back to suggestion #12: It does not fire (still don't know why)
However, running iwlist scan (as sudo) DOES reconnect. Today I connected to another network (which I use regulary. The connection was established immediately after resume. After putting the machine to sleep again, no reconnect occured after resume. Thus my observation: If after wake-up the network environment is the same, network manager DOES NOT reconnect. If after wake-up the network is different (other SSIDs or SSID not found) a scan is launched automatically and a reconnect occurs. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1448555 Title: network-manager does not autoconnect to wifi network after resume from suspend Status in network-manager package in Ubuntu: Confirmed Bug description: After upgrading to 15.04 network manager does not reconnect to the wifi network after resuming from a suspend to memory.
