In 2017 It seams there's some problem with network-manager and also power management in the driver.
Workaround: Don't use network-manager. I'm using trinity, with out network-manager. I also deactivated power management for wifi, and it works correctly. sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf change "wifi.powersave = 3" to "wifi.powersave = 2" don't forget to save :P .... then restart the network, or just reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1393744 Title: 1814:0301 RT2x00/rt61pci disconnects since update to 15.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1393744/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
