I recently installed Ubuntu 12.04 LTS. I'm facing the following 2 problems that I don't understand how to solve it:
Wireless connection was running normally when I installed the Ubuntu without the need of any additional driver, however on the next day it just stopped to detect any available wireless connection.
Due to 1st problem, I connected my PC to my Internet huddle with cable. It works pretty smoothly, but on the next day it stopped working working again (I did installed 2 new language package on that day - Korean and Chinese simplify). And what confused me even more is that suddenly my wireless connection started to work again.
It is like the OS alternatively disable & enable all my network adapter.
I'm new to Ubuntu or Linux in general, I don't know what configuration I have to do. What are the information I need to provide here in order to understand & solve my problem?
Wireless : D-Link Wireless N 150 USB adapter
huddle : Yes Huddle 4G mobile hotspot (from http://www.yes.my/v3/personal/devices/huddle.do)
Other details: sudo rfkill list
