I finally did install Ubuntu 14.04 on my Asus notebook. Now, my laptop is on dual-boot Windows7 and Ubuntu. All is working well, however, after getting the updates sudo apt-get update and setting up the wireless connection, I noticed something very strange and annoying: as my laptop is connected, if I try to move through the rooms I lose the Internet signal.
If I boot to Windows, at the same distance, I get the internet signal very well. In summary :
- From 2 m off the router : Ubuntu and W7 both receives well
- From 8 m or more off the router: W7 receives normally and Ubuntu receives nothing and gets disconnected.
