[Bug 1510648] Re: [Ubuntu Server 15.04/15.10] Realtek RTL8723AE cannot connect to WPA2/AES

  Thread Previous • Date Previous • • Thread Next 
I've made some progress: 
If I remove the following lines from /etc/network/interfaces:
iface wlan0 inet dhcp
iface wlan0 inet6 auto

NetworkManager errors "nm_urfkill_get_wlan_state: assertion 'self->wlan_proxy != NULL' failed" are gone:

However, it seems that the module rtl8723ae is not loaded:
lsmod | grep -i rtl8723ae

This is strange because I can see some WiFi networks in the top right hand side menu.
Furthermore, if I try to connect to a WiFi hotspot (Nexus 5 here), NetworkManager tries to connect to the Nexus 5 bluetooth interface (BC:F5:AC:4B:72:11):

Now, if I try to turn off bluetooth, Ubuntu goes into airplane mode
which disables WiFi as well - I'm unable to turn off bluetooth alone.

Connecting Ubuntu Server to Nexus 5 Bluetooth: OK

Reconnecting it to Nexus 5 Hotspot: KO

This seems to indicate that WiFi & bluetooth interfaces are considered as the same interface for this operation, which is very strange.
Ubuntu Server tries to connect to the bluetooth interface of the Nexus 5 hotspot, probably because the rtl8723ae module is not loaded.

If I try to manually load the rtl8723ae module in /etc/modules:
rtl8723ae

update-initramfs-u
shutdown -r now

It does not change anything.

I believe we should try to solve the errors shown in "modinfo
rtl8723ae".
