The temporary fix is to delete resolve.conf, connect to a different network (since the new NetworkManager doesn't allow reconnecting to the same network), then connecting to the intended network. No pattern relative to Wired or Wireless. Reproducible: Sometimes Steps to Reproduce: 1.connect to different DHCP networks 2. 3. Actual Results: sometimes cannot resolve hostnames/websites since resolve.conf is not correct for current network Expected Results: rewritten resolve.conf Easy to fix for a technical user however would be considered broken for a non-techie. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

regards, Carlos The NetworkManager use dhclient to got the DHCP configuration. After you delete the resolv.conf do you still reproduce this issue?

If so, could you kill your NetworkManager and run 'NetworkManager --no-deamon' in a terminal, then try to reproduce this issue, after the dhcp finish it'll show the ip address and DNS information. After that it'll update the DNS to resolv.conf by netconfig. Do you find some error? Or just attach you terminal's log here.

Funny thing was... i could not reproduce the issue for a few days - everything worked fine. I'd been doing the "dhcpcd wlan0" for weeks perhaps without needing to do so. However, i was only switching between my home and work wifi. Since then I've connected to other networks and the problem as arisen again. I've attached my /var/log/Networkmanager file. I'll try and do what you proposed bellow. regards, Carlos (In reply to comment #4)
