I have a problem with Airplane Mode (AM) in elementary OS Loki (latest release, updated as of today). I am not sure whether this is a Gnome issue (see for instance this thread), a Pantheon issue or something completely different.
Here is my problem: I cannot disable AM; if the radiobutton is flipped, AM remains in the same state. I can only choose from VPN and Proxy, but no network interfaces are present.
Invoking the following command
sudo rfkill list all
returns that no devices (
hci0: bluetooth and
phy0: Wireless LAN) are soft or hard blocked. I tried
sudo rfkill unblock 1
which correspondes to
phy0. Also tried blocking and unblocking it. There is a hardware switch on the laptop. I have tried to switch this back and forth, and it does indeed make
phy0 to appear as soft blocked. This does not yield a solution, though.
Let us look in the Network manager's internal state:
[main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=true
OK, so that is not it... Moreover,
ifconfig states that only the loopback interface is enabled. Running
ifconfig [dev] up
makes the device show up when running
ifconfig, but it still does not give me a network connection. Subsequently running
up does not remedy either.
I tried starting elementary OS in recovery mode. First, I enable network and then, resume the process arriving at the desktop. Now, the network works perfectly (however, the network settings still reports that Airplane Mode is ON), so it is clearly not a hardware issue.
Finally, I have also tried resetting to defaults (button in the About window). This had virtually no effect at all on the network manager. I really want to avoid reinstalling elementary OS for this reason.
