Ubuntu freezes when connecting to Wifi hotspot

Question

When ever I try to connect to WIFI hotspot, ubuntu freezes. By hotspot I mean wifi network where you first connect to the network without password then enter it in a dedicated page of a web browser. By freeze I mean that the only action I can do is alt+sys+REISUB

I can connect to my wifi at home without any issue, or to the wifi of my smartphone when sharing connection. For instance command iwconfig result in :

eth0      no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:"AndroidAP"
          Mode:Managed  Frequency:2.437 GHz  Access Point: 02:1A:11:F5:9B:A7
          Bit Rate=72.2 Mb/s   Tx-Power=20 dBm
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=70/70  Signal level=62 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:2  Invalid misc:72   Missed beacon:0

lo        no wireless extensions.

I have Ubuntu 14.04. Here is my network controller

~$ lspci | grep Network
03:00.0 Network controller: MEDIATEK Corp. MT7630e 802.11bgn Wireless Network Adapter

I installed Mediatek MT7630E Combo Linux Driver

I tried to connect via command line but ubuntu freezes after :

~$ iwconfig wlan0 essid NETWORK_ID

No specific logs.

I can give more information if needed as I have the results from this script.

I tried to google this but without much result.

Does someone knows where it comes from ? if you want me to retrieve some specific info on my system, explain me how to get it: I am new to Ubuntu.

@Pilot6 thanks for you comment. I have not the same issue : I have installed the proper driver, wlan0 appears in iwconfig, and I can connect to some wifi. Just in case I tried to install the drivers mentioned your link, the issue is still there. — Pierre, Oct 23 '15 at 08:16

I tried to install different drivers without success.

Moving from ubuntu 14.04 to 15.10 and installing latest drivers (from here) solved the issue.

FYI moving to 15.10 may trigger some issues (it was not the case for me)
