WiFi networks list disappears (device type not reloaded)

Bug Description

If you are still experiencing this bug please don't comment here, but look at these: (https://goo.gl/LdPpYG)

Boot the system.

From time to time, some of these happen:
- The applet doesn't list any wireless network.
- The applet doesn't show the name of the current network.
- The icon shows the wired connection symbol, instead of the wifi one.


The applet needs to re-read the DEVTYPE after the device name changed.

In the Terminal application enter:
nmcli dev

If it works, in the line for the wireless device, the TYPE column should be "wifi". If it doesn't it will be "ethernet".

It does the same if the steps to reproduce (2) + (3) are replaced with suspend/wake up.

Is there any ETA for fixing this bug?

Cip Man (cipman-p) wrote :

ETA is with the release of Ballsy Baboon (i.e next ubuntu LTS - 18.04) :):)

Try disabling bluetooth if your system has it and you don't need it. Works for my laptop - now wifi works as it should on suspend or enable/disable wifi. If no luck, search askubuntu, there are some scripts that might fix this for your system.

MBWD (xmbwd) wrote :

This works to reset the wifi temporarily: `sudo systemctl restart network-manager.service`.

The scripts can help fix the wifi resume on suspend issues. However, I have not seen a script that fixes the inability to switch networks on an active wifi connection without it going dead.

Also, on a fresh install, I experienced a fourth problem:

4. Network manager creates a new instance of the network each time it connects to it (e.g., wifi_1; wifi_2; wifi_3. As a result, the user has to input a new password each time.

This bug caused me to roll back to 15.10. Hoping it gets fixed soon.

On my machine, the network connection resumes - if I do [nmcli g], I see that the network is connected. For me, the only issue is that the nm-applet reverts to the Ethernet setting (two arrows), and does not show the list of wireless networks available. Are we really going to have to wait TWO YEARS for a fix?

I installed 1.2 on my EeePC by enabling the Proposed repository in Software and Updates. This isn't usually recommended for everyone as it can break things, but is useful for testing.

Once the patched version is released and is moved from the Proposed to the regular repository, it will automatically be updated.

No dice. Returning from suspend no networks listed, wired or grayed wifi symbol but the network works.

Cip Man (cipman-p) wrote :

P.S. Just to be thorough, I also followed the 'Steps to reproduce' stated in the bug description and the results are the same as described in 'Problems'.

Perhaps you should also have updated network-manager-gnome package which contains the nm-applet.

I updated both network-manager and network-manager-gnome, then restarted both network-manager and nm-applet and now the problem is gone.

@Alan: network-manager-gnome was already at the latest version, the one mentioned by Robert above. But I also upgraded to everything xenial-proposed had 30 mins ago (thinking maybe you did that) and still no luck.

But this is how I made this version work for me (@Robert, maybe you'd like to test this?):
a. reboot (just to make sure we all start from the same point - I noticed it matters here)
b. open a terminal and $ sudo systemctl restart NetworkManager.service
c. test wifi off/on and suspend/resume - now NM works perfect for me (didn't test AP off/on as I can't do that now).
This workaround also works if between a. and b. you perfom c. to check if it works (which isn't for me).

I am on 16.04.1, and I too am having this issue. Whenever my laptop (W520) goes into Suspend or Hibernate mode and I boot it back up, the WiFi icon displays the "disconnected" message briefly, and then reconnects--only to display the up and down arrows associated with the Ethernet icon and the Ethernet drop-down menu in the top panel. No SSIDs are shown, and the menu asks me to connect to a WiFi network even though I'm already connected to one.

I have Thinkpad 11 bgn WiFi. Ubuntu displays it as "Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)". Device name is wlp3s0 rather than wlan0.

Same here Lenovo T530 Intel 6205 wifi adapter.
The work around (sudo systemctl restart network-manager.service) works for me most of the time. Sometimes my machine needs a reboot then a router reboot to reconnect. It's an old router but didn't present any issues before Ubuntu 16LTS install. Hopefully coincidental. Good luck!

I am pretty sure I'm having this problem on a Toshiba Chromebook 2 (CB35-B3340) running 16.04 fully updated as of this week. I get the ethernet up/down arrows, there is no ethernet on this laptop. I also get the state where it is disconnected and not showing any wifi networks. It seems to be related to suspend/wake, but doesn't always happen.

I am having this problem but in addition nm-applet is often gone from the notifications when my laptop wakes from suspend. I wonder if that is related. I fix it by doing a "killall nm-applet; nohup nm-applet &" but I would rather not have to.

This bug also affects my Toshiba Satellite C645 with a Qualcomm Atheros WiFi card and happens even if the connection is lost abruptly, like when there is a power outage and both the modem and the router shut down.

please solve the issue.

If you're seeing the wrong icon in nm-applet, please file *YOUR OWN* new bug report, and write the number here. Me-too's distract developers from being able to understand what the problem is, because many people have slightly different issues that all look similar.

As we understand it, the original bug is fixed, where wireless would be detected as wired on boot. That means it would show the arrows icon, but my other issues can lead to the icon being wrong.

Unless you run 'nmcli dev' and see that the wireless device says "ethernet" beside its name, then you are not seeing this here bug and should open a new bug report.

If you run 'nmcli dev', and you have wireless that is connected, but also wired or some other network device connected and you see the arrows, then it *might* be expected behavior. Wired networks always take precedence over wireless if both are connected. If you still think it's wrong, please file a new bug, and include the output of 'nmcli dev' and 'ip route'.

Ubuntu 16.04 on dell E6430, after upgrade:

- 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...

a problem with the /dev/something, no?

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

This bug is still present in Ubuntu 16.10! Do you know if other desktop distributions like Fedora or openSUSE also have this bug?

Peter Amaral (amaralpeter) wrote :

Hi everybody, I realize that this fix I found may not help everybody. However, the symptoms I was seeing are the same as described in this bug report so maybe it will work for some other folks as well. The solution was to do the following:

$ sudo vim /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Change the value of wifi.powersave to 0


After rebooting I have not experienced the problems with disconnect, even after resuming from suspend.

As I understand it, this setting will disable power management for wifi adapters if its not supported in the driver/kernel by default.

larabi: I came from Fedora, and I had been running it for the last releases on my laptop. Never had any WiFi issues, so there's not anything wrong with my hardware. I recently installed Ubuntu 16.04.1 LTS, but these WiFi issues are quite annoying and I'm contemplating switching back to Fedora. I don't understand how this still hasn't been fixed in an LTS version of the OS.

The "HOW TO TEST A FIX" is meaningless.

nmcli dev

wlp2s0 wifi connected Thomson_etc

but the applet still doesn't list any wireless network.

@ Stavros Daliakopoulos

That simply means this report isn't related with your bug. Even when the consequences are the same, the causes aren't.

If i set "All users may connect to this network" in 'network connections'for the used wi-fi connection, nm-applet does no longer crash when returning from suspend?

I can't confirm. unfortunately this doesn't do the trick for me.
What's different now is that the WiFi is already conected on the login screen with the arrow icon. As soon as I login, it's the WiFi icon. When I suspend and return I have arrows again.
