Public bug reported: I can't connect to my wi-fi with my laptop.
I get this error message in the syslog. Apr 8 22:25:35 ubuntu kernel: [ 793.895555] wlan0: authentication with 10:bf:48:e5:d1:b8 timed out ubuntu@ubuntu:~$ lshw -c network WARNING: you should run this program as super-user. *-network description: Ethernet interface product: Ethernet Connection I217-V vendor: Intel Corporation physical id: 19 bus info: pci@0000:00:19.0 logical name: eth0 version: 05 serial: 00:90:f5:f8:ef:86 size: 1Gbit/s capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e1000e driverversion=2.3.2-k duplex=full firmware=0.12-3 ip=192.168.2.208 latency=0 link=yes multicast=yes port=twisted pair speed=1Gbit/s resources: irq:29 memory:f7e00000-f7e1ffff memory:f7e3d000-f7e3dfff ioport:f080(size=32) *-network description: Wireless interface product: Wireless 3160 vendor: Intel Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: wlan0 version: 83 serial: a0:88:69:39:ae:d6 width: 64 bits clock: 33MHz capabilities: bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.19.0-10-generic firmware=25.15.12.0 latency=0 link=no multicast=yes wireless=IEEE 802.11abgn resources: irq:32 memory:f7c00000-f7c01fff Attached is the full syslog. This machine has been working more or less ok on vivid for at least three months. Sometimes it refused to connect to the wi-fi, but after a restart it started working. Recently I changed the network from N to G, and recently did an upgrade to the latest vivid. I had some problems booting, so I also recently fully removed upstart. It boots fine with systemd, and everything else seem to be working. I've just tested with a daily vivid live USB, and the same problem happened. I'm connecting to the same network using the same password with my other machine.
