I'm new to Linux and Ubuntu and I have been using Windows for years, but viruses made me consider Linux. I first tried elementary OS because it is easy to use, I enjoyed it a lot but after surfing the web for quite some time my wifi disconnects and only reconnect when I reboot.

I've googled similar problems, but none of the solutions worked. After days of frustration I decided to Install Ubuntu 13.10 in hope the problem is limited to elementary OS, but Ubuntu 13.10 also has the same problem.

I am able to use Wifi for an hour or two but it would disconnect and would only reconnect if I reboot, the time before it disconnect is never consistent. sometimes it only last for 30 minutes, some times it last for 4 hours. most of the time it disconnect when there's no internet activity.

rfkill unblock all does not work and I have also reset my BIOS as suggested in the threads but none of it worked. I even replaced gnome-network-manager with wicd, but it still don't work.

In most thread I read the asker always put the result of lsmod and lspci with his/her question so i will put it as well, though I do not really know what they are for.

lsmod
