I am running ubuntu 12.04 on my samsung laptop but the wifi connection keeps dropping every minute. I have another dell laptop which also has ubuntu 12.04 but wifi works fine on that. And if I use my samsung laptop at office as its my office laptop wifi works fine. So, I don't understand what the problem is. I have googled it and found solution like set ignoring IPv6 setting but that still does not make any difference. So I don't understand where the problem is if its with my network provider or its with my laptop. I can't blame my network provider as wifi works fine on my other devices including Ipad, mobiles and dell laptop. Even I can't say clearly that its problem with my laptop as wifi works fine in my office. Previously I had ubuntu 13.04 on my samsung laptop and I was having the same issue so I uninstall it and install 12.04 and issues is still the same.
