I have this bug as well in a clean MATE 16.04 install. x220, Intel 6205 wireless . Using the firmware iwlwifi 18.168.6.1
Various things like #12 sudo iwlist wlan0 scan - does not work for me. Also disabling Wireless and/or networking via Network Manager - and re- enabling does nothing. Nor does using hardware on/off/on for wifi make a difference. Rebooting fixes it. I have tried this fix http://ubuntuforums.org/showthread.php?t=1984317&page=3 [which is a seperate fix for the Intel Wireless hardware flaky WiFi connection - not related I feel] Subsequently I have gone back to 14.04 MATE and works perfectly! Is this a systemd issue perhaps? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448555 Title: network-manager does not autoconnect to wifi network after resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1448555/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
