Here are the command outputs after a suspend/resume. This time I was lucky and the wifi came back after restarting NetworkManager:

I'm also attaching a kern.log from the last hour. I noticed in there that there was a Call Trace from the time when NetowrkManager would not restart the network and I had to reboot. It's probably worth look at that. -- 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/1635907 Title: Can't connect to Wifi network after suspend and resume Status in network-manager package in Ubuntu: New Bug description: Beginning in Ubuntu 16.04 and getting worse after upgrading to 16.10, I can't connect to wifi networks after suspending and resuming my laptop. I have a Sony Vaio SVP112A1CL with wireless network controller Intel Corporation Wireless 7260 (rev 6b). Typically I have to restart NetworkManager to recover from the problem (sudo systemctl restart NetworkManager). This seemed to be a reliable way to recover in 16.04, but it doesn't always work in 16.10 and may require a reboot. In some related bug reports they requested we run `sudo iw dev wlan0 scan` which resulted initially in an error but after running it a few times returned successfully. I'll attach the output below. Even though it did return, the wifi network still was unable to reconnect. I'll try to grab the errors next time, but if I do it now, I'll lose connectivity. $ apt-cache policy network-manager network-manager: Installed: 1.2.4-0ubuntu1 Candidate: 1.2.4-0ubuntu1 Version table: *** 1.2.4-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu yakkety/main amd64 Packages 100 /var/lib/dpkg/status $ sudo iw dev wlan0 scan BSS d4:05:98:46:d9:40(on wlan0) -- associated TSF: 2690064842954 usec (31d, 03:14:24) freq: 2457 beacon interval: 100 TUs capability: ESS Privacy ShortPreamble ShortSlotTime APSD (0x0c31) signal: -68.00 dBm last seen: 3728 ms ago Information elements from Probe Response frame: SSID: stevens-2G Supported rates: 1.0* 2.0* 5.5* 11.0* 9.0 18.0 36.0 54.0 DS Parameter set: channel 10 ERP: <no flags> Extended supported rates: 6.0 12.0 24.0 48.0 Country: US Environment: Indoor/Outdoor Channels [1 -
