Ubuntu 16.04 on dell E6430, after upgrade:
- after suspend/resume sometimes the network manager cannot connect (but it
tries: it keeps associating/de-associating) [before upgrade, the wifi was
broken at this stage, cf below]
dmesg:
[101381.710749] wlan0: authenticate with 42:01:40:59:9f:3c
[101381.712600] wlan0: send auth to 42:01:40:59:9f:3c (try 1/3)

[101388.104512] cfg80211: (start_freq - end_freq @ bandwidth),
(max_antenna_gain, max_eirp), (dfs_cac_time)
- if I deactivate and then reactivate the wifi, then it reverts to the old bug
(where there is only one network available and nothing happens). sudo service
network-manager restart repairs everything...
The bug is still at this point:
[101418.822530] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
[101418.869145] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

[101426.442267] iwlwifi :03:00.0: Radio type=0x0-0x3-0x1
a problem with the /dev/something, no?
strange...
hope this can be repaired soon. But also in the 14.04 distrib it was sometimes
necessary to deactivate/restart the network manager to catch back the signal
after resume...
good luck, thanks

Title:
[SRU] Re-read the link type if the name changed
Status in NetworkManager:
Fix Released
Status in OEM Priority Project:
Fix Released
Status in network-manager package in Ubuntu:
Fix Released
Status in network-manager source package in Xenial:

Bug description:
[Impact]
NM needs to re-read the DEVTYPE after the device name changed, an example is
that WiFi network list disappears from network manager applet
[Testcase]
1. Boot the system. It should include a wireless device.
2. In a terminal, run 'nmcli dev'.
3. In the correct case, the line for the wireless device should read "wifi"
under the TYPE column. In a failure case, it will read "ethernet".
After upgrading to the new version, the repeating the above steps
should give expected behavior.
[Regression Potential]
Potential of causing regression is relatively small for a one line change to
re-read a value to be known.
---
Problems:-
1. The network manager applet does not show the list of WiFI APs it can find.
2. The network manager applet does not the name of the AP to which it is
connected
3. The icon of the applet shows two vertical arrows in opposite direction -
the wired connection symbol and NOT the wifi connected icon.
Temporary Workaround:-
Log out and again log back in.
