also with my laptop after upgrading from 14.04 to 16.04. I had another problem already in 14.04 with wifi device driver when it used to drop link some time after not being used - I had to use RF key on keyboard to make it up again. But back to this bug...
Following happened: 1. 14.04 -> 16.04 upgrade updates my machine 2. using 16.04 good after that 3. the WLAN built-in device drops and machine is shutdown 4. the Ubuntu OS couldn't but the device up anymore 5. So I tried resolving my WLAN status hitting many times radio switch on keyboard, and also without success to enable it in NetworkManager, these activities in the system just didn't make the built-in device up so ... 6. I removed laptop battery, no difference 7. entered BIOS, reset defaults and WLAN device was back in Ubuntu. 8. Now in 16.04 everything is back as in 14.04 (also the other problem which I believe is some driver issue unrelated to this bug) This just might sound crazy but my assumption is that the upgrade and shutdown while built-in WLAN was disabled in RF was the reason for the WLAN device not to come up again after boot just by pressing the RF key on keyboard. I can't make the difference between hardware and software blocking when it comes to RF key on keyboard. I believe it's software blocked when you do it with the keyboard (?) But why WLAN got disabled in BIOS and why RF key press did not bring it up anymore in 16.04? I would not be writing here if I had any doubt that after the upgrade someone came in middle, entered BIOS and disabled WLAN in BIOS. Writing comment because this bug seemed to affect me also. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1613437 Title: RT3290 Wifi stopped working after upgrade from 14.04 LTS to 16.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1613437/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
