Comment 84 for bug 40125

After looking at the last attached nm.log, I would ask if:
Could it be, that in IFRFlyer case, nm-applet and not NM is irritated? As far the log says, the first DHCP request after resuming fails, then a 2nd is attempted and successful!
I would say there should be network connectivity and only nm-applet is wrong saying 'No network inferface detected'. This would match the dbus problem with max_replies_per_connection, where nm-applet doesn't get a list of network interfaces after resuming.

IFRFlyer - could you please re-check your NetworkManager.conf with the one attached to this report? Please try once more
- run NetworkManager --no-daemon 2>&1 | tee nm.log
- suspend / wait a litte / resume
- look at the nm output for sucessful configuration (stage 5 completed, wpa_supplicant ASSOCIATED, ....)
- check configuration in another terminal with ifconfig
- restart nm-applet, if necessary
