Network Manager regularly thinks my wifi is a wired device

Bug #1576215 reported by Mario Limonciello
This bug affects 22 people
Affects Status Importance Assigned to Milestone
network-manager (Ubuntu)

Bug Description

When I boot up my network doesn't automatically connect. I instead see when I click the network manager applet that it's got no Wifi devices listed. It thinks my wireless card is an ethernet device. This isn't true and I have no ethernet devices in my system.

When this situation happens if I issue /etc/init.d/network-manager restart it comes back up thinking it's a wireless device and happily associates with my saved SSID.

Yes, I confirmed that patch has resolved it for me. Tried it 10 times and didn't hit any failures. This patch is actually part of 1.2.0 which is being SRU'ed right now.

I backported that patch and manually tested a build with it applied. It will be fixed also by moving to the 1.2.0 release.

I can't seem to install NetworkManager-1.2.0

Just reported the same bug, i.e. dup.

Looks like current network manager in 16.04 contains "fix" from above,
but I still have this problem.

did a fresh install of 16.04 updated to NetworkManager 1.2.2 and this bug is definitely still there. restart network manager service fixes it.

I started having this problem after a regular package upgrade.
Ubuntu 16.04.1 LTS
Current Network Manager version in my system: 1.2.2

I hope it gets fixed in future versions. For now the workaround is to run "systemctl restart network-manager.service" after every reboot.

The bug is still exists. When my wifi connection is disconnected from the access point i.e the access point is restarted or its signals channel is changed, the network icon after re connect again turns to the two arrows Up/Down i.e like wired connection through the Ethernet. Also, my wifi link becomes unavailable in the network list in-spite of being connected to it, but other neighbors networks are still listed. i.e I could able to access my access point web interface through

I have the same problem too I have ubuntu 16.04 on a duo boot with Windows 8. Updated my ubuntu on 13/04/18 and now am no longer able to connect to my phone's hotspot which would connect automatically before.
Anytime it tries to connect it keeps asking for the password.
