have installed ubuntu hardy heron on my pc recently and have not been able to get the internet working. I have an awlh3025 by airlink. I put my settings in, i.e. passphrase, type of security (WPA), but it still doesn't work. Also after these attempts I shut my computer off and the next time I turn it back on again, it didn't start correctly and while booting it stopped and said:
"Starting Avahi mDNS/DNS-SD daemon avahi-daemon [FAIL]
Timeout reached while waiting for return value
Could not receive return value from daemon process."
Eventually it skips this and completes booting, however after I enter my username and password, and am logging in, a window pops up saying,
"There was an error starting the GNOME setting daemon

Some things such as themes, sounds, or background settings may not work correctly.

The last error was.

Did not receive a reply possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply. The reply timeout expired, or the network connection was broken.

GNOME will still try to restart the settings daemon next time you log on."

if any one could help it would be greatly appreciated...

Avahi ARP-spams your network checking for available resources like 'puters, printers 'n stuff. If you find you don't need Avahi you can disable it. Else the the first thing to get running would be your network connection. If you need help with fixing your Airlink AWLH3025 -> http://acx100.sourceforge.net/wiki/Device_list#AWLH3025 -> ACX111 driver -> http://acx100.sourceforge.net/wiki/ACX HOWTO and if any questions open a thread in the Wireless forum, a sub of the LQ Networking forum.
