Here is the information gathered about my wi-fi using the script provided by you guys here at AskUbuntu: http://paste.ubuntu.com/12733543/
I use a laptop dualboot Windows 7 and Ubuntu 14.04 LTS.
I just moved to a hostel and the wifi is provided by the hostel.
In the first few days, I had no problem using the wifi. However, I noticed wifi connection problem since yesterday and it is turning on and off. In other words, the connection would break at any time. I tried to use Windows 7 and there were no wi-fi problem. I could stream movies smoothly.
Could you please help me out? For now I use iphone hotspot shared via cable to go to internet.
