So, I have the following problem. I have bought a Lenovo T460p some eight months ago and it has the non-reproducible problem that the network manager, from time to time, refuses to show Wireless as an option as if WiFi just wasn't supported.Usually, the problem is gone after a restart. However, this time a restart didn't help. Hence, I am trying to figure out whether this is software or hardware related? From research I know that I am not the first one to encounter a network relates issue with Linux Mint. Anyhow, I am kind of worried that it might be a more serious problem nonetheless.Do you have any suggestions on how to debug this?Some information:Product name: Lenovo ThinkPad T460pOS: Linux Mint 18 Cinnamon 64-bitLinux Kernel: 4.4.0-78-genericOn running dpkg -l | grep network-manager to obtain the version of the network-manager in question, I get this output:ii  network-manager                               1.2.6-0ubuntu0.16.04.1                       amd64        network management framework (daemon and userspace tools)ii  network-manager-gnome                         1.2.6-0ubuntu0.16.04.3                       amd64        network management framework (GNOME frontend)ii  network-manager-openconnect                   1.2.0-0ubuntu0.16.04.1                       amd64        network management framework (OpenConnect plugin)ii  network-manager-openconnect-gnome             1.2.0-0ubuntu0.16.04.1                       amd64        network management framework (OpenConnect plugin GNOME GUI)ii  network-manager-openvpn                       1.1.93-1ubuntu1.1                            amd64        network management framework (OpenVPN plugin core)ii  network-manager-openvpn-gnome                 1.1.93-1ubuntu1.1                            amd64        network management framework (OpenVPN plugin GNOME GUI)ii  network-manager-pptp                          1.1.93-1ubuntu1                              amd64        network management framework (PPTP plugin core)ii  network-manager-pptp-gnome                    1.1.93-1ubuntu1                              amd64        network management framework (PPTP plugin GNOME GUI)
Issue with wireless connection. OS problem or hardware broken?
