Ubuntu 16.04 on a Lenovo Ideapad Y560. The wifi automatically connects upon startup to the network I've been using, which is good. However, I can't find a way to display other networks that are in range.

Is this just how the Unity GUI works - there's no way to select a network? That doesn't seem right - I'm sure I've seen screenshots of the GUI showing a list of networks. Or is this a hardware issue? The wireless adaptor seems to be working fine, as I'm connected, and the terminal correctly displays wireless networks that are in range.

More info:

In the terminal, I can show that the computer detects a whole bunch of wireless networks that the GUI doesn't display. Here's the output of iwlist wlp5s0 s | grep SSID

                ESSID:"Libbetshouse"
                ESSID:""
                ESSID:""
                ESSID:"xfinitywifi"
                ESSID:"NETGEAR06_2GEXT"
                ESSID:""
                ESSID:""
                ESSID:"NETGEAR06"
                ESSID:"HOME-5F11-2.4"
                ESSID:"xfinitywifi"
                ESSID:"HOME-8402"
                ESSID:""
                ESSID:"xfinitywifi"
                ESSID:"Steadfast"

Here's the output of lshw -class network

Finally, here's a screenshot of the networking drop-down menu when I am connected to the wifi network I've been using (notice that no other networks are displayed):

This is a bug that has yet to be fixed: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1569959

In the meantime, restarting Network-Manager usually corrects it (until the next time you suspend or reboot):

sudo systemctl restart network-manager.service

  • That does work in the meantime!! Thank you so much for the work-around! – redoak Jul 9 '16 at 16:23
  • @redoak To make it a little less annoying, you might consider making an alias for that command, rather than having to enter the whole thing into the terminal each time. – Alcuin Arundel Jul 9 '16 at 16:29
