It seems to be an issue related to "nm_urfkill_get_wlan_state()" coming from an Ubuntu patch.

Some additional information:
- no similar issue on the same laptop with Ubuntu ***desktop*** 15.04/15.10
- same issue with Ubuntu ***server*** 15.04/15.10

I've modified the title to reflect these informations.

summary:

- [Ubuntu 15.10] Realtek RTL8723AE cannot connect to WPA2/AES
+ [Ubuntu Server 15.04/15.10] Realtek RTL8723AE cannot connect to WPA2/AES

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".
