I just installed ubuntu 16.04. I have the problem that wifi cannot reconnect in any way after a long time sleep or suspend or hibernate( I leave the computer until next day ).
I googled, I've tried any method I can find online, but they don't work:
I followed this thread, edit the /etc/NetworkManager/NetworkManager.conf, but it's not working
this thread, run the command:
systemctl restart network-manager.service
sudo killall NetworkManager && sudo NetworkManager
- $ sudo nmcli networking off
$ sudo nmcli networking on
- $ sudo ifdown -a
$ sudo ifup -a
- sudo ifconfig wlp4s0 up
service network-manager restart
I don't know whether my problem is caused by this bug, but I don't see the fix for this bug: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1574347
nmcli dev shows that the type is wifi, but it is disconnect, I can't make it reconnect except reboot system.
Can someone help me?
