I've recently installed Ubuntu, but it was running too slow on my computer and I installed the lubuntu-core package through the Synaptic Manager. So now I'm using Lubuntu (sorry but I am a complete newbie and don't know how to check its version).
Anyway, my wifi connection speed is much slower now than it was on Windows.
I've been having some problems with the wi-fi connection on Ubuntu 14.04. I have a Toshiba Satelite with pre-installed Windows 8 which I uninstalled. The wi-fi connection on Windows was really good, but since I installed Ubuntu the connection is slow and unstable. I've been using some help from here that i thought it could help, but nothing.
