I am connected to a WiFi network but wired connection icon is shown:

Screen-shot of the problem:

I also can't see other available WiFi networks in order to connect to them.

Output for lspci -knn | grep Net -A2:

0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
    Subsystem: Dell Wireless 1397 WLAN Mini-Card [1028:000c]
    Kernel driver in use: wl

What should I do?

    +1 very strange indeed. And I also notice it doesn't show you the list of SSIDs...

  • Also when I disable then re-enable wifi, it shows the wifi icon trying to connect to the saved network. But when it's connected, wired network connection is shown.

  • What WiFi hardware do you have ? You can check with lspci -knn | grep Net -A2.

    Bug persists in ubuntu 16.10. After suspend, network manager thinks I'm connected via wire. However, if I go to system-settings -> network I can see the list of nearby SSIDs and confirm the fact that I'm connected to the correct network.

This is caused by a bug in Network Manager. It seems that when wlan0 is renamed using the new naming scheme it confuses Network Manager and Network Manager thinks you have another ethernet connection.

It can normally be fixed with 

systemctl restart NetworkManager.service
The command will have to be done after a reboot or suspend until the fixes are released

    Is it possible by changing the interface name?

    And it looks like the bug has been fixed. Probably the system needs to be updated.

  • It looks like b43 should be used with this adapter insted of wl.

I changed my WiFi driver to rtlwifi_new, and it seems to have solved the issue. I get the normal WiFi icon when I suspend my computer now. Thank goodness!

  • What OS are you using @UnityLauncherProblems ? I'm curious about using this driver, but would be hesitant unless I knew more about it. I found it on GitHub (github.com/lwfinger/rtlwifi_new), but otherwise am not sure about its use...
